Q. The price of an article is raised by 30% and then two successive discounts of 10% each are allowed. Ultimately the price of the article is :
Answer: increased by 5.3%
Notes: Let the original price be 100 Rs. ∴ Increased Price = 130 Rs. Equivalent discount = $latex = \left ( 10+10-\frac{10\times 10}{100} \right ) = 19\%&s=1$ ∴ Ultimate price of the article = 81% of 130 = 105.3 so the price of the article is increased by 5.3%. Hence option [D] is correct answer.
