Question

A dealer allows a discount of rupees 10 percent and still gains by 10 percent what should be the marked price if the cost price is 900rupees

Answer 1

the cost Price is 900 and the Overall gain is 10%, So the Selling Price = 900x110/100= 990. Now the marked price has to be higher then the selling price coz the dealer offers a discount of 10%. So the Marked price= 990x100/90= 1100 rs.( Remember that loss and discount percentage are alwasys subtracted from 100).

Answer 2

the cost Price is 900 and the Overall gain is 10%,
So the Selling Price = 900x110/100= 990.
Now the marked price has to be higher then the selling price coz the dealer offers a discount of 10%.
So the Marked price= 990x100/90= 1100 rs.( Remember that loss and discount percentage are always subtracted from 100).
