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. 45 – 70.
Logic: (1st number ÷ 5) × 8 = 2nd number
90 – 144 → 90 ÷ 5 = 18 × 8 = 144
75 – 120 → 75 ÷ 5 = 15 × 8 = 120
45 – 70 → 45 ÷ 5 = 9 × 8 = 72 (not 70)
65 – 104 → 65 ÷ 5 = 13 × 8 = 104
