Question: "The cost price of a doll is Rs.250 and Marked price is Rs.300. What is the discount to be given to get the 20% profit?"
Solution: Let S.P=x
Profit%= (S.P - C.P)* 100 / C.P
20 = (x-250)* 100 / 250
20*250/100 = x-250
50 = x-250
50+250 = x
Hence S.P = Rs.300 & M.P = Rs.300
Hence discount = M.P-S.P = 300-300 = 0
Hence zero % discount is to be given to get 20% profit

Solution: Let S.P=x
Profit%= (S.P - C.P)* 100 / C.P
20 = (x-250)* 100 / 250
20*250/100 = x-250
50 = x-250
50+250 = x
Hence S.P = Rs.300 & M.P = Rs.300
Hence discount = M.P-S.P = 300-300 = 0
Hence zero % discount is to be given to get 20% profit

Proceeding with a further shortcut method to solve the problem mentally within 30 seconds...[email protected] wrote:Question: "The cost price of a doll is Rs.250 and Marked price is Rs.300. What is the discount to be given to get the 20% profit?"
20% => 1/5.
Given - to get the 20% profit <=> Profit = 1/5 th of Cost Price ( Coz profit is always calculated on the Cost Price )
Now , Profit is 50.
Selling price is 300 (250 + 50 = CP + P )
Marked Price is 300
So the shopkeeper doesn't allow any discount and sells the article at the marked price - Hence profit % is 0%...

[email protected] Whatever solution you posted is perfectly correct...
profit or loss % is always calculated on the cost price and not something else.
Also, whenever you post a query at BTG, please do it with options and as if the question is presented in the actual GMAT.
Hope this post was useful to you, thanx.
