Picking up 8 is a good move as it means he can win on the next hand with different numbers rather than just relying on one number
Robin will win the game because on the next move. This is because he can win with more permutations of the remaining cards than Susan. Eg Robin could pick up a 1 or 3 and win the game as an example. Susans options are limited

13/40
 You have 1/4 shaded of the first square. 2/5ths shaded of the second square
 This is a question of being able to convert both fractions to the same denominator
 So this would be 20. 1/4 becomes 5/20 and 2/5ths is 8/20
 Then add both these together to get 13/40. Note its not 13/20 as you have to add the squares together which is unlike a normal fraction addition

c) 16mins
80/5
d) 1km
Peter took 15mins. If its 4km/h he walks, then after 15mins, he walks 1km
a) £102
10metres would be £10.20 * 10 = £102
b) 2.5metres
£10.20 * 2 = £20.40. This leaves £5.10 (£25.50 – £20.40)
£5.10 is exactly half of £10.20. So therefore total is 2.5 metres
a) 8.52am
8.15am + 37mins = 8.52am
b) 5.46pm
6.23pm – 37mins.
Slightly harder to calculate so take off 23mins first to get to 6pm. This leaves 14mins (3723). So then take 14mins off 6pm
So 5.46pm
a) 1/15
 Convert to the same denominator
 So this would mean Tom 3/5 = 9/15 and Jerry 1/3 = 5/15
 In total, 14/15ths has been eaten leaving 1/15
b) 250g
 If Tom had 3/5 = 150g, then 1/5 = 50g
 Therefore 5/5 = 250g
a) 83
(14*2)+55 = 28+55 = 83
b) 13
(9*2) = 18
3118 = 13
c) 22
d) 0
So for d), try c = 4 and 4 = 4. This will mean that 4*2 + 4 = 12 and this is equal to 4*2 + 4 as c & d are the same. So cd or dc = 0
462cm
Large Triangle = 16cm * 3 (all sides same as its equilateral). So 48cm
Middle Triangle = 7cm * 3 triangles * 3 sides (7 small triangles of 1cm each on the horizontal base tells us its a 7x7x7 triangle). So 63cm
Next size Triangle of which there are 3 = 3cm * 3 triangles * 3 sides = 27cm. There are 3 of them so 27cm
Smallest triangle = 36 small triangles all of 1cm per side. So 3cm *36 triangles * 3 sides = 324cm
Total of all of these is 48 + 63 + 27 + 324
16
5 numbers with mean 28 = 140 in total (5 * 28)
12 numbers with mean of 11 = 132 in total (12 * 11)
Total = 272
Mean = 272/17
64cm
Perimeter = 14+3+4+6+7+2+17+11
11/35
 Convert to the lowest common denominator which is 35
 So 2/5s becomes 14/35 and 2/7s becomes 10/35
 Add together so 24/35
 This leaves 11/35
a) See below. 1.52
Convert to the same metric. So in this case, its better to convert to decimals
b) 0.3
For this, you should use reverse bus stop. So 70 goes outside the bus stop with 21 inside.
Then add zeros on so that you can work out the answer to 2 decimal places
Then change the answer by the number of decimal places you added. So if you added 2 zeros, then your answer of eg. 70 would become 0.7
120
 Use BIDMAS
 20 + (1 x 7) = 27
 (20 + 1) x 7 = 147
 14727

b) 16
Use the approach below which is “reverse bus stop”
74
 (4+2) x 13 = 104
 4 + (2×13) = 30
 Difference = 104 – 30
1267
a) 0.24
6/25 = 24/100 = 0.24
b) 1.20
Convert all to decimals
So 0.35 + 0.6 + 0.25
70
 Use BIDMAS. (7+3) x 11 = 10 x 11 = 110
 7+ (3×11) = 40
 11040 = 70
1019
a) 8 minutes
Mode is most common number.
b) 6 minutes
Range is highest less lowest. 10 – 4
c) 7 minutes
Mean is Average. So add up all the times and divide by number of times
35/5 = 7 minutes
d) 1 minute
If mean is 6 and there are 6 days on record, then the total number of minutes late is 6 * 6. Remember , mean= total/number of instances. So 6=total/number of instances
So 36 – 35 = 1 minute
e) Bus was not late on the other days as the mean is 4 and number of days is 9. So 36 minutes late in total which is the same as the end of day 6
a) 7 hours 45 minutes
 With time questions, always work on going to the next key mark. So see below for the illustration:
 22:45 – 23:00 = 15minutes
 23:00 – 06:00 = 7 hours
 06:00 – 06:30 = 30 minutes
 Then add together = 7 hours 45 minutes
b) 17:20
 London to Hong Kong = 22:45 + 11 hours 35 mins
 Time would be 10:20
 But Hong Kong is 7 hours ahead. So time would be 17:20
1002
10:40
 Difference between 9am and 11am is 2 hours.
 Your dealing with ratios here 5:1. So 6 parts
 If you have 2 hours this is 120 minutes and each part is 20 minutes
 So 5 of these are 100 minutes. 1 part is 20 minutes
 So 100 minutes has passed which would mean 9am + 100mins = 10:40am
a) 7
Mode is the most common number. This is 7
b) 8
8+7+11+6+9+7 = 48
48/6
c) 5
Range is highest minus lowest
267,120
742
53424
26748
 Add a zero on. So 267,120
 Its rearranging the formula so it becomes 742 = 26712/36
 Double the base answer of 26712 so it becomes 53424
 Add on 36 to the original answer. So its 26712 + 36 = 26748. (ie an extra 1 x 36 since number changes from 742 to 743)

