    Explanation:

    Correct option:2
    Solution:

    Present Ratio of ages of A and B = 5x: 7x
    According to the question (5x - 5) / (7x - 8) = 5/8
    (5x - 5) * 8 = (7x - 5) * 5
    40x - 40 = 35x - 25
    40x - 35x = 40 - 25
    x = 3
    Present age of A = 5x = 5 * 3 = 15
    Present age of 8 = 7x = 7 * 3 = 21
