Question

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

Answer 1

Answer:

20%

Step-by-step explanation:

C.P. of 8 articles = S.P. of 10 articles = ₹ 80 (suppose)

∴ C.P. of 1 article = 80/8

= ₹10

And S.P. of 1 article = 80/10 = ₹8

∴ Loss = C.P. – S.P. = ₹10 - ₹8

= ₹2

Loss% = (Loss × 100)/C.P.

= (2 × 100)/10

= 20%
