The drawing shows a sculpture as seen from above.

8. Which of these could not be a view from one of the sides?
1
0

## Explanation

As in the bird’s eye view diagram the border around the smaller central square is continuous around the entire of the small square, it must be that each side of the sculpture is level when viewed on from any of the sides. Hence, A could not be a view from the side because a sqaure chunk has been removed. The remaining options are all possible.

The design of a tile for a bathroom wall is shown below:

26. Which of the following patterns may NOT be made using only a number of identical tiles as shown?
0
0

## Explanation

Pattern B can not be made using only the tile shown. This can be seen by looking at the leftmost tile in the 2nd row of pattern B (for example), which shows two curved black lines arching over opposite corners, whilst the tile shown in the question has a curved black line in only one of the corners and a more square black line in the opposite corner (rather than another curved black line). Therefore, B uses a tile other than the one given in the question. All the other patterns use only the tile given in the question.

Vinod and Sarah are about to move some cube-shaped boxes that have been left in the middle of a store room. The appearance of the boxes from above and the positions of Vinod and Sarah are shown below.

Vinod sees this:

50. Which of the following cannot be the view that Sarah sees?
0
1

## Explanation

Vinod can see a stack of 3 boxes in the leftmost column that he can see. The bird’s eye view from above shows that this leftmost column from Vinod’s view consists of a single stack of boxes. This means that that stack is exactly three boxes tall and therefore any of the answer options in which the middle column from Sarah’s view is less than 3 boxes tall cannot be possible. This means that answer option D is not possible and therefore that is the answer.

The diagram below shows a rather unusual conference table which may take up a range of configurations. The three pieces are hinged together at the points shown by the circles:

8. Which of the following shapes could NOT be made from this table?
0
0

## Explanation

A can easily be made by moving the inferior points of the two side tables towards the centre until they touch. B can be made by rotating the left side table so that its largest side is against the largest side of the table in the middle and rotating the table on the right side so that its most superior (diagonal) side is against the right side of the middle table. C can be made by rotating the table on the left side 180 degrees clockwise and rotating the table on the right side 180 degrees anticlockwise. E can be made by rotating the table on the right side so that its largest side is against the largest side of the middle table and rotating the left table 45 degrees anticlockwise. Therefore the only shape that cannot be made must be D.

This is a map of the island of Metallica showing the eight main towns (labelled P – W) and the roads that connect them, together with a chart giving the shortest distance (in km) by road between each pair of towns:

26. Which of the towns on the map is Nickel?
1
5

## Explanation

Nickel is 28km from Gold, so Nickel must be at a dot which has a line representing 28km attached to it. This could be P, Q, W, V, S or T, but since P and V are not given as answer options these can be eliminated, so Nickel could be Q, W, S or T. The next closest town to Nickel is lead, and since there are no lines representing 40km, this must be made up of 2 or more lines. We need to find which of Q, W, S and T are joined to 2 or more lines which add up to 40km. Q is not, W is (W to S=28+12=40), S is (S to W=12+28=40), T is (T to V=28+12=40), so eliminate Q. The next closest town to Nickel is Tin 63km away, using a similar method as we did for 40km: W is not joined to any number of lines equating to 63km, nor is S, but T is (S to T to V to U =28+12+23=63). Therefore Nickel must be T

Boland City has just installed a new tram system. Several artists have been asked to come up with a map of the system which, whilst it may not show the exact relative positions of the stations, shows the connections between them correctly.

The five maps are shown below (the names of the stations are not marked).

32. Four of the artists drew possible maps, but the fifth got the connections wrong. Which map below is based on incorrect connections?
0
1

## Explanation

Each diagram has 4 dots connected to 3 other dots and has 2 dots connected to 2 other dots, except C, which has 5 dots connected to 3 other dots and only 1 dot connected to 2 other dots. Therefore the connections on C are different to on all the other diagrams, so C is the answer.

The pattern below shows part of the tiling of a large floor in a community It is made up of two types of tile: a hexagon and a triangle.

44. For a sufficiently large expanse of flooring, approximately what proportion of the two types of tile will be required?
0
1

## Explanation

We need to find the repeating unit that would make up this pattern with no overlap of tiles. Such repeating unit can be demarcated by counting 6 triangles down from the top left corner, 6 triangles along the top (diagonal) row, then the triangles on the left of the vertical line level with the right edge of the upper left hexagon above the northeast edge of the hexagon, then the remaining triangle above the line level with the northeast edge of the hexagon (against the hexagon’s northwest edge). This would give a total of 12 triangles for 1 hexagon.

