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)

2125 - 8600

The logic followed here is :

Ist number × 4 = IInd number

3375 × 4 = 13500

2125 × 4 = 8500 but 8600 is given that's why it is odd

2685 × 4 = 10740

1595 × 4 = 6380
