Question 18

# In the following question, select the odd number pair from the given alternatives.

Solution

The logic here is

22 x 2.5 = 55

26 x 2.5 = 65

30 x 2.5 = 75

38 x 2.5 = 95

In all number pairs except 30 - 85, second number is the product of first number and 2.5.

$$\therefore\$$30 - 85 is the odd number pair among the given number pairs.

Hence, the correct answer is Option C
