Question

A man bought 20 articles at rs 25 and sold 30 articles at rs 45 what is the loss or gain%

Answer 1

Answer:

Step-by-step explanation:

CP of 20 articles = 25 rs

SP of 30 articles = 45 rs

CP of 1 article = 25/20=5/4

SP of 1 article = 45/30=3/2

Profit=SP-CP

        =3/2-5/4

        =1/4

Gain%=Gain/CP*100

          =1/4/5/4*100

Gain% =20%
