Question
A person purchased 240 books at Rs.75 each and marked 40%
of these up by 40% and remaining by 60%. The books that are marked up by 40% are sold after allowing 30% discount and the books that are marked up by 60% are sold after allowing 20% discount, then what is the total amount of profit earned by the shopkeeper?Solution
Total cost price of the books = 240 * 75 = Rs.18000
Selling price of books that are marked 40% up and sold after allowing 30% discount = (70% of 140% of 75) * (40% of 240) = Rs.7056
Selling price of books that are marked 60% up and sold after allowing 20% discount = (80% of 160% of 75) * (60% of 240) = Rs.13824
Total SP = 7056 + 13824 = Rs.20880
Total amount of profit earned by the shopkeeper = 20880 - 18000 = Rs.2880
