A shopkeeper marks the price of an rs550 and gives the costumers a discount of 10% in this way he gains rs75 on article how much percent will the market price be more then the cost price?!

Below.

Step-by-step explanation:

When dealing with discounts, to find the amount that will be subtracted from the price, you will need to move the decimal two places (I think, don't quote me on that) to the right and then multiply the cost of the item with the discount. Seeing as the discount is 10% off, we have to multiply the cost of the item times the discount. (If the price of the rs550 is $100, we would times 100 by 0.10 to get $90.00 for the price of the item.)

Examples:

10% off = 0.10

60% off = 0.60

26% off = 0.26

etc.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
