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

F.M. in Physics 50.
So, 60% In physics = 30 marks.
30 & above students = 32.
40 & above students = 9 (these 9 students already included in 30 & above group).
So, the answer is 32.

Let me make this simple for everyone.
Total Students : 100.
Let's understand the table from right to left.
For any subject (Chem/Phy).
0 and above : 100 (Includes all students) who scored 0 or more.
10 and above : Includes all students scored 10, 10+ , except previous ones.
20 and above : Includes all students scored 20,20+ except previous ones.
30 and above : Includes all students scored 30,30+ except previous ones.
40 and above : Includes all students scored 40,40+ except previous ones.
Now according to above question;
Students eligible are 32, which includes all the students scored 30,30+
Hence we are not adding another 9 students as they are already included in this column,
It's just they scored more marks than others and listed in leftmost column.

@All.
We have to understand here, that, 30 and above means numbers above 30 i.e., 40 and above are also included here. So 32 students have scored 30 above and out of 30 students, 9 students have scored 40 above.
So the correct answer is 32.

The answer should come 41.
Since 'atleast 60%' means to include the student who scored more then 30 marks,
Which we have 32 stds. Who scored in thirty and 9 stds who scored in fourth,
So, 32 + 9 = 41.
Note: At least, 30 marks means; (greater than 30), which is inclusive of all students who scored from 30 to 50.

Actually, those students who got 30 and above (including those 9stds scoring above 40) are in 60 and above,
See;
30/50 * 100 = 60%
The table shows 32.
