In an examination, 30% and 35% students respectively failed in English and Hindi while 27% students failed in both the subjects. If the number of students passing the examination is 248, find the total number of students who appeared in the examination?
A300
B400
C500
D600
Answer:
B. 400
Read Explanation:
If in an examination x% and y% candidates respectively failed in two different subjects while z% candidates failed in both the subjects, then the percentage of candidates who pass in both subject will be
(100 + Z)- (x + y)
Total number of students passed = (100 + 27) - (30+35) = 62%
According to Question ;
Total Students x 62/100 = 248
Total students = 400
