    Question

    Select the set in which the numbers are related in the same

    way as are the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 25 - Operations on 25 such as adding/ subtracting/ multiplying etc. to 25 can be performed. Breaking down 25 into 2 and 5, and then performing mathematical operations on 2 and 5 is not allowed) (18, 76, 47) (27, 133, 78)
    A (33, 37, 32) Correct Answer Incorrect Answer
    B 14, 198, 94) Correct Answer Incorrect Answer
    C (32, 44, 32) Correct Answer Incorrect Answer
    D (72, 86, 79) Correct Answer Incorrect Answer

    Solution

    The logic followed here is: 3rd number = (1st number + 2nd number) ÷ 2

    (18, 76, 47) → (18 + 76) ÷ 2 = 94 ÷ 2 = 47

    (27, 133, 78) → (27 + 133) ÷ 2 = 160 ÷ 2 = 80

    (33, 37, 32) → (33 + 37) ÷ 2 = 70 ÷ 2 = 35 ≠ 32

    (14, 198, 94) → (14 + 198) ÷ 2 = 212 ÷ 2 = 106 ≠ 94

    (32, 44, 32) → (32 + 44) ÷ 2 = 76 ÷ 2 = 38 ≠ 32

    (72, 86, 79) → (72 + 86) ÷ 2 = 158 ÷ 2 = 79.
