    The second number in the given pairs is obtained by

    performing some mathematical operation(s) on the first number. The same operation(s) is/are followed in all the number pairs, EXCEPT one. Find that odd number pair.
    A 48 – 168 Correct Answer Incorrect Answer
    B 22 – 77 Correct Answer Incorrect Answer
    C 62 – 217 Correct Answer Incorrect Answer
    D 74 – 269 Correct Answer Incorrect Answer

    Solution

    Here, we need to find the pattern and get the missing number.   The logic here is: (1st number x 3) + (1st number ÷ 2) = 2nd number. 48 × 3 + (48 ÷ 2) = 168 22 × 3 + (22 ÷ 2) = 77 62 × 3 + (62 ÷ 2) = 217 74 × 3 + (74 ÷ 2) = 259 ≠ 269 Thus, the correct option is 74 – 269. Hence, the correct answer is (D).
