In an examination, questions were asked in five sections. Out of the total students, 5% candidates cleared the cut-off in all the sections and 5% cleared none. Of the rest, 25% cleared only one section and 20% cleared four sections. If 24.5% of the entire candidates cleared two sections and 300 candidates cleared three sections. Find out how many candidates appeared at the examination?
Answer & Solution
Correct Answer:
Option
B
Passed in none = 5%
Passed in all = 5%
Passed in four = 20% of 90% = 18%
Passed in one = 25% of 90% = 22.5%
Passed in two = 24.5%
Passed in three = (100 - 5 - 5 - 22.5 - 24.5 - 18) = 25%
But given 300 students passed in three
Hence, 25% = 300
So, 100% = 1200
1200 students must have appeared
