Question 3 of 5
3. Question
In an examination 30% and 35% students respectively failed in History and Geography 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.
Correct
Answer : c
Percentage of students passing the examination = ( 100 – ( 30 + 35 – 27 ) %
[ here , x = 30, y = 35 and z = 27 ]
= ( 100 – 38)% = 62%
Let the number of students appearing in the examination be x
Given : 62% of x = 248
Or, 62/100*x = 248 or x = 248*100/62 = 400
Therefore, 400 students appeared in the examination.
