Three of the following numbers are alike in a certain way and one is different. Pick the odd one out.
(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 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15 – 450.
Logic: (First number × 3) × First number = Second number
Except "15 – 450", all number-pairs follow the same logic.
15 – 450 → (15 × 3) × 15 = 45 × 15 = 675 ≠ 450
