Question

Sanjay purchased a chair marked at $Rs.800$ at $2$ successive discount of $10\%$ and $15\%$ respectively. He spent $Rs.25$ on transportation and sold the chair for $Rs.800$. How much is his gain percentage ?

• A. $14\%$
• B. $30\%$
• C. $25\%$
• D. $40\%$

Answer 1

The correct option is C $25\%$

M.P. of chair = Rs. $800$

After discount let the price of chair be $x$

$x=800\times \left(\frac{90}{100}\right)\times \left(\frac{85}{100}\right)=Rs.612800\times 90100\times 85100=Rs.612$

After transportation total price incurred $=612+25=Rs.637$

S.P of chair $=Rs.800$

$Profit=800-637=Rs.163$

$Profit\%=\left(\frac{163}{637}\right)\times 100=25.5886\%\cong 25\%$
