Answer 2

➤ Given :-

Total children in school :- 800

Total children playing :- 200

Total children writing :- 400

Percent of children reading :- 25%

➤ To Find :-

• Percent of children playing.
• Percent of children writing.
• Number of children reading.

➤ Solution :-

Percent of children playing :-

${\tt \longrightarrow \dfrac{200}{800} \times 100}$

${\tt \longrightarrow \dfrac{200}{ \cancel{800}} \times \cancel{100} = \boxed{\tt \dfrac{200}{8} \times 1}}$

${\tt \longrightarrow \dfrac{200 \times 1}{8} = \dfrac{200}{8}}$

${\tt \longrightarrow \cancel \dfrac{200}{8} = \boxed{\tt 25 \bf\%}}$

Percent of children writing :-

${\tt \longrightarrow \dfrac{400}{800} \times 100}$

${\tt \longrightarrow \dfrac{400}{\cancel{800}} \times \cancel{100} = \boxed{\tt \dfrac{400}{8} \times 1}}$

${\tt \longrightarrow \dfrac{400 \times 1}{8} = \dfrac{400}{8}}$

${\tt \longrightarrow \cancel \dfrac{400}{8} = \boxed{\tt 50 \bf\%}}$

Number of children reading :-

${\tt \longrightarrow 25 \bf\% \sf \: \: of \tt \: \: 800}$

${\tt \longrightarrow \dfrac{25}{100} \times 800}$

${\tt \longrightarrow \dfrac{25}{ \cancel{100}} \times \cancel{800} = \boxed{\tt 25 \times 8}}$

$\tt \longrightarrow 200 \sf \: children$

$\:$

${\sf\large\red{\underbrace{\sf Therefore :-}}}$

• Percent of children playing is 25 ${\bf\%}$
• Percent of children writing is 50 ${\bf\%}$.
• Number of children reading is 200 children.