 24 people. 4 got off so this left 20. X people got on
 Assume zero got on for now at the last stop
 Second stop . 20 with 3 people getting on leaving 23
 If there were then 34 people, it means 11 people got on at the first stop
2 cucumbers
 5 tomatoes = 2 pounds weight = £3.00 cost
 So green peppers they bought 3 = 40p x 3 = £1.20 cost
 If they got 20p change and spent £4.20, then 60p was spent on cucumbers
 60p/ 30p = 2 cucumbers

750g of flour. £1.12 per kg. Therefore 750/1000 * 112/1. Think of HCF though. The HCF of 750 *& 1000 is 250. Therefore, given you know what 1000g (1kg) costs, you can work out 250g.
This would be £1.12/4 = 28p per 250g
So 750g of flour = 28p * 3 = 84p

Work backwards and reverse the signage to get to the starting point
5745 +67 – 237
£18
50 calls @ 17p per call = £8.50. Plus £9.50 for the fixed charge
11, 12.5
With sequences, its vital to look at the change number on number. So 5 up to 6.5 is +1.5. Then 6.5 to 8 is +1.5 etc
The pattern becomes clear. So 9.5 +1.5 = 11. 11+1.5 = 12.5
20
Calculate the Right hand side first which gives 12. Then re arrange. Take “8” over to the right hand side from left so it becomes a positive. So 12 + 8 = 20.

10,034 + 3,968. Write in Column format to ensure you align digits correctly
a) 555
Given 6*37 answer and 9*37, 15 * 37 will be these 2 answers added together
b) 888
(9*37 + 3*37) * 2
c) 499.5
(9*37)*3 = 999.
999/2
d) 962
(6*37) * 4 = 888. So this is 24 lots of 37. To get another 2 lots of 37, you take 1/3 of the answer for 6 * 37.
So 222/3 = 74. Then 888 + 74
a) 20
W 10 – 5 =X + 5 = Y * 2= 10 + 10 = Zoe
b) 2
Work backwards: Zoe calls out 4. Take away 10 as she added 10 to the number. This gives minus 6. Therefore, Yana must have had minus 3. Xanthe must have had 2.
c) 6.5
If Yana whispers 3, she was originally given 1.5. Xanthe must have had 6.5 from Wendy
d) 0
e) 9
f) 16
For these styles of questions, its vital to SENSE CHECK your answer. Its relatively easy to go back to your workings and ensure what you have done is correct
a) 20 minutes 20 seconds
In total its 19 minutes and 80 seconds = 20 minutes 20 seconds
b) 5 minutes 5 seconds
(20 minutes 20 seconds)/ 4 . If not sure, do the minutes first which is 5 minutes average. Then do the seconds which is 5 seconds average
c) 6 minutes 14 seconds
Range is the difference between the highest and lowest times. (8 minutes 17 seconds) less (2 minutes 3 seconds) = 6 minutes 14 seconds
36 & 64
Think of all the square numbers over 64….
81,100,121,144,169
36 + 64 = 100
a)0.569
Move decimal 2 places to the left when going smaller.
b) 2.007

Simple addition question
850g
Total Mass = 2.5kg.
Try and convert to the same metric to work through the calculation. So 2,500g
2 Bags of Carrots = 250g x 2
1 Cabbage = 750g
Total of Carrots + Cabbage = 1,250g . Plus 4oog for shopping bag = 1,650g in total
Therefore, Potatoes = 2,500g – 1,650g = 850g
a) 56
Work backwards. 20 MINUS 6 = 14 MULTIPLY BY 4 = 56
Sense check and work through from 56. 56/4 + 6 = 20
b) 7.5
6/4 = 1.5 + 6
c) even and multiples of 4
d) 48
18 minus 6 = 12. Multiply by 4 = 48
e) 216
Work backwads twice. 9 MINUS 6 = 15 X 4 = 60. Then again. 60 minus 6 = 54 x 4 = 216
a) 11
Work out RHS first = 26. Then rearrange formula if needed. ? = 26 – 15. Therefore ? =11
b) 5
2+20 = 27 – ?
BIDMAS
c) 0.5
18/3 = 6. ? x 12 = 6. This would bee 0.5
0.5
Put them in a Column Format. So….
Add zeros where necessary to ensure all numbers have same number of digits which makes the calculation easier

Simple addition question
3.6kg
Try doing the question in the same metric. So in this case, probably grams is easier to work with
Basket = 500g
Kitten = (600*4) = 2400g
Cat therefore = 6,500g (6.5kg) – 2400 – 500
Total = 3,600g.
Then convert back to KG
