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. |

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.

Look as the accumulative frequency, as a total number of students is 100. So it adds one over the other then the answer is 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.

@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.
