Answer 1

Answer:

20%

Step-by-step explanation:

Let C.P. of 1 article =Rsx

Then, C.P. of 12 articles =Rs12x

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

So, S.P. of 15 articles= 12x

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

So, Loss % =

C.P.

C.P.−S.P.

×100=

15x

15x−12x

×100=
