Question : Directions: Four number-pairs have been given, out of which three are alike in some manner and one is different. Select a different one.
(NOTE: Operations should be performed on the 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 2: 5 : 134

Option 3: 9 : 720

Correct Answer: 5 : 134


Solution : Let's check each option –
First option: 7 : 334; 7 3 – 9 = 343 – 9 = 334
Second option: 5 : 134; 5 3 – 9 = 125 – 9 = 116 ≠ 134
Third option: 9 : 720; 9 3 – 9 = 729 – 9 = 720
Fourth option: 11 : 1322; 11 3 – 9 = 1331 – 9 = 1322

So, only the second option doesn't follow the same pattern as followed by the given set of numbers. Hence, the second option is correct.
