    Question

    Arjun is seventeenth from the left end of a row of 29 boys and Rahul is seventeenth from the right end in the same row. How many boys are there between them in the row?

    A.

    4

    B.

    5

    C.

    3

    D.

    6

    Correct option is C

    Arjun's position from the left end is 17.
    Rahul's position from the right end is 17, so his position from the left end is:
    29 - 17 + 1 = 13.
    Arjun at position 17 from the left.
    Rahul at position 13 from the left.
    The number of boys between them is the absolute difference between their positions, minus 1:
    Number of boys between them = |17 - 13| - 1 = 4 - 1 = 3.
