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)

12 - 50

Except 1 all are following the below pattern

(Ist number × 4) + 4 = second number

12 - 50 = (12 × 4) + 2 = 52 (odd)

8 - 36 = (8 × 4) + 4 = 36

10 - 44 = (10 × 4) + 4 = 44

18 - 76 = (18 × 4) + 4 = 76
