Selling price of
x articles. If the profit is 25%
then the value of x is:​

Answer 1

Answer:

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x

S.P. of x articles = Rs. 20

Profit = Rs. (20 - x)

∴

20−x

x

×100=25 ⇒2000−100x=25x 125x=2000 ⇒x=16

Answer 2

Answer:

x = 16

Step-by-step explanation:

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x

S.P. of x articles = Rs. 20

Profit = Rs. (20 - x)

∴ {(20 - x)/x} × 100 = 25

⇒ 2000 − 100x = 25

=> 125x = 2000

⇒ x = 16
