The figure, not drawn to scale, consists of 1 Square R and 1 Circle S whose areas are in the ratio of 4 : 1. Given that
15 of Square R is shaded, what fraction of Circle S is shaded?
Area of Square R |
Area of Circle S |
4x5 = 20 u |
1x5 = 5 u |

Area of Square R is the repeated identity.
Shaded area of Square R is the same as the shaded area of Circle S.
LCM of 4 and 5 = 20
