Marked price of a computer is Rs 14000. Selling price of computer is Rs 9702. If two successive discounts of 23% and y% are given, them what is the value of y?
Answer & explanation
Correct answer: option 2
Selling price = Marked price x discount
⇒ 9702 = 14000 x $\frac{77}{100}$ x $\frac{100-y}{100}$
⇒ $\frac{9702}{14000}$ x $\frac{100}{77}$ x 100 = 100 - y
⇒ 100 - y = 90
⇒ y = 10%
