pls say this answer​

Answer 1

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% =

$\: \frac{4}{16} \times 100$

= 25%
