Four pairs of numbers have been given, out of which three are alike in some manner, while one is different. Choose out the odd one.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 432 : 324: 231.

Understanding

The pattern follows that the digits of a particular group are the same.

Option 1

Digits 7, 8, 9 are present in all three numbers.

Option 3 

Digits 1, 2, 3 are present in all three numbers.

Option 4

Digits 4, 5, 6 are present in all three numbers.

But in option 2 the pattern doesn't follow.

Hence, option 2 i.e. 432 : 324: 231 is the correct answer.
