Question

the cost price of 20 articles is same as the selling price of 16 articles. find the fain percent.​

Answer 1

Answer:

C.P. of 20 articles = S.P. of 16 articles.

Let C.P. of 1 article = Re. 1

C.P. of 20 articles = Rs.20

and C.P. of 16 articles = Rs.16

S.P. of 16 articles = Rs.20

[S.P. of 16 articles = C.P. of 20 articles]

Gain = Rs.20 – Rs.16 = Rs.4

Gain% = 4/16 x 100

= 4x100/16

= 25%
