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

(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 'option B'.

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.

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.

Why 40 and above is considered?

I think the Answer is 41. Marks above 40 must be considered.

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.
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.

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