Five years ago, the average age of p and Q was 25 years. The average age of P, Q, and R today is 25 years. How did will R be after 5 years?

A)20 years

B) 40 year

C) 33 year

D) 50 year

Five years ago, Sum of Age(P and Q) is 50.

At present, Sum of Age(P and Q) would be 60.

The average of Age at present (P, Q, and R) is 25.

that means Sum of Age at present (P, Q, and R) is 75.

P + Q + R = 75

Since P + Q = 60

R = 15

After 5 Years, Age of R would become 20.
