Ali, Benny and Charles had 255 stamps altogether. Ali gave 3/8 of his stamps to Benny and 1/5 of them to Charles. After that, all the three boys had the same number of stamps. How many more stamps did Charles have than Benny at first?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A + B + C = 255

 

Ali's stamps => x

 

x - (3x/8 + x/5) = 85

 

x = 200       (Ali's stamps at first)

 

3x/8 = 75     (Ali gave to Benny)

 

Benny had 10 stamps at first.

 

x/5 = 40       (Ali gave to Charles)

 

Charles had 45 stamps at first.

 

Charles had 35 more stamps than Benny!
