Study the given following table carefully and answer the following question.
What is the difference 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?| Subjects (Full Marks 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 |
| Aggregate | 7 | 27 | 73 | 87 | 100 |
Step-by-step Solution:
The phrase "passed with 30 as cut-off marks" means scoring 30 or more. By looking at the "Chemistry" row and the "30 and above" column in the table, we find the number is 21.
Similarly, at the intersection of the "Aggregate" row and the "30 and above" column, the number is 27.
Finally, we find the difference between the two values.
27 (Aggregate) - 21 (Chemistry) = 6
Final Answer: The difference is 6.
