Question

The ratio of cp and sp of an article is 20:21 what is the gain percent

Answer 1

answer-

ratio of cp to sp is 20:21

let the ratio be in terms of x

so cp = 20x

sp = 21x

profit or gain = sp-cp

= 21x-20x

profit=x

profit% = profit*100/cp

profit% = x*100/20x

we will cancel x with x

so profit % = 100/20

profit % = 5%

hope it helps

have a nice day
