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) are followed in all the number pairs except one. Find that odd number pair.
(NOTE: Operations should be performed on whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/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.)
Option 1: 32 : 99
Option 2: 42 :123
Option 3: 24 : 75
Option 4: 64 : 195

Correct Answer: 42 :123
Solution :
Let's check each option –
First option:
32 : 99→(32 + 1) × 3 = 99
Second
option:
42 : 123→(42 + 1) × 3 = 129 ≠ 123
Third option:
24 : 75→(24 + 1) × 3 = 75
Fourth option:
64 : 195→(64 + 1) × 3 = 195
So, the second option does not follow the same pattern as followed by the other three options. Hence the second option is correct.
