Four number pairs have been given out of which three are alike in some manner and one is different. Select the one that is different.
(NOTE: Operations should be performed on the whole number, without breaking down the numbers into their constituent digits. E g. 13-Operations on 13 such as adding (deleting 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.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 29-88.
The logic used here is: (1st number × 3) + 3 = 2nd number
Option 1: 46-141: 46 × 3 = 138, 138 + 3 = 141: This follows the logic.
Option 2: 29-88: 29 × 3 = 87 , 87 + 3 = 90: This does not follow the logic.
