    If John has x marbles, Jivanti will have 45-x marbles.

    If both of them lost 5 marbles each, John will have x-5 and Jivanti will have 45-x-5 ie 40-x

    Product of the number of marbles left is 124

    (x-5) (40-x) = 124

    x^2-45x+324=0

    x^2-36x-9x+324=0

    (x-36) (x-9) = 0

    x=36 or 9

    The number of marbles with them is 36 and 9
