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

We required only 30 and above so we minus 9 (that is above 40 in physics) from 32 (that is above 30 in physics) we got 23.
Then 23 + 27 = 50. Therefore, 60% of 50 is 30. Above 30, the numbers of students are 32.
So, the answer is 32.
Then 23 + 27 = 50. Therefore, 60% of 50 is 30. Above 30, the numbers of students are 32.
So, the answer is 32.

It is never mentioned that the students who have scored 40 and above are to considered in 30 and above. It may best be a inference. The question should be changed to 'least number of students likely o pursue higher studies in Physics'.

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% ?
We got 30 Answer then see our table we can find 32 come under 30's and above category this is our final answer.

I am too confused on this question. When all the categories are defined separately 30 and above includes 30 to 39 and 40 and above includes 40 to 50. So, How can anyone say 40 and above students are included in 30 and above Column?

It should have been 32 + 9 = 41.
Since it is 30 and above that means even 40 and above students also are supposed to be considered.
30 and above = 32
40 and above = 09
________________
So, total = 41.

(0 - 9)-8; (10 - 19)-12; (20 - 29)-48 - (30 - 39)-23; (40 - 50)-9.
The question says at least 60%, here 60% mark is 30.
30 and above marks column mentioned 23 + 9 = 32 students.
So the answer must be 'option B'.

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.

60% of (total marks)
60% of ?
Then,
60% of 50 marks.
(60/100 * 50),
=30.
That means 30 marks required (60%marks).
Now, see the table and You can see 32 students who have got above 30 in Physics.

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.
