    Question

    If 1 is subtracted from each odd digit and 2 is added to each even digit in the number '2965413'. What will be the average of the largest and smallest digits thus formed?

    A.

    8

    B.

    2

    C.

    6

    D.

    4

    Correct option is D

    Given: 2965413
    Subtract 1 from each odd digit:
    9 - 1 = 8; 5 - 1 = 4; 1 - 1 = 0; 3 - 1 = 2
    Add 2 to each even digit:
    2 + 2 = 4; 6 + 2 = 8; 4 + 2 = 6
    So, the number formed is '4884602'.
    The largest digit is 8, and the smallest digit is 0.
    Average = (8 + 0) ÷\div 2 = 8 ÷\div 2 = 4
    So, the correct answer is (d).
