Question

The marked price of a watch was Rs.7200. A man bought the same for Rs.5508 after getting two successive discounts, the first being 10%.
What was the second successive discount rate?


  1. 12%

  2. 18%

  3. 15%

  4. 19%

  5. 14%


Solution

The correct option is C

15%


Let the second discount rate be x%.

Then, (100x)% of 90% of 7200=5508

(100x)100×90100×7200=5508(100x)=(550809×72)=85x=15

Second successive discount rate = 15%
