Answer 2

➤ Given :-

Total students in school :- 700

Percent of students like cricket :- 20%

Percent of students like football :- 40%

➤ To Find :-

Number of students like to play hockey............

➤ Solution :-

First, we should find the number of children like to play football and cricket in numerical format.....

Number of students like cricket :-

${\tt \longrightarrow 20 \bf\% \sf \: \: of \: \tt \: 700}$

${\tt \longrightarrow \dfrac{20}{100} \times 700}$

${\tt \longrightarrow \dfrac{20}{\cancel{100}} \times \cancel{700} = \boxed{ \tt 20 \times 7}}$

$\tt \longrightarrow 140 \sf \: \: students$

Number of students like football :-

${\tt \longrightarrow 40 \bf\% \sf \: \: of \tt \: \: 700}$

${\tt \longrightarrow \dfrac{40}{100} \times 700}$

${\tt \longrightarrow \dfrac{40}{ \cancel{100}} \times \cancel{700} = \boxed{ \tt 40 \times 7}}$

${\tt \longrightarrow 280 \sf \: \: students}$

Now, we should add the obtained answers and then subtract it from the total number of students.........

${\tt \longrightarrow 700 - (140 + 280)}$

$\tt \longrightarrow 700 - 420$

${\tt \longrightarrow 280 \sf \: \: students}$

$\Huge\therefore$280 students like to play hockey.
