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 -Operators 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)

5555 - 7777

The logic followed here is :

Ist number × 2 = second number

3333 × 2 = 6666

4444 × 2 = 8888

2222 × 2 = 4444

5555 × 2 = 11110 but 7777 is given which is odd
