Question

If selling an article for 2820 causes 10% loss on the selling price, then find its cost price,​

Answer 1

Step-by-step explanation:

selling price of article S.P = 2820

percentage loss = 10%

let cost price be x

then loss = C.P - S.P = x - 2820

now loss % = loss/C.P × 100

$10 = \frac{x - 2820}{x} \times 100$

$1 = \frac{x - 2820}{x} \times 10$

x = 10x - 28200

9x - 28200

= 2811

C.P = 2811
