Given , Selling price = 9000, Loss = 10%.

We know that Cost price = [100/(100 - Loss%)] * SP

⇒ [100/(100 - 10)] * 9000

⇒ [100/90] * 9000

⇒ 10000.


Given Selling price = 12000.

Here, Selling price > Cost price. So, gain has occured.

We know that Gain = Selling price - Cost price

                                = 12000 - 10000

                                = 2000.



We know that Gain% = (Gain/CP) * 100

                                   = (2000/10000) * 100

                                   = 20.



Therefore, %Gain = 20%.



Hope this helps!

cp = (100/100-loss%) *sp
cp = (100/90)*9000
cp = 10000
if sp is 12000 then
profit = 12000-10000=2000
profit % = (profit /cp)*100
profit % = (2000/10000)*100= 20%
