If a blouse costs £17.68, how much change will you get from a £20 note?

• £2.32

• £2.30

• £2.02

• £2.23

Answer explanation

£20 - £17.68 = £2.32. If you can do this in your head, that's fine; otherwise, use the tip. TIP: (1) Increase the number of pounds that are to be subtracted by £1 and do the subtraction: £20 - £18 = £2. (2) Subtract the pence from 100: 100 - 68 = 32. (3) Add the pounds and the pence together to get the final answer: £2.32

Jack bought a pair of trainers (£75.99), a track suit (£60.99), and a running vest (£14.99). How much did he spend in total?

• £151.79

• £151.97

• £15.19

• £152

Answer explanation

The correct answer is £151.97

£75.99 + £60.99 + £14.99 = £151.97. This addition can be done as follows: £76 + £61 + £15 = £152 - £0.03 = £151.97. The 3 p comes from rounding each of the three prices up by 1 p. Get used to this annoying practice of seeing prices ending in 99 p: it's a real pain in the neck!

• £0.38

Answer explanation

The correct answer is £38.44

£175.98 - £137.54 = £38.44. Subtract the pounds and the pence separately, then add them together: £175 - £137 = £38 and 98 - 54 = 44 p ∴ £38 + £0.44 = £38.44
