Question

The marked price of computer is Rs 22000. After allowing a 10% discount a dealer still makes a profit of 20% . Find the marked price of computer

Answer 1

The cost price of a product is the amount incurred in total to produce or manufacture the given item.

To find the cost price of the computer, assuming that this dealer is the manufacturer, the following is the procedure:

Profit = selling price - cost price

let the cost price be c

The selling price:  

= 10% discount

= discounted price = 100%(marked price) - discount (10%) = 90%

                              = 90%/100%  × 22000

                              = 0.9 × 22000

                              =  rs. 19800

This discounted price is the selling price.

Therefore profit  = 19800 - C

% profit = profit/ cost price ×100%

             = 19800-c/ c ×100% = 20%

             = 100(19800-c)/c = 20

 

             =   1980000 - 100c = 20c

             =  120c = 1980000

   

             =  c = 1980000/120

              c = Rs. 16500

Therefore the cost price of the computer is Rs. 16500

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Marked Price = Rs 22,000

Find the price after discount :

10% discount = 10% x 22,000 = 0.1 x 22000 = Rs 2200

Price after discount = 22000 - 2200 = Rs 19800

.............................................................................................

Find the cost price of the computer:

100 + 20 = 120%

120% = Rs 19,800

1% = 19800 ÷ 120 = Rs 165

100% = 165 x 100 = Rs 16,500

.............................................................................................

Answer: The cost price of the computer is Rs 16,500
