Answer 2

Answer:

25% is the profit percent on 8 articles.

Step-by-step explanation:

(we have taken 100 to assume the cost,we can take any value.

for convinience we have taken 100rupees ok.)

so let the cp of 10 articles=rs.100

then the sp of 8 articles will be also =rs.100

cp of 1 article by applying the unitary method=>

if cp of 10 articles is 100 then cp of 1 article is 100/10 which is rs.10

so cp of 1 article =10 then

cp of 8 article will be =10*8=rs.80

so the cp of 8 article isrs,80

we have cp of 8 articles now and sp of 8 articles ,

we can now say

cp =80

sp =100

profit =rs.20

profit percent=profit*100/cp

so putting the values we get,

20*100/80=2000/80=25%

so thus the profit percent is 25%.
