S10-15 In a certain senior citizens’ club, are more than 1/4 of the members over 75 years of age?

(1) Exactly 60 percent of the female members are over 60 years of age, and, of these, 1/3 are over 75 years of age.
(2) Exactly 10 male members are over 75 years of age.

Official answer is 'E'. Shouldn't the answer be 'C'?

The ans should be e.. the reason being statment 1 says approximately 20% females are 75 yrs or above...

In statement 2 it adds that 10 males are over 75 which is not a percentage figure but an absolute fig. And we dont know the total of Male and female counts and hence we cannot cocme to a conclusion on the percentage..... and hence E
