Question
Three of the following four options are alike in a
certain way and thus form a group. Which is the option that does NOT belong to that group? (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding /deleting /multiplying etc., to 13 can be performed. Breaking down 13 into and 3 and then performing mathematical operations on 1 and 3 is not allowed) .Solution
In each option, 2nd number = 3 X 1st number, 3rd number = 2nd number + 32 In option 'A', '14, 42, 74' → 3 X 14 = 42, 42 + 32 = 74 In option 'B', '11, 33, 65' → 3 X 11 = 33, 33 + 32 = 65 In option 'C', '35, 105, 135'→ 3 X 35 = 105, 105 + 32 = 137 ≠ 135 In option D, '54, 162, 194' → 3 X 54 = 162, 162 + 32 = 194.
