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

Can anyone tell me from where 50 came. I am totally new in solving DI.

If we look carefully at the word structure given to us, it clearly states that ‘ at least’ 60% of the score must be obtained to pursue a higher grade in Physics.
In the case that the question stated accumulative data, then the correct answer would have been 32.
However, the word choice and framing of the question remain vague.
Thus, the answer can be both 41 and 32.

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.

(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'.

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.

Yes, the answer should be 41.

It may be 32+9=41.
Because at least 60%.
Because at least 60%.

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

I think it must be 41.
