Question

If $16\%$ of a number is $72$, find the number.

Answer 1

$16\%$ of a number is $72$. Find the number

Let the number $=x$

$\frac{16}{100}\times x=72$

$x=72\times \frac{100}{16}$

$x=450$

$\therefore$ The number is $450$

Now Let us check $1\%=\frac{450}{100}=4.5$

$16\%=4.5\times 16$

$16\%=72$
