In the following question, four number pairs are given. In each pair the number on left side of (-) is related to the number of the right side of (-) with some Logic/Rule/Relation. Three pairs are similar on basis of 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 its 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)
Answer & explanation
Correct answer: option 3
The logic followed here is :
(Ist number)2 + 1 = IInd number
As
122 + 1 = 145
162 + 1 = 257
142 + 1 = 197 but 193 is given which is odd
102 + 1 = 101
