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
11 - 1331 ⇒ 113 = 1331
12 - 1728 ⇒ 123 = 1728
16 - 4086 ⇒ 163 = 4096 ≠ 4086
13 - 2197 ⇒ 133 = 2197
