Question

I have some money, I spend half at the bookshop, a quarter at the supermarket and an eighth on sweets. I have £3.25 left.how much did I have to start with

Answer 1

So far you have spent
1/2 + 1/4 + 1/8 of your money or 7/8, leaving you with 1/8 of your money.
(1/8)x = 3.28
x = 8(3.25) = £ 26
