Question

After allowing a discount of 10% on the marked price, a trader still makes a profit of 17%. By what per cent is the marked price above cost price?​

Answer 1

Step-by-step explanation:

Let the cost price be 100 Rupees.There is gain of 17% so, Selling price will be 117 Rupees.Sp=117

Let marked price be x

Then 90%of X=117

(90/100)x=117

x=117*100/90

=130

Above cost price=130-100=30

So, marked price is 30 rupees more than CP.

So, shopkeeper must mark his good's price 30% more than cost price.

Answer 2

Step-by-step explanation:

Let The MP be 100

so,

100 + 17%× 100

117 ....

So,

90% × X = 117

X = 117×100/90

X = 130..

so,

30/100 × 100

30% is Ur answer....
