Question

the cost price of 25 articles is equal to selling price of 20 articles

Answer 1

Answer:

gain =sp-cp

gain = 20+(-25)

gain = 5

Answer 2

Step-by-step explanation:

cost price of 25 articles = selling price of 20 articles.

let the CP of one article be one rupees.

So, CP of 25 articles = 25 rupees

since SP of 20 article = CP of 25 article.

therefore,SP of one article = 25 /20

=5/4

i.e. SP is greater than CP(5/4>1)

therefore,it's a gain.

Gain=SP-CP

= 5/4 -1

=1/4

GAIN%=1/4/1*100

=25%
