Hint:

### 1. When a certain quantity is divided into 100 equal parts and a certain part of it is to be expressed in terms of the whole quantity, that portion is called as a percent, represented with a % sign.

2. Percentage students who completed essay by due date = number of students who completed essay by due date / Total students * 100.

## The correct answer is: 21

### Given-

Percentage students who completed essay by due date = 70%

Total students = 30

To find-

Number of students who completed essay by due date

Solution-

We know that-

Percentage students who completed essay by due date = number of students who completed essay by due date / Total students * 100

∴ 70 * 30 / 100 = number of students who completed essay by due date

∴ 21 = number of students who completed essay by due date

Final Answer- Option 'c' i.e. '21' is the correct answer to the given question.