There are seven books on my shelf, which are of various sizes. When I look at them straight on I see the following picture:

I now look at them from the left-hand end (in the direction of the arrow).

14. Which one of the following diagrams is not a possible view when seen from the left-hand end?
0
0

## Explanation

From the view when looking that the books in the book shelf straight on, we can only determine the relative heights of the books, but not their widths. Hence when we look at them from the left, we can determine which of the views are possible on the basis of the different heights, but not the widths. From the view straight on, we can see that we should be able to see the top edges of at least 4 books, (highlighted in blue) simply because each one is taller than the previous ones. Therefore, any answer options where we can see these 4 books of different heights on the leftmost edge of the view is possible, as shown for options A and B. However, in answer option C, we only see 3 books on the leftmost edge, and therefore this is not a possible view.

Various shapes may be made by overlapping two transparent squares, for example the dark shaded hexagon shown below:

25. Which one of the following shapes cannot be made as the overlap of two transparent squares?
0
0

## Explanation

This questions requires that you visualise the two squares in different arrangements that produce the overlaps shown in the answer options. It is useful to look out for parallel sides and 90-degree angles in the overlapping shape as those can help indicate the placement of the two transparent squares. As shown, answer options A, C, D and E are all possible, and therefore the correct answer is option B.

A is possible as the rectangular face shown in A is the rectangle at the top of the card in the diagram given in the question and is adjacent to the triangle on the right hand side of the diagram. B similarly shows the rectangular face at the bottom of the diagram. C shows the middle rectangular face, and the triangular face on the right hand side of the diagram in the question. D is like A but includes the triangular face on the left of the diagram (rather than the one on the right shown in A). Therefore E must not be possible.

The diagram below shows Morden Hall and the network of paths within the grounds.

When the owner takes his dog for a walk he always starts and finishes at the intersection outside the front door and (keeping to the paths) walks one complete triangular route.

44. How many different routes does he have to choose from? (Clockwise and anticlockwise around the same triangle counts as one route only.)
0
0

## Explanation

If we give each triangle a name: The top triangle is triangle 1, the two triangles below are L and R triangle 2 and the two triangles at the bottom are L and R triangle 3. There are 5 separate triangles in total, each of which touch the intersection, therefore each is a different possible path that could be taken, giving 5 possible paths so far. Now we need to find triangular paths that can be made by joining two or more triangles together. The following combinations of triangles are possible: 1+L2, 1+R2, L2+L3, R2+R3, L2+L3+R3, R2+R3+L3, giving us 6 more possible paths. So the total number of possible paths are: 5+6=11.

This diagram shows the positions of three ornithologists on a The squares on the map are 1000m along each side.

The ornithologists are trying to find an injured falcon which is carrying a radio transmitter. Each ornithologist has a radio tracking device. The direction-finding part of the trackers is not working but the signal strength gives an indication of the distance to the bird.

The ornithologists have the following information about the distance from themselves to the bird.

Gordon is at position 22,06; signal strength indicates more than 500m and less than 2000m.

Helen is at position 23,06; signal strength indicates more than 100m and less than 2000m.

Ingrid is at position 23,08; signal strength indicates more than 1100m and less than 1800m.

18. At which one of the following grid points could the bird be located?
0
0

## Explanation

The quickest approach to answering this question is to simply run through the different answer options and see if they meet the requirements. As we start off with A we can see that it meets the distance limits of both Gordon and Helen. However, it is not instantly clear at first glance whether or not this lies within the distance range indicated from Ingrid’s location. As 22,07 is the point diagonally across from Ingrid it will be more than 1000m away from Ingrid but it is less clear whether it is further than 1100m away. Hence, we can go through the remaining options to check whether all the rest can be excluded. B and C can be excluded as they are clearly more than 1800m away from Ingrid. D is further than 2000m away from Gordon, while E lies 1000m away from Ingrid even through the signal strength suggests that the falcon is at least more than 1100m away. So, A must be correct. An alternative approach may be to annotate the image with circles indicating the different signal ranges provided but this will only take you longer to answer the question.

The trapezium below may be cut into four identical pieces.

