Question

There are 2500 children in a school. If 45% of them are boys, find the number of boys and girls in the school
​

Answer 1

Answer:

Step-by-step explanation:

We are given that 45% of the students in a school are boys

So, percentage of girls = 100% - 45% = 55%

Let the total no. of students in school be x

So, No. of girls = 55\%x = 0.55x55%x=0.55x

We are given that number of girls is 1100

So, \begin{gathered}0.55x=1100\\x=\frac{1100}{0.55}\\x=2000\end{gathered}

0.55x=1100

x=

0.55

1100

x=2000

No. of boys = 2000-1100 = 900

Hence There are 900 boys
