Question

by selling 33 metre of cloth A shopkeeper loses an amount equal to the selling price of 3 metre of cloth find his loss percent

Answer 1

Let x be the price of 1 m cloth.
then,
Price of 33m cloth =  33x
Price of 3m cloth = 3x = loss
Selling price of cloth = CP - Loss
                                    = 33x - 3m = 30x
loss% = 3x/33x * 100
           = 3/33 * 100
           = 100/11
           = 9.09% 

If there is any problem, pls. correct it. I hope you are satisfied with your answer ;) !!!
