Question

A fan is listed at Rs. $1400$ and the discount offered is $10\%$. What additional discount must be given to bring the net selling price to Rs. $1200$?

• A. $16\frac{2}{3}\%$
• B. $5\%$
• C. $4\frac{16}{21}\%$
• D. $6\%$

Answer 1

The correct option is C $4\frac{16}{21}\%$

M.P. $=$ Rs. $1400$, discount rate $=10\%$
$\therefore$ Net price after $1^{st}$ discount $=90\%$ of Rs. $1400$
$=\frac{90}{100}\times 1400=$ Rs. $1260$
Final selling price $=$ Rs. $1200$
$\therefore$ Additional discount $=$ Rs. $1260-$ Rs. $1200=$ Rs. $60$
$\therefore$ Additional discount rate $=(\frac{60}{1260}\times 100)\%=4\frac{16}{21}\%$
