Question

Marks of students of a Class are represented in the frequency polygon shown below.



Grade A is given to a student if he got at least 15 marks in the test. How many students got the grade A?

• A. 14

Answer 1

The correct option is A 14
There are two groups who have at least 15 marks in the test, first group is (15-20) and other group is (20-25).

Total number of students who got at least 15 marks is the sum of frequency of both the groups = 8+6 = 14.
