Question

if the selling price of 20 articles is equal to the cost of 15 articles then what is the loss percent​

Answer 1

Let the c.p. of 1 article be Rs.1

Then,C.P.of 23 articles=Rs.23

S.P.of 20 articles=Rs.23

S.P. of 1 article=Rs.23/20

Let the number of articles be x.

Then total C.P.=1*x=Rs.x

And total S.P.=23/20*x=Rs.23x/20

Since S.P.>C.P. there is a profit

Profit=Rs.(23x/20-x)=Rs.3x/20

Profit percentage=(3x/20)/x*100%=15%

Answer:The gain percentage is 15%
