Question

if the selling price of40article is esual to cost price of 50article find the loss or gain precent​

Answer 1

Answer:

Step-by-step explanation:

Let C.P of one article =1 Rs.

Then C.P of 40 article=40 Rs.

According to the question

S.P of 50 article =C.P of 40 article=40 Rs.

We assume that C.P of one article =1Rs.

then C.P of 50 article=50 Rs.

Loss=50-40=10 Rs.

Loss %=  

50

10

​  

×100=20%

Answer 2

Answer:let CP of 1 article = 10

CP OF 40 articles = 400

CP of 40 articles = SP of 50 articles

400. = SP of 50 articles

8. = SP of 1 article

As CP is greater than SP, loss occurs

loss = CP- SP

= 10-8 = 2

loss%= loss/CP * 100

= 2/10 *100

= 20%
