May be it should have been 9. Right? the students who got 40 and above should have been counted.

9 should be the right answer.

It is said about 30 as cut off so above this all will be added.

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

30 as cut-off means minimum should be 30.

As we have values directly.

Calculate it.
Gurvinder said:   1 decade ago
If cut off is 30, it means marks with 40 and above 40 are also be added.
