Question

12. Find the loss or gain as percent, if the C.P. of 8 articles, all of the same kind, is equal
to S.P. of 10 articles.​

Answer 1

Answer:

20%

Step-by-step explanation:

Let the CP of 1 article = ₹ 1

Then,

the CP of 8 articles = ₹8              (8 * 1 = 8)

the CP of 10 articles =  ₹10           (10 * 1 = 10)

Given,

SP of 10 articles = CP of 8 articles

SP of 10 articles =  ₹8

Loss = CP of 10 articles - SP of 10 articles

Loss = ₹10 -  ₹8

= ₹2

Loss % = (loss/cp) * 100

Loss % =( 2/10 * 100)

= 20%
