Question

Decrease $Rs.5$ by $10\%$.

Answer 1

Step 1: Finding $10\%$of $Rs.5$.

As per given statement, $Rs.5$ is to be decreased by $10\%$.

$$\begin{gathered} \Rightarrow 10\%\times Rs.5 \\ \Rightarrow \frac{10}{100}\times 5=\frac{1\cancel{0}\times 5}{10\cancel{0}} \\ \Rightarrow \frac{5}{10}=0.5Rs \end{gathered}$$

Hence, $0.5Rs$ is to be reduced from $Rs.5$.

Step 2: Finding the new value after deceasing $10\%$of it.

$\Rightarrow Rs.5-Rs0.5=Rs4.50$

Hence, $Rs.4.50$ will be the value of $Rs.5$ after dectreasing by $10\%$
