Two successive discounts each of x % on the marked price of an article are equal a single discount of ₹350. If the marked price of the article is ₹800, then the value of x is:

25%

Marked price of the article = 800

Two successive discounts of x is given by = x + x - \(\frac{x^2}{100}\)

According to the question=

800 × ( x + x - \(\frac{x^2}{100}\)%) = 350

2x - \(\frac{x^2}{100}\) = \(\frac{175}{4}\)

x = 25%
