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.

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

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

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.

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

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