Solution

Total number of students = 500

Number of students who can swim = 370

Percentage of students who can swim = `370/500 xx 100%` = 74%

Number of students who cannot swim = 500 – 370 = 130

Percentage of students who cannot swim = `130/500 xx 100%` = 26%

i.e. 74% can swim and 26% cannot swim
