Question
Four number-pairs have been given, out of which three
are alike in some manner and one is different. Select the number-pair that is different from the rest.Solution
For the number pairs: 21 × 6 - 6 = 120 27 × 6 - 6 = 156 33 × 6 - 6 = 192 But for 19, 19 × 6 - 6 = 108 (not 100, so it does not follow the pattern). Thus, 19, 100 is the odd one out.
