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.)
- A.
36 – 84
- B.
72 – 168
- C.
66 – 154
- D.
33 – 72

Show answer & explanation
Correct answer: D
To find the odd one out, we must examine the mathematical relationship between the two numbers in each pair.
Analyzing the Pairs
We are looking for a consistent ratio or operation applied to the first number to get the second. Let's test the ratio of the second number to the first for each option:
Option 1: 36 – 84
Ratio: 84 / 36 = 2.33 (or 7/3)
Option 2: 72 – 168
Ratio: 168 / 72 = 2.33 (or 7/3)
Option 3: 66 – 154
Ratio: 154 / 66 = 2.33 (or 7/3)
Option 4: 33 – 72
Ratio: 72 / 33 = 2.18 (or approximately 24/11)
