Correct Answer - Option 4 : 40
Ration of Present age of P and Q = 2 : 3
Assume;
Age of P = 2P
Age of Q = 3P
Eight years ago;
Age of P = (2P - 8) years
Age of Q = (3P - 8) years
Age of P = Q/2
⇒ (2P - 8) = (3P - 8)/2
⇒ 2 × (2P - 8) = (3P - 8)
⇒ 4P - 16 = 3P - 8
⇒ 4P - 3P = 16 - 8
⇒ P = 8
So,
Age of P = 2P = 16 years
Age of Q = 3P = 24 years
Sum of age of P and Q = 16 + 24
= 40 years
Hence, "40" is the correct answer.
