Question

the cost price of 20 articles is same as the selling price of x articles. if the profit is 25% then the value of x is

Answer 1

let the sp be x
cp of articles=20
profit=25%
sp=x×125/100=20
125x/100=20
125x=20×100
x=20×100/125
x=16

Answer 2

Answer:

16

Step-by-step explanation:

Let, 1 article price = Re.1

CP of 20 article = 20

SP of x article = 20

CP of x article = x

Profit = 20 - x

Profit(%) = {(20 - x)/x} * 100

So, Profit(%) = 25

or, (20 - x)/x = 25/100

or, (20 - x)/x = 1/4

or, 80 - 4x = x

or, 5x = 80

or, x = 16
