Question

Harry and his sister Jess have some money in the ratio Harry : Jess = 1:4

Harry has £7.35
They pay £16.99 for a present for a friend.
Harry uses
3/4 of his money.
Jess pays the rest.
How much money does Jess have left?

Answer 1

£17.92

Explanation:

Harry : Jess

1 : 4

£7.35 : £29.40

(for every 1 Harry has, Jess has 4, so Jess = 4 x 7.35 = 29.40)

PRESENT:

Harry uses 3/4 of his money = 0.75 x 7.35 = £5.51

So Jess pays: 16.99 - 5.51 = £11.48

Jess has left: 29.40 - 11.48 = £17.92
