उत्तर

a. If 40 is the pass marks, then students who got marks less than 40 will be failed.

∴ Number of students who failed = 4

b. Number of students who got marks from 50 to 69

= Number of students who got marks from 50 to 59 + Number of students who got marks from 60 to 69

= 7 + 11

= 18

c. Number of students scored 90 marks and above

= Number of students who scored marks 90 to 92

= 4

d. Number of students who scored marks above 80

= Number of students who score 80 to 89 + Number of students who score 90 to 92

= 6 + 4

= 10

Since, students who scored marks above 80 are given merits.

∴ Number of students who are merit holders = 10

e. Strength of the class = Total number of students who scored different marks 

= 4 + 2 + 7 + 11 + 8 + 6 + 4

= 42
