Answer 2

Answer:

CP=12,000

Step-by-step explanation:

sp= 13200

CP= ?

profit%=10%

profit=sp -cp

profit%= profit/cp×100%

10%=profit/13200-profit×100%

10%/100%=profit/13200-profit

Cross multipication:-

1×(13200-profit) =10×(profit )

13200-profit = 10 profit

10profit +profit = 13200

11profit =13200

profit =13200/11

profit=1,200

cp=sp-profit

= 13200-1200

= 12,000 (ans)

I hope it help you......
