Question

In a school, 40% of the students draw and paint. 40% of those who draw do not paint. If the students do either one of the two, then what % of students paint?

• A. 70
• B. 82.3
• C. 73.33
• D. 50.54

Answer 1

The correct option is C 73.33

Assume the total number of students = 100,
Then the number of students who both draw and paint = 40.
Also, let the number of students who draw = x;
Then the number of students who only draw = 0.4x.

Thus, 0.4x + 40 = x $\Rightarrow$x =66.66
Therefore, number of students who paint = 40 + (100 - 66.66) = 73.33.