32. Which of the following pieces can be used four times (flips and rotations are allowed) to make up the trapezium?
0
0

## Explanation

The shape given in A can fit into the leftmost part of the trapezium, keeping A in the same orientation in which it is shown. If we then rotate shape A 180 degrees, it can fit against the vertical side of the first of shape A that we fitted into the trapezium. Keeping shape A in the orientation in which it is given, we could then fit it so its longest (diagonal) side fits against the longest side of the second shape A we used. Finally, flipping a fourth of shape A in the vertical plane would allow it to fit into the rightmost part of the trapezium.

Five pictures of solids made by sticking cubes together are shown below.

44. Which one of the following (A-E) is a different shape from all the others?
0
0

## Explanation

All the shapes have the same L shaped ‘backbone’ and it is therefore easier to compare similarities and differences by focusing upon the 2 cube protrusions from this ‘backbone’. In doing so we can see that shapes B and E are the same and the protrusions here extend out in opposite directions while A and D are also the same. The only shape that is different to all the others is therefore C. It can be tempting to interpret the question to mean that 4 of the shapes are the exact same with one odd one out, which can become confusing when trying to answer the question. Since the question is only asking for one shape that is ‘different from all the others’, this doesn’t necessarily mean that the other four shapes are identical – just that there is at least one other shape that is identical to it.

In the committee room of my cricket club there are four tables, all identical to the one shown below.

50. Which of the following arrangements is it not possible to make by putting four of these tables together?
0
0

## Explanation

We need to see which of these shapes can be made by visually attempting to fit 4 tables into it, or by drawing lines on the shapes to show separation of the tables. For shape A, the 1st table in the orientation shown in the diagram can fit into the top left corner of the shape, and rotating the 2nd table by 90 degrees clockwise, would allow it to fit on the bottom left corner; the same can be achieved with two consecutive rotates of 90 which would allow the table to fit into the bottom right and then the top right corner. Shape B can be made by fitting one table into each of the top corners, and then making the remaining rectangles by taking the table in the orientation given, rotating another table by 180 degrees and fitting these together.

44. Which one of the following gives a possible view of the church?
0
0

## Explanation

A and B are not correct because they contradict the description that only doors are on the westernmost end of the church. C is incorrect because the description states that there are 3 south-facing windows, whereas in the picture there are only 2. D is incorrect because when viewing from the South the longer horizontal part of the church would be on the left, like in diagram C. Therefore E is the correct answer.

Whenever my friend Alistair writes to me he does so entirely in code. He always uses symbols for letters but changes the code each time, so any particular symbol does not necessarily stand for the same letter of the alphabet every time.

## Explanation

The 4th and 8th symbols are the same, suggesting that the 4th and 8th letters of the word must be the same. The only word given that has this is ‘sometime’, therefore E is the correct answer. You may have incorrectly thought that the answer was ‘saturday’ because the downward pointing arrow represents letter ‘A’ in the example given when Alistar’s name is written, however the text states that any particular symbol does not necessarily stand for the same letter of the alphabet each time, and the 4th and 8th letters are not the same in ‘saturday’.

Four trees stand at the corners of square field X. They are photographed from field Y, from every possible direction, close up and from a distance, but never so that one tree stands in front of another.

50. In how many different orders, left to right, can the trees appear in the photographs?
1
0

## Explanation

If we imagine that we are taking the pictures as we move from right to left in field Y, we can see that in the initial pictures the order will be 1-2-4-3, followed by 1-4-2-3. Right in the middle of field Y, if pictures are taken from close up then the order will appear to be 1-4-3-2. As we continue onto the left side of the field the order will initially appear to be 4-1-3-2 and then 4-3-1-2. This means that 5 different orders are possible and the correct answer is therefore E.

## Explanation

For diagram A, height would initially increase with time at a constant rate, then at a faster rate when it gets to the open trapezium-like shape, from when the rate of height increase with time will decrease, ending at the original rate, which is shown by the second graph. For diagram B, the rate of increase in height would initially decrease at it gets to the centre of the circle, then the rate would increase until it gets to the two vertical lines, when it’s rate of increase in height with time would be at it’s highest and would remain constant, which is shown by the fourth graph. For C, the rate of increase in height would remain constant throughout, which is shown by the first graph. For E, the rate would initially be constant, before instantaneously switching to a higher rate, shown by the third graph. For D, the rate would for the most part be constant, then increase, before again remaining constant but at a higher rate, which is not shown by any of the graphs.

