Directions to Solve
Study the following table and answer the questions.
Classification of 100 Students Based on the Marks Obtained by them in Physics and Chemistry in an Examination.
| Subject | Marks out of 50 | ||||
| 40 and above | 30 and above | 20 and above | 10 and above | 0 and above | |
| Physics | 9 | 32 | 80 | 92 | 100 |
| Chemistry | 4 | 21 | 66 | 81 | 100 |
| Average (Aggregate) | 7 | 27 | 73 | 87 | 100 |
2.
If at least 60% marks in Physics are required for pursuing higher studies in Physics, how many students will be eligible to pursue higher studies in Physics?
Answer: Option
Explanation:
| We have 60% of 50 = |  |
60 | x 50 |  |
= 30. |
| 100 |
Required number
= No. of students scoring 30 and above marks in Physics
= 32

As minimum qualify marks is 30 so we can take 30 and above as well 40 and above. Why is taken only 30 and above? Please reply.

First of all I got the doubt that, why 40 and above were not included in the answer but later I came to know by above comments that, they were already included in 30 and above.
So, if that's true then whats the need to add 40 and above column in the table.

Friends please just think what is given main point is that 30 and above means included all the students got marks more than 40 also.
So answer is 100% correct there is no doubt.

@Amruta.
Total mark given is 50.
As we have to calculate percentage, we have to convert it to 100.
Students having at least 60% are eligible for higher studies.
i.e. 60/100=30/50.
i.e. Students who got at least 30 marks in physics are eligible to perform higher studies.
Look at the table for number of students who got 30 and above in physics.
Clearly the answer is 32.

I am not understand how you take 60% of 50?
Ankit said:

30 marks and above include 40 marks and above, and we don't know how many of students who got 30 marks and above, also have 40 and above, so we can only find least number of people eligible so, Answer should be 32.

This question has asked that how many students will be able to pursue higher study in physics. Thus, students who are getting 60% and above it are considered for higher study. So, it has to be 41.

If we can assume 50 as 100% so our 1st step is 1st calculate the percentage of 50 how much see below it.
50 100
60% ?
We got 30 Answer then see our table we can find 32 come under 30's and above category this is our final answer.
50 100
60% ?
