PEN - MEN = 87 can be rewritten as

(16x + 5x + 14x) - (13x + 5x + 14x) = 3x

This gives x = 29 (as 3x = 87)

Now,

BOY - CAN = 24x

Substituting x = 29, we get the answer as 24*29 = 696

PEN - MEN

(16^2+5^2+14^2) - (13^2+5^2+14^2) = 87

BOY - CAN

(2^2+15^2+25^2) - (3^2+1^2+14^2) = 648.

Is it correct?
