Question
Three of the following four options are alike in a
certain way and thus form a group. Which is the one 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/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)Solution
The logic is followed here- 188 – 128 = 60 x 9 = 540 101 – 92 = 9 x 9 = 81 22 – 12  = 10 x 9 = 90 284 – 266 = 18 x 9 = 108 (Odd one out)
