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 1
The logic followed here Is :
(Ist number )2 + 1 = second number)
24 - 575 = 242 + 1 = 577 ≠ 576 (odd)
14 - 197 = 142 + 1 = 197
12 - 145 = 122 + 1 = 145
18 - 325 = 182 + 1 = 325
