Question

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?

• A. 54 years
• B. 42 years
• C. 52 years
• D. 49 years

Answer 1

Answer:

D. 49 years

Average age of P and Q = 56
So, total age $= (56 \times 2 = 112)$

Ratio = 5 : 3
Total parts = 8

Each part $= (112 \div 8 = 14)$

Age of Q $= (3 \times 14 = 42)$

After 7 years:
(42 + 7 = 49)

Final Answer: 49 years
