The difference between the 38% of a number and 22% of that number is 3200. What is the $15\frac{1}{2}\%$ of that number?
Answer & explanation
Correct answer: option 1
Let number = 100x
According to the question ,
38% of 100x - 22% of 100x= 3200
16x = 3200
100x = 20,000
Now,
$15\frac{1}{2}\%$ of 20,000 = 20,000 × \(\frac{31}{200}\) = 3100
