Answer 1

$\textbf{\underline{Question :-}}$

Dahihanda village has 500 students in a school. 350 students know to swim, what is the percentage of the students who can swim and who can't swim ??

$\textbf{\underline{Answer :-}}$

70% students know to swim.

30% of students don't know how to swim

$\textbf{\underline{Explanation :-}}$

$\textsf{\underline{Given :}}$

Total Students = 500

Students who know to swim = 350

Students who don't know to swim = 500 - 350 = 150 students.

$\textsf{\underline{To find :}}$

Percentage of students knowing swimming and who don't know swimming.

$\textsf{\underline{Solution :}}$

Percentage of students know swimming =

$\tt{\Rightarrow \dfrac{350}{500} \times 100 }$

$\tt{\Rightarrow \dfrac{350}{5{\cancel{00}}} \times 1 \cancel{00} }$

$\tt{\Rightarrow \dfrac{350}{5} }$

$\tt{\Rightarrow70}$

$\tt{\Rightarrow70\%}$

Therefore 70% students know to swim.

Students who don't know to swim =

$\tt{\Rightarrow100 - 70}$

$\tt{\Rightarrow30\%}$

Therefore 30% of students don't know how to swim

$\therefore$70% students know to swim.

$\therefore$30% of students don't know how to swim
