1/3 of 60% i.e. 20% females are 75+. However, no information about what percentage are female members of overall number. Insuff.

(2) Exactly 10 male members are over 75 years of age:

Again no information about what percentage are the 10 males members of overall number. Insuff.

(1) & (2) together,
Still the overall number is unknown. Insuff.

Ans: E.

Let there be x males and y females

Statement 1: females over the age of 60 $$= 60%*y=0.6y$$

female over 75 $$= \frac{1}{3}*0.6y=0.2y$$

but we don't know the value of $$x$$ & $$y$$. Hence Insufficient

Statement 2: males over 75 $$=10$$ but nothing mentioned about female. Hence Insufficient

Combining 1 & 2 we have no of member over 75 years $$= 0.2y+10$$. but we don't know about $$y$$. Hence Insufficient

Option E
