Answer 1

Answer:

312 boys

Step-by-step explanation:

let x ne the total no of students

x=468x100/ 60

x=780

40/100x780 = 312

Answer 2

Answer:

$\star\: \textbf{There\: are}$ $\bf\green{312\: boys}$ $\bf{in \: school}$

Given:-

• Boys in school = 40%
• Girls in number = 468

To find:-

• Boys in number = ?

There are 40% boys in the school.

$\therefore$ There are (100-40)% = 60% girls in the school.

${\underline{\bf\red{ATQ:- }}}$

$\implies\sf 60\% = 468 \\\\\\\implies\sf 1\% = \dfrac{468}{60} \\\\\\\implies\sf 100\% = \dfrac{468 \times 100}{60} \\\\\\\implies{\boxed{\bf\green{100\% = 780 }}}$

$\therefore\sf{There\: are }$ $\sf\green{780\: students}$ $\sf{in \: the \: class}$

$\rule{200}{1}$

$\sf Now, Total\: students = Number\: of \: boys + Number\: of \: girls \\\\\Rightarrow\sf Number\: of \: boys = 780 - 468 \\\\\Rightarrow{\boxed{\sf\green{Number \: of \: boys = 312}}}$

$\therefore\bold{There \: are \: 312 \: boys \: in \: school}$
