The difference between 38% and 22% of a number is 3200. What is 31/2% of that number?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 3100

Application

Let, the number is n

(38 - 22)% of n = 16% of n

So,

16% of n = 3200

Hence,

31/2% of n = 3200/16 × 31/2

= 100 × 31

= 3100
