Hi, can any one explain the answer for the following DS question
If P and Q are each circular regions, what is the radius of the larger of these regions?
(1) The area of P plus the area of Q is equal to 90Ï€
(2) The larger circular region has a radius that is 3 times 3 Times the radius of the smaller circular region.
OA is C
I think the answer should be A
Here's why
1. Let the radius of smaller region be 'r' and larger region be "R"
so.. according to (1) πR^2 + πr^2 = 90π
which gives R^2 + r^2 = 90 , only combination that can satisfy would be r = 4 and R= 9 ..hence answer should be A maybe i am missing something..
