The ratio of apples Andrew, Ben, and Declan had was 3 : 8 : 4. When Ben gave 21 apples to Andrew and Declan, all of them have the same number of apples in the end. How many apples did Ben have at first?

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

A : B : D = 3 : 8 : 4

 

3x + 4x +21 = 2(8x - 21)

 

x = 7

 

8x = 56

 

Ben had 56 apples  laugh
