Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.

Show answerHide answer

Correct answer: (D) 22 - 97

Explanation

In every other pair the second number is 4.5 times the first (16 × 4.5 = 72, 24 × 4.5 = 108, 18 × 4.5 = 81). 22 × 4.5 = 99, not 97, so 22 - 97 is the odd one.
