Answer 2

Answer: ₹911.11

Step-by-step explanation:

Let cost price of article be x.

Given : Selling price of article = ₹820   (1)

Loss percent = 10%

Since, Loss % = $\dfrac{Loss}{C.P}\times100$

i.e. $10=\dfrac{Loss}{x}\times100$

i.e. $Loss=\dfrac{x}{10}=0.1x$

Also, Selling price = CP-Loss = x-0.1x=(1-0.1)x=0.9x

Substitute Value of S.P. from (1), we get

$0.9x=820\\\\\Rightarrow\ x=\dfrac{820}{0.9}=911.111111111\approx911.11$

Hence, its cost price = ₹911.11
