    Question

    The weights of 3 boxes are 4, 5 & 11 kilograms. Which of the following CANNOT be the total weight, in kilograms, of any combination of these boxes?

    A.

    15

    B.

    16

    C.

    20

    D.

    17

    Correct option is D


    Weight of boxes → 4, 5, 11 kg
    Possibility of adding two or more weight
    4 + 5 = 9 kg
    4 + 11 = 15 kg
    5 + 11 = 16 kg
    4 + 5 + 11 = 20 kg
    Hence, 17 cannot be obtained.
