The price of an article is raised by 30% and then two successive discounts of 10% each are allowed. Ultimately, the gain he received is 


  1. Increased by 5.3%

  2. Decreased by 5.3%

  3. Increased by 3%

  4. Increased by 10%

  5. Decreased by 5%


Solution

The correct option is A

Increased by 5.3%


Let the original price be Rs.100.Then, marked price =Rs.130.

Final price = 90% of 90% of Rs. 130 = Rs.(90100×90100×130) = Rs. 105.30

Increase in price = (105.30 - 100)% = 5.3%.
