Answer 2

☆ To find:-

The number of students, secured less than 40 marks.

☆ Now,

You can find it directly but for explanation, Lets convert the given data in less then cumulative frequency distribution.

▪︎ Less than or equal to 10 = 8

▪︎ Less than or equal to 20 = 12+8 = 20.

▪︎ Less than or equal to 30 = 20+20 = 40.

▪︎ Less than or equal to 40 = 40+30 = 70.

▪︎ Less than or equal to 50 = 70+10 = 80.

▪︎ Less than or equal to 60 = 80+10 = 90.

☆ Clearly,

We can see that there are 70 students who secured less than or equal to 40 marks.

☆ Therefore option (a) is correct.
