Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule /Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (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. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: 749 – 974


Solution : Let's check each option –
First option: 317 – 713; 317 after interchanging the position of first and third digit→713
Second option: 342 – 243; 342 after interchanging the position of first and third digit→243
Third option: 749 – 974; 749 after interchanging the position of first and third digit→947 ≠ 974
Fourth option: 643 – 346; after interchanging the position of first and third digit→346

Therefore, the third option does not follow the same pattern as here the resultant is 947 instead of 974. Hence, the third option is correct.
