Question

how much above the cost price should a dealer mark his goods so that after allowing a discount of 10% on the Marked price he gains 8%​

Answer 1

Let the marked price be x.

Let the cost price be 100.

Then the selling price = 100 + 8

                                    = 108.

Given that the dealer allows the discount of 10% on the marked price.

90% of x = 108

90/100 * x = 108

90 * x = 108 * 100

90 * x = 10800

x = 10800/90

x = 120.

Therefore the Marked price is 20% above the cost price.

Answer 2

Answer:

20%

Step-by-step explanation:

let marked price (mp) be = x

let cost price (cp) be = 100

so,

Selling price (sp) = 100% + profit%

= 100% + 8%

= 108%

sp = x - 10% of x

108. = x - (10x / 100)

108 = 100x - 10x / 100

108 * 100 = 90x

10800 / 90 = x

120 = x

so, x = 120

last step :-

(120 - 100 / 100) * 100

= 120 - 100

= 20%
