A school has 380 students of whom 70% can swim. If 40% of the boys connot swim and 200 girls can swim, how many girls are there in the school

263

Step-by-step explanation:

380=total

70%=swimmers

70%*380=266swimmers

30%=non swimmers

i. e. 100%-70%

380-266=114 non swimmers

40%of 114are boys

=46boys

60%are girls

i. e. 100%-40%

114-46=68

68+200=268girls

There are 200 girls in that school
