A Person Bought An Article And Sold It At A Loss Of 10%. If He Had Bought It For 20% Less And Sold It For Rs. 55 More. He Would Have Had A Profit Of 40%. The C.p. Of The Article Is ?

Answer»

<P>LET C.P. = Rs. P

Then S.P. = Rs. (90/100) X P = Rs. (9 x P)/10

NEW C.P. = Rs. (80/100) x P = Rs. (4 x P)/5

Now, Gain = 40%

∴ New S.P. Rs. (140/100 x 4P/5) = Rs. 28P/25

∵ 28P/25 - 9P/10 = Rs. 250

Let C.P. = Rs. P

Then S.P. = Rs. (90/100) x P = Rs. (9 x P)/10

New C.P. = Rs. (80/100) x P = Rs. (4 x P)/5

Now, Gain = 40%

∴ New S.P. Rs. (140/100 x 4P/5) = Rs. 28P/25

∵ 28P/25 - 9P/10 = Rs. 250
