Solution

To calculate the percentage of a number, we need to use a different formula such as:
$P %$ of Number $= x$
where $x$ is the required percentage.
If we remove the $%$ sign, then we need to express the above formulas as;
$\frac{P}{100} \times N u m b e r = X$
Percentage’ is obtained by multiplying $40 %$ by $50$ i.e,
$40 % \times 50 \frac{40}{100} \times 50 \frac{(40 \times 50)}{100} \frac{2000}{100} 20$
Hence, $40 %$ by $50$ is $20$ .
