Question
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.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).
