Answer 1

Answer:

$\boxed{\sf Total \: number \: of \: girls \: in \: class = 32}$

$\boxed{\sf Total \: number \: of \: boys \: in \: class = 8}$

Given:

Total number of students in class = 40

Total number of girls in class = $\sf \frac{4}{5}$ × Total number of students in class

To Find:

The number of boys and girls in the class

Step-by-step explanation:

$\sf \implies Total \: number \: of \: girls \: in \: class \\ \ \ \ \ \ \ \ \ \ \ \sf = \frac{4}{5} \times Total \: number \: of \: students \: in \: class \\ \\ \ \ \ \ \ \ \ \ \ \ \sf = \frac{4}{5} \times 40 \\ \\ \ \ \ \ \ \ \ \ \ \ \sf = \frac{4}{ \cancel{5}} \times \cancel{5 }\times 8 \\ \\ \ \ \ \ \ \ \ \ \ \ \sf = 4 \times 8 \\ \\ \ \ \ \ \ \ \ \ \ \ \sf = 32$

$\sf \implies Total \: number \: of \: girls \: in \: class + Total \\ \sf number \: of \: boys \: in \: class = Total \: number \: \\ \sf of \: students \: in \: class \\ \\ \sf \implies 34 + Total \: number \: of \: boys \: in \: class = 40 \\ \\ \sf \implies Total \: number \: of \: boys \: in \: class = 40 - 32 \\ \\ \sf \implies Total \: number \: of \: boys \: in \: class = 8$

$\huge\bold{\mathtt{\fcolorbox{Black}{Pink}{ANSWER}}}$

${\red\bigstar\large\bold{\mathrm{\orange{\underline{Given:}}}}}$

☯ $\sf Total\:number\:of\:students\:=\:40$

☯ $\sf Girls\:=\: \dfrac{4}{5}\: of\:40$

${\red\bigstar\large\bold{\mathrm{\orange{\underline{To\:Find:}}}}}$

☯ $\sf Total\:number\:of\:girls\:and\:boys$

${\red\bigstar\large\bold{\mathrm{\orange{\underline{Solution}}}}}$

➡ $\sf Total\:Number\:of\:girls\:=\: \dfrac{4}{5} \times 40$

➡ $\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\: 4 \times \cancel\dfrac{40}{5}$

➡ $\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\: 4 \times 8$

➡ $\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\: 32$

✴ $\large\bold{\boxed{\mathtt{\red{No.\:of\:girls\:=\:32}}}}$

$\sf Now, \:number\:of\:boys\:will\:be\: \\ \sf \:=\:Total\:Students\:-\:No.\:of\:girls$

▶ $\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\: 40\:-\:32$

▶ $\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\: 8$

✴ $\large\bold{\boxed{\mathtt{\red{No.\:of\:boys\:=\:8}}}}$
