Find the missing number in the following (image )

Answer 1

Though this question isn't difficult at all, but it is a good test for your observational skill.
The outer circle numbers when multiplied in a certain manner give the inner numbers,
8 x 7 = 56 7 x 4 = 28 4 x 15 = 60
So the answer is 15 x 8 = 120.
