Question
In a school, 40% of the students draw and paint. 40% of those who draw do not paint. If the students do one of the two, then what % of students paint?
Answer: Option C
:
C
If we 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 => x= 66.66
Therefore, number of students who paint= 40+(100-66.66)= 73.33. Answer is option (c)
