Question

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 1

Answer:

1200

Step-by-step explanation:

The following structure would follow:

Passed candidates in all sections: 5%

Passed none: 5%

Passed candidates in 1 section: 25% of 90% (100% - passed all 5% - passed none 5%) = 22.5%

Passed candidates in 4 sections: 20% of 90% =18%

Passed in 2 sections: 24.5%

Passed in 3 sections: Rest (100 - 5 - 5 - 22.5 - 18 - 24.5) = 25%

But it is given that 300 people passed 3 sections. Hence, 25% = 300.

100% = 1200

Hence, 1200 students must have appeared in the test.
