Answer 2

Answer:

Percentage of student cam swim is = 70%

Percentage of student can not swim is = 30%

Step-by-step explanation:

As per the question,

Given data are

Total number of students in the school = 500

Number of student who can swim = 350

Therefore,

Percentage of student can swim is given by,

$\frac{Number \ of\ student \ who\ can\ swim}{Total \ number\ of \ student} \times 100$

=$\frac{350}{500}\times 100$

= 70 %

∴ Percentage of student cam swim is = 70%

Now,

Number of student who can not swim is given by,

Total number of students in the school - Number of student who can swim

= 500 - 350

= 150

∴ Number of student who can not swim = 150

Percentage of student can not swim is given by,

$\frac{Number \ of\ student \ who\ can\ not\ swim}{Total \ number\ of \ student} \times 100$

=$\frac{150}{500}\times 100$

= 30 %

∴ Percentage of student can not swim is = 30%