I have a square field which is exactly one hectare (100 m × 100 m). On Monday I was surprised to find 4 mushrooms growing in a 1m square formation, in the centre of my field. On Tuesday the group of mushrooms had expanded to 16, which were all 1 m apart.

When I looked at the group of mushrooms today (Wednesday), it had expanded to 36.

37. If the area covered by mushrooms continues to expand at this rate, how many days (including today) will it be until my field is covered in mushrooms?
0
0

## Explanation

Adding another square border of dots around the 36 mushrooms adds 2 mushrooms to each row, making the total square 8x8m (64 mushrooms). So the number of mushrooms ascends every other square number (2×2=4, 4×4=16, 6×6=36, 8×8=64, etc.). Because the field is 100x100m, and the number of mushrooms in each row increases by 2 each day, to find the answer: 100/2=50 days to fill the whole field from the very start. Because the mushrooms started to grow 2 days ago, subtract 2: 50-2= 48 days.

A tiler has encountered a problem when tiling a kitchen floor. He is one tile short of completing the job. This is indicated by the greyed-out area in the diagram below which shows part of the kitchen floor:

There are some odd pieces of tile left over that could be used to complete the job. Three of these, if combined, would fit the area exactly.

14. Which three pieces of tile could be pieced together to fit into the remaining corner area? (The tiles are shown face up and cannot be laid face down.)
0
0

## Explanation

Remember to take note of the fact that the tiles are shown face up and cannot be laid face down – so although you can rotate the shapes you cannot turn them over. Just a quick scan of the shapes shows us that shapes 1 and 2 pair well with each other but not with the other shapes as 2 has a protrusion in the centre, which tile 1 can accommodate unlike the other shapes. Therefore, any combinations with just 1 or just 2 are less likely to work. This alone allows us to rule out options B-E. However, it is important to still confirm this by attempting to visualise whether tiles 1,2 and 5 fit together to form the L shaped area and we can see that they do, leaving us with A as the correct answer.

Instructions were given to shade 5 particular squares on a grid of 16 squares. One student shaded in the squares as instructed, but the other four got exactly 1 square wrong.

32. Which one of the five grids below shows the correct shading?
0
1

## Explanation

To answer this question we need to compare two grids at a time. If the grids differ by 1 square only, then it is possible that one of them is correct and if they differ by more than one square, then neither are correct. The correct grid will differ from each of the other grids by only one square. Hence if we compare A with C we can see that they differ by 2 squares – so neither can be correct. Same is true for when we compare B and C as well as D and C. so we can rule out options A, B, C and D, giving us the right answer of E. Just to confirm, we can check and see that E only differs by 1 square when compared to each of the others, hence it’s the correct grid

## Explanation

Net A cannot form the L-shaped box because if you, for example, fold along the left and right vertical dotted lines so the two L-shaped faces are parallel to each other, the upper left square on the diagram of the net would overlap with the lower part of the L-shaped face on the right in the net diagram. This would leave a gap in the position of the lower square face (the rightmost square face in the diagram of the box given in the question). All the other nets will from the box when folded.

Amy’s view of the pile is:

26. Which one of the following could not be Ben’s view of the pile?
0
0

## Explanation

The answer is E , as from Amy’s view, you can see that the second pile from the right appears 7 boxes tall. This means that at least one of the piles coloured in green must be 7 boxes tall and as a result, at least one of the two rightmost piles must be 7 boxes tall in Ben’s view. This is true in all answer options except for E, so that is the correct answer. Top Tip: For these kinds of questions, as you usually only have to figure out which of the views is not possible, make sure to start off with the piles that are easiest to work out, such as the leftmost pile from Amy’s view, as from the bird’s eye view we can tell that it’s only one pile and therefore it must be 5 boxes tall – and therefore the second pile from the left in Ben’s view must be atleast 5 boxes tall.

Connem Ltd. has recently adopted a new company logo.

A large plastic version of the logo has just been delivered to the office, to be attached to the outside of the building. Unfortunately, in transit, the plastic has broken into two pieces, as shown below:

32. Which one of the following could not be Connem’s new logo?
1
0

## Explanation

This question requires you to visualise the shapes provided and see which of the answer options could not be made from the two pieces. Make sure to draw on the shapes to figure out whether or not the combination is possible. From this we can see that answer options A-D are all possible and the correct answer is E.

