The figure, not drawn to scale, consists of 1 Square P and 1 Circle Q whose areas are in the ratio of 3 : 1. Given that
310 of Square P is shaded, what fraction of Circle Q is shaded?

Area of Square P is the repeated identity.
Shaded area of Square P is the same as the shaded area of Circle Q.
LCM of 3 and 10 = 30
Fraction of Circle Q that is shaded
