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: B
Explanation
The correct answer is option 2 i.e. 25 – 7 – 175.
Logic: 1st number × 2nd number - 5 = 3rd number
Except 25 – 7 – 175, all number pairs are following the same pattern.
25 × 7 - 5 = 175 - 5 = 170 (not 175)
