Then, C.P. of 12 articles =Rs12x

Given, S.P of 15 articles = C.P. of 12 articles

Since, S.P.<C.P., for 15 articles there is a Loss

So, Loss % =

C.P.

C.P.−S.P.

Answer 2

Answer:

Let S.P. of 1 article = Rs. 1.

Then, C.P. of 12 articles = S.P.of 10 articles = Rs. 10

S.P. of 12 articles = Rs. 12

∴ Profit = Rs. 12 − Rs. 10= Rs. 2

⇒Profit %= ( 102 ×100) %=20%
