Study the bargraph and answer the following questions:

(a) If 40 is the pass mark, then how many students have failed?

(b) How many students got marks from 50 to 69?

(c) How many students scored 90 marks and above?

(d) If students who scored marks equal to or above 80 are given merits then how many merit holders are there?

(e) What is the strength of the class?

Answer 1

(a) Number of students scored marks below 40 i.e., 30-39 ate 4 . 4 students have failed.

(b) Number of students got marks from 50 to 59 is 7 and number of students got marks from 60 to 69 is 11.

∴ 7 + 11 = 18 students got marks from 50 to 69.

(c) 4 students scored marks from 90 and above.

(d) Number of students got marks from 80 to 89 is 6. Number of students got marks from 90 to 92 is 4.

∴ 6 + 4 = 10 students are merit holders.

(e) Total number of students in the class = 4 + 2 +7 + 11 + 8 + 6 + 4 = 42
