Ahmad, Tim and Craig had 660 marbles altogether. Ahmad gave 1/3 of his marbles to Tim and 1/4 of his marbles to Craig. After that, the three boys had the same number of marbles. How many marbles did Craig have at first?

1/3A + T ==220 - what Tim received

 

1/4A  +  C ==220 - what Craig received

 

 A + C + T==660,solve for A, C, T

 

A==528 - what Ahmad had at first

 

C==88 - what Craig had at first

 

T == 44 - what Tim had at first
