(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:

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
