12 trophies cost 60 dollars
so 1 trophy cost 5 dollar.

By question 4(12+x) = 60
or, 48 + 4x =60
or, 4x = 12
or, x = 3

Similarly,
6(12-y) = 60
or, 12-y = 10
or, y = 2

x>y

IMO (D). The question didn't say or imply all the trophy has the same price.

unless nothing is mentioned all trophies have the same price that is the assumption.