The diagram below shows part of a map of Ruralia.

A group of students are on an expedition and must meet their teacher at Longwood, grid reference 787634. Unfortunately, they have been given a version of the map with the numbers missing from the gridlines, and the place names have been omitted too. They have a list of grid references for some places on the map, and are trying to work out which point to head for in order to be sure of meeting their teacher.

They have a set of instructions showing how the grid references work:

The grid reference of point P is 172427. Go to vertical line to the west of the point, read the number 17. Estimate how many tenths across the square the point appears at, hence 172. Go to horizontal line to the south of point P, read the number 42, estimate how many tenths up the square the point is, hence 427. This gives 172427 as the complete grid reference number.

Here is the list of the grid references / place names the students have been given.

38. Using this information to help you, which of the places marked on the map is Longwood?
0
0

## Explanation

Although this question can look quite difficult at first due to the amount of information provided, it is pretty straightforward once you understand how the grid references work. We can see some points are present at either extremes within the grid (both along the vertical and horizontal axis). Use these to label your axis. Along the horizontal axis, we can see a point at the left most extreme and scanning the grid references shows that the place with the highest number for the horizontal aspect is Lower Green, with 837654. If we label our horizontal axis accordingly, and note the fact that the grid reference for Long wood is 787634, we can see that the two points within the 78-79 square (horizontally) are W and Y. Between these, we can see that W is the correct answer as its most likely to be 787… whereas Y likely has a grid reference of 781… (which is Riverside).

Keith likes to draw ‘bump charts’ to look at relationships. For instance, if 6 individuals were ordered by height, and it happened that the order was the same by weight, the bump chart would look like this:

Or if height was maintained for order on the left hand but lightness rather than heaviness on the right hand, the bump chart would be this:

50. If one axis is reversed in order (as in heaviness goes to lightness), which one of the following bump charts would not be symmetrical about a vertical line midway between the axes?
0
5

## Explanation

All options aside from C are anti symmetric, where the right side is the opposite of the left side. Therefore, they become symmetric about a vertical axis when one side is reversed.

Option C is already symmetric, meaning that it will become anti symmetric when one side is reversed.

Would this not also apply to d?

The see-through glass block below can be viewed from six sides, including from above and below.

20. Which one of the following is not a possible view?
0
0

## Explanation

We are looking for the impossible view; E is not possible because the indent in the rectangle is not closed at all in the 3D shape, so there would not be a line across the rectangle as is shown in E (birds eye view from above)

A digital display consists of seven segments which light up in different combinations to produce digits. For example, to display the digit ‘1’ the two right-hand segments light up as shown:

The display is used to show, in sequence, each of the digits 1 to 9.

24. What is the maximum and minimum number of times that any one segment lights up during this sequence?
0
0

## Explanation

This is a little time-consuming. I would recommend sketching out the digital display. Then above/next/beside each line segment, write which numbers between 1 and 9 would light up that segment. Each, the number 8 would light all of them, or the uppermost bar would be let by 2,3,5,6,7,8,9. The lower right hand bar is let by the numbers 1,3,4,5,6,7,8,9 which is eight, the maximum. The minimum is the lower left bar, which is only lit by the numbers 2,6,8, so three is the minimum, and the answer is C.

Consider the following net, which forms a hexagonal prism:

44. Which one of the following nets will form an identical prism?
1
0

## Explanation

For these kinds of net questions, try to find an easy pattern than you can look for within each net to rule out the incorrect ones. For example, here, we can observe where the top of the letter T on the hexagonal face lies. We can see that it faces a corner, so we can instantly rule out answer option B as the top of the letter T lines up with a side in option B. We can also see that the top of the letter T lies near the corner with the numbers 2 and 3 making up the sides of the prism. Scanning through the remaining nets allows us to rule out A and E, as the top of the letter T lies near the corner with the numbers 1 and 2 making up the sides instead. For D its 3 and 4 so it can also be ruled out. This gives us the correct answer option of C. If visualising this proves to be hard, it is also worth looking at the order of the numbers on the sides of the prism – this allows us to rule out D for instance, while we can rule out A and E because all the numbers are oriented sideways – so the wrong way round.
