Question

A dealer allows a discount of Rs.10% and still gains by 10%. What should be the marked price if the cost price is Rs.900?

Answer 1

Let the marked price be x.

Given cost price = 900.

Given that gain = 10%.

SP = 900 + 10% of 900

     = 900 + 10/100 * 900

     = 900 + 90

     = 990.


Given that Discount = 10%.

SP = markedprice - 10% of 100

SP = x - 10/100 * 100

990 = x - 0.10x

990 = 0.9x

x = 1100.

The marked price = 1100.

Hope this help you..
