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)

3333 - 1111

The logic followed here is :

Ist number ÷ 2 = Second number

6666 ÷ 2 = 3333

8888 ÷ 2 = 4444

4444 ÷ 2 = 2222

3333 ÷ 2 =1666.5 ≠ 1111 (odd)
