Question
The marked price of a book is 130 percent of its cost
price. If a 20% discount is offered while selling the book, find the profit percentage.Solution
ATQ,
Let the cost price of the book be Rs. '100x'
Marked price of the book = '100x' X 1.3 = Rs. '130x'
Selling price of the book = '130x' X 0.8 = Rs. '104x'
Profit earned on selling the book = '104x' - '100x' = Rs. '4x'
Required profit percentage = {(4x/100x) X 100} = 4%
