Answer 2

Answer:

Total number of students = 200

Step-by-step explanation:

From the question it is given, % of girls =45%

Number of boys =110

The percentage of boys can be calculated by subtracting the percent of girls from the total percent.

Percentage of boys in school = 100 - percentage of girl in school

⇒100−45

⇒55%

According to the question given,

Number of boys in school =110

Let total number of students in school =x

⇒55÷100 × x=110

Here we convert the percentage and re-write the above equation as follows.

⇒55÷100 × x=110

Here we will send the terms in the left hand side of the equation to the right hand side of the equation. So the equation will be reduced as follows.

⇒x=110×100÷55

⇒x=200

Therefore total number of students in school ⇒x=200
