Question
The marked price of a watch was Rs. 720.A man brought the same for Rs.550.80 after getting two successive discounts the first being 10% .What was the second discount rate?
Answer: Option C
- Let the second discount rate be x% Then,
(100 – x)% of 90% of 720 = 550.80
=> (100 – x)/100 x 90/100 x 720 = 550.80
= (100-x) = [55080/(9 x 72) = 85
=> x= 15
second discount rate =15%
