Question : Directions: In the following question, find the odd number pair from the given alternatives.
Option 1: 28 – 21
Option 2: 31 – 38
Option 3: 45 – 52
Option 4: 64 – 71
Correct Answer: 28 – 21
Solution :
Let's check the options —
First option:
28 – 21→28 – 7 = 21
Second option:
31 – 38→31 + 7 = 38
Third option:
45 – 52→45 + 7 = 52
Fourth option:
64 – 71→64 + 7
= 71
So, in all the options, adding seven to the first number will give the second number except in the first option, which is the odd one. Hence, the first option is correct.
