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
