Puzzle Details

Last weekend I was given my pocket money, which is meant to last me all week.

On Monday, I spent a quarter of my money on clothes.

On Tuesday, I spent one third of my remaining money on a CD.

On Wednesday I spent half of my remaining money on sweets.

Finally on Thursday I spent my last £1.25 on a comic.

How much pocket money did I receive?

Answer: £5.00.

Working backwards:

On Thursday I had £1.25.

On Wednesday I had £1.25 x (1 ÷ one half) = £2.50.

On Tuesday I had £2.50 x (1 ÷ two thirds) = £3.75.

On Monday I had £3.75 x (1 ÷ three quarters) = £5.00.
