    Question

    The average of 7 consecutive numbers is 33. The greatest of these numbers is:

    A.

    30

    B.

    28

    C.

    36

    D.

    33

    Correct option is C

    Given:

    - The average of 7 consecutive numbers is 33.

    Concept Used:

    Let the 7 consecutive numbers be x, x+1, x+2, ..., x+6.

    The average of these numbers is given by:

    Average = (x+(x+1)+(x+2)+...+(x+6))7=33\frac{ (x + (x+1) + (x+2) + ... + (x+6)) }{ 7 }= 33​​

    Solution:

    The sum of the 7 consecutive numbers is 7 times the average:

    Sum = 7 × 33 = 231

    The sum of the numbers is also given by:

    7x + (0 + 1 + 2 + 3 + 4 + 5 + 6)

    The sum of the numbers 0 to 6 is (6 × 7) / 2 = 21.

    So, the sum is:

    7x + 21 = 231

    7x = 231 - 21 = 210

    x = 210 / 7 = 30

    The greatest of these 7 numbers = 30 + 6 = 36

    The greatest of these 7 consecutive numbers is 36.
