Question

The selling price of a pen is $Rs.13.20$ if it is sold at $12\%$ discount.

Find the new selling price of the pen, if it is sold at $5\%$ discount.

• A. $Rs.12.11$
• B. $Rs.14.25$
• C. $Rs.15.33$
• D. $Rs.16.26$

Answer 1

Answer: (B)

$Rs.14.25$

Let the marked price of the pen be $x.$

For the case when discount is $12\%,$ $SP$ is $Rs.13.20$. Then,

$\begin{array}{cc}13.20& =x\left(1-\frac{12}{100}\right)\\ 13.20& =x\times \frac{88}{100}\\ x& =\frac{13.20\times 100}{88}\\ & =Rs.15\end{array}$

For the case when the discount is $5\%,$ $SP$ will be,

$\begin{array}{cc}SP& =15\left(1-\frac{5}{100}\right)\\ & =15\times \frac{95}{100}\\ & =Rs.14.25\end{array}$

Hence, option $B$ is correct.
