In a class,95% of the students are present and 2 students are absent.What is the strength of the class?

2 = .05x

x = 40

To find the total strength of the class, we need to calculate the percentage of students who are absent.

Step 1: Calculate the percentage of students present:
Percentage of students present = 100% - Percentage of students absent
Percentage of students present = 100% - 5%
Percentage of students present = 95%

Step 2: Find the total strength of the class:
Let "x" represent the total number of students in the class.

0.95x = Total number of students present
2 = Number of students absent

So, the equation is: 0.95x + 2 = x

Solving for "x":
0.95x + 2 = x
2 = x - 0.95x
2 = 0.05x
x = 2 / 0.05
x = 40

Therefore, the strength of the class is 40 students.

To find the strength of the class, we need to determine the total number of students. Given that 95% of the students are present and 2 students are absent, we can find the total number of students using the following steps:

1. Calculate the percentage of students present: 100% - 95% = 5%. This represents the percentage of absent students.

2. Calculate the number of absent students by converting the percentage to a whole number. If 5% represents 2 students, then we can set up a proportion:

(5% / 100%) = (2 students / X),
where X is the total number of students.

Cross-multiplying the equation, we get:
5% * X = 100% * 2,
0.05 * X = 2,
X = 2 / 0.05.

3. Calculate the value of X:
X = 40.

Therefore, the total strength of the class is 40 students.
