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 |

What is the different between the number of students passed with 30 as cut-off marks in Chemistry and those passed with 30 as cut-off marks in aggregate?
Answer: Option
Explanation:
Required difference
= (No. of students scoring 30 and above marks in Chemistry)
- (Number of students scoring 30 and above marks in aggregate)
= 27 - 21
= 6.

Actually the answer will be -6, if we subtract the values (21- 27) answer will be - 6.

6 is the correct answer. Because 30 above means included 40 to 50. So we don't need re-added 40 above.

If cut-off point is above 30.
Why only taken as above 30. And why not above 40 is also added?
Anyone, please explain.

9 should be the right answer.
It is said about 30 as cut off so above this all will be added.

@Rajesh.
You are correct and the given answer also correct because in the question given that 30 and above means the number of student get 40 and above also included in 30 and above.
And observe that the number of students values goes to decrease in the order (0 and above), (10-and above), (20-and above).
So the number of student obtained 30 and above aggregate marks is 27 and number of students obtained marks 30 and above are 21 in chemistry.
The difference is 27-21 = 6.

In the question, it is given that 30 as the cut-off mark which means 30 and above but if we take the range 40 and above then no of the students who obtained the exact 30 may not fall under the 40 and above category.

6 is the right answer because the students scoring higher marks are included in 21 and 27. If they hadn't been included the total would have been 100 after adding the students of all the categories.
