Question

The average age of P, Q and R is 25 years. If the total age of P and Q together is 39 years, then R’s age is:
1. 19 years
2. 22 years
3. 28 years
4. 36 years

Answer 1

Correct Answer - Option 4 : 36 years

Given:

Average age of P, Q and R is 25 years.

The total age of P and Q together is 39 years

P + Q = 39

Formula:

Average = sum of data / number of data

Calculations:

⇒ (P + Q + R)/3 = 25

⇒ P + Q + R = 75

⇒ 39 + R = 75

⇒ R = 36 years

∴ R’s age is 36 years.
