Question
In the following question, four number pairs are given.
In each pair the number on left side of (-) is related to the number on 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)Solution
The logic followed here is: 2nd number = 11 X 1st number.
25 – 275 = 11 X 25 = 275.
21 – 231 = 11 X 21 = 231.
37 – 407 = 11 X 37 = 407.
44 – 484 = 11 X 44 = 484.
