Answer 1

Answer:

here your answer

If the ratio of money in Obi's wallet to Rudy's wallet5:2

then Obi had 5x and Rudy has 2x in their wallets.

Obi spent £20 and 5x-20 left. Obi now had £8 less than Rudy

thus,

2x-(5x-20) =8

2x-5x+20=8

-3x=-12

x=4

obi 5x=5*4=20

rudy 2x=2*4=8

This means that initially Obi had £20 and Rudy had £8
