Following table shows the distribution of marks obtained by 2 different set of 100 students who appeared for exams in Mathematics and statistics respectively. Study the table and answer the question.

Marks out of 100 Subject	80 and Above	60 and Above	40 and Above	20 and Above	0 and Above
Mathematics	11	32	70	90	100
Statistics	9	21	64	81	100

The total number of students scoring less than 40% marks in their respective exams are:

Correct option is A

Given:

The distribution of marks obtained by 2 different set of 100 students who appeared for exams in Mathematics and statistics respectively

Solution:

The cumulative frequency is shown in the data.

Number of students scoring above 40% in Mathematics = 70

Number of students scoring less than 40% in Mathematics = 100 -70 = 30

Number of students scoring more than 40% in Statistics = 64

Number of students scoring less than 40% in Statistics =100 -64 = 36

Total number of students scoring less than 40% in both subjects = 30 + 36 = 66
