Question

The marked price of a watch is ₹16000. The shopkeeper gives two discounts to the customer, the first being $10\%$. If the customer pays ₹ 12240 for the watch, the second discount is :

• A. 18%
• B. 12.5%
• C. 15%
• D. 20%

Answer 1

The correct option is C 15%

After the first discount of $10\%$ on ₹16000,

Discount $=10\%$ of ₹ 16000

$=\frac{10}{100}\times 16000=₹1600$

Price of watch after 1st discount = ₹16000 - ₹1600 = ₹14400

As the customer pays ₹12240 after the second discount, the second discount amounts to:

₹14400 - ₹12240 = ₹2160

So the second discount percent is,

$\frac{2160}{14400}\times 100=15\%$.
