Marked price of a computer is Rs 10000. Selling price of computer is Rs 7650. If two successive discounts of 15% and x% are given, then what is the value of x?
Answer & explanation
Correct answer: option 3
Selling price = Marked price x discount%
7650 = 10000 x $\frac{85}{100}$ x $\frac{100-x}{100}$
7650 = (85)(100 - x)
100 - x = 90
x = 10%
