The average of the present ages of P and Q is 56 years, and their ages are in the ratio 5:3. What will be the age of Q seven years hence?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 49 years.
According to the question,
⇒ 5x + 3x = 56 × 2
⇒ 8x = 112
⇒ x = 14
Age of Q seven years hence = 3x + 7
⇒ 3 × 14 + 7 = 42 + 7 = 49 years
