Question

in a school 3 upon 5 of the students are girls if the number of boys in the school is 200 find total number of students in the school​

Answer 1

Answer:

Let the total number of students be x

then

no.of girls = 3x/5

no. of boys = 200

Now

total students = no.of girls + no. of boys

=> x = 3x/5 + 200

=> x = (3x+1000)/5

=> 5x = 3x+1000

=> 5x-3x = 1000

=> 2x = 1000

=> x = 1000/2

=> x = 500

Hence the total number of students are 500

I hope this will help you!!!!!

Answer 2

$\huge\bold\green{\underline{Solution:}}$

$\large{\underline{\red{\rm{Let:}}}}$

The total number of students be X

$\large{\underline{\red{\rm{Given:}}}}$

The number of boys=200

The number of girls=3/5X

$\large{\underline{\red{\rm{To\: Find:}}}}$

Total number of students in school

$\large{\underline{\purple{\rm{A.T.Q:}}}}$

$\{The\:sum\:of\:boys\:and\: girls=Total\: Students\\ \\ \implies 200+\frac{3x}{5}=x\\ \\ \implies 200=x-\frac{3x}{5}\\ \\ \implies 200=\frac{5x-3x}{5}\\ \\ \implies 2x=1000\\ \\ \implies 2x=1000\\ \\ \implies x=500}}$

Hence,

The number of girls=3/5×500=300

The total number of students=500

$\large{\underline{\red{\rm{AnswEr:}}}}$

$\large{\boxed{\green{\rm{The\: number\:of\: girls=300:}}}}$

$\large{\boxed{\purple{\rm{The\: number\:of\: total\:students=500:}}}}$
