A discount of 10% is offered on the price of an article if the payment is made online. An additional discount of 5% is given to credit card holders. A person wishes to buy a watch priced at Rs 60,000 by paying online through credit card. How much does he need to pay (in Rs)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 51,300
Overall discount = x + y + xy/100
Overall discount = -10 -5 × (-10 × -5)/100
= -15 + 1/2 = -14.5 ( negative sign shows that it is a discount)
Overall discount offered = 14.5%
CP of the watch for a person = 60000 × 85.5% = 51300.
