Question

By selling an article for rs.100 a merchant gains rs.20 find gain percent.​

Answer 1

Let CP = rs.x

Then, gain = rs.(100-x)

But, A/q Gain = rs.20

So, 20 = 100-x

Or, x = 100-20 = 80

Hence, gain% = {(20/80)×100}% = 25%

Answer 2

Answer:

25%

Step-by-step explanation:

SP=Rs.100

Profit=Rs.20

CP=SP-Profit

CP=100-20

CP=Rs.80

Profit%=profit/CP×100

20/80×100

25%
