Question 72
The marked price of an article is ₹740. After two successive discounts of 15% and x %,it is sold for ₹566.10. What is the value of x ?
Solution
Marked price = 740
According to question,
Selling price = 740 $$\times \frac{100 - 15}{100} \times \frac{100 - x}{100}$$
740 $$\times \frac{100 - 15}{100} \times \frac{100 - x}{100} = 566.10$$
740 $$\times \frac{85}{100} \times \frac{100 - x}{100} = 566.10$$
740$$\times \frac{17}{20} \times (100 - x) = 56610$$
(100 - x) = 56610/629
100 - x = 90
x = 10
