Question

The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then what is the value of x ?

Answer 1

SP={(100+gain)/100}×CP
SP={(100+25)/100}×20
SP=(125/100)×20
SP=1.25×20
SP=25

Answer 2

Answer:

16

Step-by-step explanation:

Let,

1 article price is Re.1

CP of 20 articles = 20

SP of x articles = 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
