Question

There are 600 pupils in a school. The ratio of boys to girls in this school is 3:5. How many girls and how many boys are in this school?

​

Answer 1

$\huge{ \underline{ \bf{Given \: : }}}$

• Total number of pupils is 600
• ratio of boys and girls is 3 : 5

$\huge{ \underline{ \bf{To \: find \: : }}}$

• Numbers of boys and girls

$\huge{ \underline{ \underline{ \mathrm{Solution \: : - }}}}$

Let the numbers of boys and girls be

• 3x and 5x

As we know the total number of pupils in a school is 600

$\\ \tt \to600 = 3x + 5x$

$\\ \tt \to8x = 600$

$\\ \tt \to \: x = \cancel\frac{600}{8}$

$\\ \tt \to \: x = 75$

Now,

• 3x = 3(75) = $\red{225}$
• 5x = 5(75) = $\red{375}$

Therefore, the number of boys is 227 and number of girls is 375.

Answer 2
