Answer» Correct Answer - Option 2 : Data not sufficient Given: The average of ages of P and Q is 24years. Average age of P, Q and R is 22 years. Formula: If average age of A and B after x years is y, present average age = y - x Calculation: Let the present ages be P, Q and R respectively. (P + Q)/2 = 24 ⇒ (P + Q)= 48 ----(i) (P + Q + R)/3 = 22 ⇒ (P + Q + R) = 66 ----(ii) From above equation we only get the sum of ages but information is not available about time, like present age, after some years and before some years. So, Data not sufficient.

Answer» Correct Answer - Option 2 : Data not sufficient

Given:

The average of ages of P and Q is 24years.

Average age of P, Q and R is 22 years.

Formula:

If average age of A and B after x years is y, present average age = y - x

Calculation:

Let the present ages be P, Q and R respectively.

(P + Q)/2 = 24

⇒ (P + Q)= 48 ----(i)

(P + Q + R)/3 = 22

⇒ (P + Q + R) = 66 ----(ii)

From above equation we only get the sum of ages but information is not available about time, like present age, after some years and before some years.

So, Data not sufficient.
