विद्यार्थियों की संख्या बताइए।
​

Answer 1

Answer:

let the total no of students be x

percent of absent students=100-97=3%

3%of x=18

3x=18 ×100=1800

x=1800÷3=600

hence the no of students is 600

Answer 2

Total number of students in the class was 600.

Step-by-step explanation:

Let the number of students in the class is x.

It has been given that 97% students are present.

In other words, we can say that 3% student are absent.

So, mathematically, the number of absent student is given by 0.03 x

Now, the number of absent student is 18.

Hence, we have the equation,

0.03 x = 18

Multiply both sides by 100

3x = 1800

Divide both sides by 3

x = 600

Therefore, total number of students in the class was 600.
