Correct Answer: 9, 5
Solution : Given: The ratio of ages of A and B after 5 years = 7 : 5 Difference between their ages = 4 years Let the ratio of ages of A and B after five years be 7y and 5y According to the question – ⇒ 7y – 5y = 4 ⇒ 2y = 4 ⇒ y = 4 ÷ 2 ⇒ y = 2 Therefore, Present age of A = 7y – 5 = (7 × 2) – 5 = 14 – 5 = 9 years Present age of B = 5y – 5 = (5 × 2) – 5 = 10 – 5 = 5 years
Hence, the third option is correct.
