Question

find the loss or gain percent if the CP of 8 articles is equal to SP of 10 articles​

Answer 1

Answer:

let the cp of 1 article be 100

cp of 8 article is 800

800 = sp of 10 article

sp of 1 artcle = 80

loss = 100 - 80

loss = 20

loss percent = 20 / 80 × 100

loss percent = 25 percent

Answer 2

Answer:

Step-by-step explanation:

Always assume CP for this type of question:

Let price of 1 article=1 Rs

Cp of 8 articles =8*1 Rs=Sp of 10 articles

Now Cp of 10 articles = 10*1RS

loss=SP-Cp=8-10=-2

%Loss=(loss/Cp)*100=(-2/10)*100=-20
