In the following question, four number pairs are given. In each pair the number on left side of (-) us 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)
5 is added to the square of the first number to get the second number. 1) 43 - 1854→ 43² + 5 = 1849 + 5 = 1854. 2) 36 - 1301→ 36² + 5 = 1296 + 5 = 1301. 3) 24 - 581→ 24² + 5 = 576 + 5 = 581. 4) 18 – 332→ 18² + 5 = 324 + 5 = 329.
