Question
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)Solution
The logic followed here is: The second number is obtained by subtracting 6 from the five times of the first number. 24 - 114 → 5 X 24 - 6 = 114 45 - 219 → 5 X 45 - 6 = 219 63 - 309 → 5 X 63 - 6 = 309 37 - 182 → 5 X 37 - 6 = 179 ≠ 182
