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?

Here 30 and above means 30-50 ie.40 and above data is also included in the 30 and above data.so during calculation if one will include 40 and above data.It means 40 and above data included twice and thus the answer will be wrong.
If the data would have been 30-40 and 40-50 separately then including both the data would have been the correct step.

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.

Why 40 and above is considered?

The Correct answer is 32. Because 32 and above means it also included 40 and above. O and 100 include 100 students.

It clearly states at least 60%. So the answer should be 41.

60% and above means already 30 Marks and above includes 40 and above so answer was correct.

But 40 will also be included in cut off 30.
So, the answer will be 32+9=41.
So, the answer will be 32+9=41.
