Question

A trader gains 25% by selling an article at a discount 35% on its marked price.if the cost price of the article increases by 28%.What discount percent should he now give on the same marked price to get same profit percentage as before?

Answer 1

Let the marked price be Rs100

Then, Selling Price after 25 % discount =Rs75

Given, Profit % =

C.P.

S.P−C.P.

×100=25 %

=>

C.P.

75−C.P.

×100=25

=>75−C.P.=0.25C.P.

=>1.25C.P.=75

C.P.=Rs60

And if Selling Price =Rs100 (that is at marked price discount ),

then, Profit % =

C.P.

S.P−C.P.

×100=

60

100−60

×100=

60

40

×100=66 2/3%
