Answer 1

Answer:

$753$ students

Step-by-step explanation:

Last year number of students $=672$

Increase in next year $=12\%$

$\left( x\%\ of\ an\ amount\ A =\frac{x}{100}\times A \right)$

$12\%$ of $672=\frac{12\times672}{100}=80.64$

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

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

$=672+81\\=753$
