Percentage - Excercise 2 - Q26

Question

i. In an examination, 34% of the students failed in Mathematics and 42% failed in English. If 20% of the students failed in both the subjects, then the percentage of students who passed in both the subjects was :

  • 34.00%
  • 44.00%
  • 54.00%
  • 64.00%
4
Answer and Explanation
The Correct answer is : 44.00%
Explanation :
Failed in mathematics, n(A) = 34
Failed in English, n(B) = 42
n(A∪B)=n(A)+n(B)−n(A∩B)=34+42−20=56
Failed in either or both subjects are 56
Percentage passed = (100−56)%=44%
