Question

A shopkeeper buys a Printer set listed at Rs.10000 and get 10% and 20% successive discount. He spends 10% of his C.P. on transport. At what price (in rupees) should he sell the Printer set to earn a profit of 10%.

Answer 1

After 10% discount cp is Rs.9,000, cp after 20%discount on Rs.9,000 is Rs.7,200
now he spent 10% of cp in transport hence total cost is=7,200x(110/100)=Rs.7,920
in order to get 10% profit he should sell his product on the price tag of=7,920x(110/100)=Rs.8,712 is your answer.

Answer 2

First, let us calculate the cost after two discounts:
10000 - 10000 * 10/100 = Rs 9000
9000 - 9000 * 20/100 = Rs 7200
Second, We need to add the transportation cost
Transportation cost. 7200 * 10/100 = Rs 720
Then, the total cost is : 7200 + 720 = Rs 7920
In order to earn a profit of 10 %
He should sell the printer at the price of :
7920 + 7920 * 10/100 = Rs 8712

Answer 3

8712 he will sell the printer set
