Correct Answer: 24
Solution : Given: The ratio of the present ages of A and B is 4 : 5
Let A's present age = 4Y and B's present age = 5Y B's age after 5 years will be 35 years. According to the question – ⇒ 5Y + 5 = 35 ⇒ 5Y = 35 – 5 ⇒ 5Y = 30 ⇒ Y = 30 ÷ 5 ⇒ Y = 6 Therefore, A's present age→4Y = 4 × 6 = 24 years
