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)

36 - 1266

The logic followed here is :

ist number² = second number

38 - 1444 ⇒ 38² = 1444

44 - 1936 ⇒ 44² = 1936

42 - 1764 ⇒ 42² = 1764

36 - 1266 ⇒ 36² = 1296 ≠ 1266 (odd)
