What an amount is increased by a percent, add the percent change to 100. 100 + 12 = 112. Use the proportion to get blank/ = is/of to get 112/100 = x/672

Answer 1

`753` students

Explanation:

Last year number of students
`=672`

Increase in next year
`=12\%`

`\left( x\%\ of\ an\ amount\ A =(x)/(100)* A \right)`

`12\%` of
`672=(12*672)/(100)=80.64`

So total increase in next year
`=80.64\approx81`

Hence total number of students next year = number of students last year
`+` increase

`=672+81\\=753`
