Question

in a group of 50 children 11 cannot swim what percentage can swim​

Answer 1

total children=50

children that cannot swim=11

percentage of children's who cant swim =

childrens who cant swim

total children's

= 11 ×100 =

$11 \times 100 \div 50 = 22$

Now, there are 22 % students who cant swim

and we know that the basic unit of percentage Is 100%

so subtract 22% from 100%

so u will get 78%

or dear u can try it in easy method also

total students=50

cant swim=11

who can swim=total students - who cant swim

=50-11=39

and we know that if we want to find percentage we will multiply it with 100

so students who can swim × 100 / total students

= 39×100/50 =78%

so childrens who can swim are 39 and percentage is 78%....

hope it helps uhh dear....u can do it in any way.....its ur choice ...
