The following table shows the classification of 100 students based on the marks obtained by them in Maths and Science in an examination.

Subjects	Marks out of 100
	80 and above	60 and above	40 and above	20 and above	0 and above
Maths	12	35	80	94	100
Science	16	43	76	88	100
Average (Aggregate)	14	39	78	91	100

What is the difference between the number of students who passed with 60 as cut-off marks in Science and those who passed with 60 as cut-off marks in aggregate?

The correct answer is 4.

To find the difference between the number of students who passed with 60 as cut-off marks in Science and those who passed with 60 as cut-off marks in aggregate, we analyze the values given in the table:

1. Number of students scoring 60 and above in Science:
Locating the row labeled Science and looking under the column 60 and above, we find that 43 students scored 60 or above.

2. Number of students scoring 60 and above in Aggregate:
Locating the row labeled Average (Aggregate) and looking under the column 60 and above, we find that 39 students scored 60 or above.

Now, compute the difference between the two numbers:

$\text{Required Difference}=43-39=4$

Therefore, the difference between the number of students who passed with 60 as cut-off marks in Science and in aggregate is 4.
