Answer 1

let the total no. of students be x
boys %=100%-40%=60%
60% of x=600
60/100*x=600
x=(600*100)/60
x=60000/60
x=1000
Girls=(1000*40)/100
=40000/100
=400girls

Answer 2

Concept Introduction: Percentage is a concept in Mathematics that is used everywhere.

Given:

We have been Given:

$40\%$

of students is girls and number of Boys is

$600$

To Find:

We have to Find: find the number of girls in the school and also find the total number of the students in the school.

Solution:

According to the problem, Let the total no. of students be

$x$

Therefore total percentage of boys is

$100 - 40 = 60\%$

therefore

$60\% \: of \: x = 600 \\ \frac{60x}{100} = 600 \\ x = \frac{600 \times 100}{60} = 1000$

Total number of students is

$1000$

therefore the number of girls is

$1000 - 600 = 400$

Final Answer: The total number of students is

$1000$
