    Question

    Select the option in which the numbers are related in

    the same way as are the numbers of the following sets.   (8, 5, 43) (6, 3, 21)   (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13-Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
    A (7, 4, 30) Correct Answer Incorrect Answer
    B (5, 2, 14) Correct Answer Incorrect Answer
    C (3, 1, 8) Correct Answer Incorrect Answer
    D (9, 2, 25) Correct Answer Incorrect Answer

    Solution

    The logic followed is: (1st number x 2nd number) + (1st number – 2nd number)   = 3rd number. (8, 5, 43) → (8 x 5) + (8 – 5) = 43 → 40 + 3 = 43 (6, 3, 21) → (6 x 3) + (6 – 3) = 21 → 18 + 3 = 21   Now, checking the options:   Option (D): (9, 2, 25) (9 x 2) + (9 – 2) = 25 18 + 7 = 25 25 = 25   Hence, the correct answer is (D).
