Question
Select the option in which the numbers are not related
in the same way as are the numbers of the following set. 68, 84, 42Solution
The pattern followed here is: The sum of the first and second digits of the first number is multiplied by the sum of the first and second digits of the third number to obtain the second number. (68, 84, 42) → (6 + 8) X (4 + 2) = (14 X 6) = 84 (53, 35, 25) → (5 + 3) X (2 + 5) = (8 X 7) = 56 (72, 81, 54) → (7 + 2) X (5 + 4) = (9 X 9) = 81 (34, 35, 23) → (3 + 4) X (2 + 3) = (7 X 5) = 35 (39, 78, 24) → (3 + 9) X (2 + 4) = (12 X 6) = 72 Hence, option D is the answer as it does not follow the given pattern.
