Three of the following four 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 1and 3 is not allowed)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 33-97
Logic: 1st number× 3 = 2nd number
38 × 3 = 114; 41 × 3 = 123; 25 × 3 = 75; 33 × 3 = 99 ≠ 97
All follow the same logic except option 4.
