    Mass box A = x = 10 grams

    Mass box B = y = 5 grams

    Both together = 10 + 5 grams = 15 grams

    Let the mass of the box C be z.

    Mass box C contains One mass box A + one mass Box B.

    i. e.,

    z = x + y

    Given z = 30 grams

    For, x = 10 and y = 5

    30 = 10 + 5

    30 = 15

    Unbalanced.

    For, x = 20 and y = 10

    30 = 2 (10) + 2 (5)

    30 = 20 + 10

    30 = 30

    Balanced.

    30grams = 20grams + 10 grams

    So, 20 g of A and 10g of B would be needed to produce 30 grams of C (Answer)
