The figure, not drawn to scale, consists of 1 Square A and 1 Circle B whose areas are in the ratio of 4 : 1. Given that
215 of Square A is shaded, what fraction of Circle B is shaded?

Area of Square A is the repeated identity.
Shaded area of Square A is the same as the shaded area of Circle B.
LCM of 4 and 15 = 60
