    Answer: (2) 9405
    Explanation:
    Let the 5 consecutive odd numbers A = X, B = X + 2 , C = X + 4, D = X + 6  & E = X + 8.
    The average of 5 consecutive odd numbers = 95                 (Given in the question)
    Then,  (X + X + 2 + X + 4 + X + 6 + X + 8) /5 = 95
    5 X + 20 = 95 x 5
    5 X = 475 – 20
    5 X = 455
    X = 455 /5
    X = 91

    Then, the value of C = X + 4 = 91 + 4
    = 95

    And the value of E = X + 8  = 91 + 8
    = 99

    Then, the product of C and E = 95 x 99
    = 9405

    Hence, the answer is (2) 9405.
