Q. What is the result when the number

20

is decreased by

20 \%

?

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the result of decreasing the number $20$ by $20$ %. This means we need to find $20$ % of $20$ and then subtract that value from $20$ .
Calculate $20$ % of $20$ : Calculate $20\%$ of $20$ . $\newline$ To find $20\%$ of a number, we can multiply the number by $0.20$ (since $20\%$ is the same as $\frac{20}{100}$ or $0.20$ ). $\newline$ $20\%$ of $20 = 20 \times 0.20$
Perform the calculation: Perform the calculation from Step $2$ . $\newline$ $20 \times 0.20 = 4$ $\newline$ So, $20\%$ of $20$ is $4$ .
Subtract the value found: Subtract the value found in Step $3$ from the original number. $\newline$ Now we subtract $4$ from $20$ to find the decreased value. $\newline$ $20 - 4 = 16$
