Question

The marked price of a watch is Rs 800. A customer gets two successive discounts on the marked price, the first being 10%. What is the second discount if the customer pays Rs 612 for it?

• A. 14%
• B. 15%
• C. 17%
• D. 18%

Answer 1

Answer: (B)

15%

$M.P.=Rs800$, First discount $=$ 10%
$\therefore$ price after the first discount $=90$% of $Rs800=0.9\times Rs800=Rs720$
Final price after the second discount $=Rs612$
$\therefore$ Second discount $=Rs720-Rs612=Rs108$
$\Rightarrow$ Second discount rate $=\frac{108}{720}\times 100$% $=15$%.
