  1. Question 1

    Q1. The ratio of the ages of A and B is 3:5. After 5 years, the ratio becomes 2:3. What are the present ages of A and B?

    • A) 15, 25
    • B) 20, 30
    • C) 10, 20
    • D) 25, 35

    Answer: 15, 25

    Explanation: Let A's age = 3x, B's age = 5x. After 5 years, (3x + 5) / (5x + 5) = 2 / 3. So, 9x + 15 = 10x + 10, x = 5. Hence, A's age = 3x = 15, B's age = 5x = 25.
