Question : Directions: The second number in the given number pairs is obtained by performing certain 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.
Option 1: (7, 89)
Option 2: (8, 102)
Option 3: (5, 60)
Option 4: (6, 76)
Correct Answer: (5, 60)
Solution :
Let's check the options –
First option:
(7, 89); (7 × 12) + (7 – 2) = 84 + 5 = 89
Second option:
(8, 102); (8 × 12) + (8 – 2) = 96 + 6 = 102
Third option:
(5, 60); (5 × 12) + (5 – 2) = 60 + 3 = 63 ≠ 60
Fourth option:
(6, 76); (6 × 12) + (6 – 2) = 72 + 4 = 76
So, the third option does not follow the logic and is different from the others. Hence, the third option is correct.
