The ratio of Aziz's money to Osman's was 2:1 at first. After Aziz spent $10, the ratio became 4:3. How much money did each boy have at first.

 

Aziz started with $30 and Osman with $15, which is a ratio of 2:1

$30 - $10 =$20 Aziz was left with, or $20:$15 which is a ratio of 4:3

Or If Aziz started with x dollars, Osman had 1/2x

So, (x - 10) / 1/2x =4/3, solve for x

x=$30 Aziz orinal amount.
