Directions – Question number 41 and 42 are based on the diagram given below:
In a class there are 40 students who play at least one game out of Football, Cricket and Badminton.
Q42. What percentage of students play all the three games?
Correct Answer: D
Question 42 Explanation:
X(μ)= 40
X(μ)= 9+6+8+4+2+7+ X(C ∩ F ∩ B)
40= 36 + X(C ∩ F ∩ B)
X(C ∩ F ∩ B) = 40=36
= 4
According to given data, Percentage of X(C ∩ F ∩ B)
= [ X(C ∩ F ∩ B) / X(μ) ]*100
= (4/40)*100
=10%
