Question

A man sell an article at a profit of 5% . . if he had bought it at 5% less less he would have gained 10% . find cp

Answer 1

Step-by-step explanation:

Let original Cost price of 1 article CP1=Rsx

Then Selling price of the article =SP1=100100+5x=100105x

 

=> If he had bought it for 5 % less, then CP2=100100−5x=10095x

And sold it for Rs2 less, then SP2=Rs100105x−2

Given  Profit % =C.P.2S.P.2−C.P.2×100=10

=>10095x100105x−2−10095x×100=10

=>95x10x−200×100=10

=>10x−200=9.5x

=>0.5x=200

x=400

Thus, C.P. 1 =Rs400
