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

I think it must be 41.

Friends, 32 is correct answer. It's sum of 40 and 30. See below calculation:
40 and above: 9 - 0 = 9
30 and above: 32 - 9 = 23
20 and above: 80 - 32 = 48
10 and above: 92 - 80 = 12
0 and above: 100 - 92 = 8
Total Student = (9 + 23 + 48 + 12 + 8) = 100 student.
So, 32 is a sum of 40 and 30 (and above) students who got at least 60% marks in Physics.
40 and above: 9 - 0 = 9
30 and above: 32 - 9 = 23
20 and above: 80 - 32 = 48
10 and above: 92 - 80 = 12
0 and above: 100 - 92 = 8
Total Student = (9 + 23 + 48 + 12 + 8) = 100 student.
So, 32 is a sum of 40 and 30 (and above) students who got at least 60% marks in Physics.

32 is right answer because it ask at least 30 n above here 30 is also included in 40 and above 30 not included.

Can anybody explain to me how we got 32, 60 can come under 40 so why we took 30?

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.

Friends, 32 is correct because look at the chart it is mentioned that "30 and above" i.e. all the students whose marks are between 30 - 50 are already included in it. Had it been 30 - 40 and then 40 - 50 then we should have considered 32 + 9 = 41.
Hope you get it.
Hope you get it.

(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'.

We should have to calculate the number of students who got 40 and above also. Am I right?
Kamini choudhary said:

I also agree with 41.
Because at least meant 60 %. Thats mean we should include also 40 and above. If I'm wrong, please correct me.
