Q. What is the result when the number

45

is increased by

20 \%

?

\newline

Answer:

Understand the problem: Understand the problem. $\newline$ We need to calculate the result of increasing the number $45$ by $20$ %. This means we need to find $20$ % of $45$ and then add it to $45$ .
Calculate $20$ % of $45$ : Calculate $20$ % of $45$ . $\newline$ To find $20$ % of a number, we can multiply the number by $0.20$ (since $20$ % is the same as $\frac{20}{100}$ or $0.20$ ). $\newline$ Calculation: $45 \times 0.20 = 9$
Add the $20\%$ to $45$ : Add the $20\%$ (which is $9$ ) to the original number ( $45$ ). $\newline$ Now we add the value from Step $2$ to the original number to find the increased amount. $\newline$ Calculation: $45 + 9 = 54$
