Puzzle 5
A very long time ago, at the beginning of the week, I was given some money for my birthday.
On Monday, I spent a quarter of the money on clothes.
On Tuesday, I spent one third of the remaining money on music.
On Wednesday, I spent half of the remaining money on games.
Finally, on Thursday, I spent the last £12.50 on a book.
On Wednesday, I had £12.50 x (1 ÷ one half) = £25.
On Tuesday, I had £25 x (1 ÷ two thirds) = £37.50.
On Monday, I had £37.50 x (1 ÷ three quarters) = £50.
