Question

Please answer with explanation. Tomorrow is my exam.​

Answer 1

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−xx×100=25⇒2000−100x=25x125x=2000⇒x=16

OR

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

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x. S.P. of x articles = Rs. 20.

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).

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−xx*100=25)

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−xx*100=25) => 2000 - 100x = 25x

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−xx*100=25) => 2000 - 100x = 25x => 125x=2000

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−xx*100=25) => 2000 - 100x = 25x => 125x=2000 => x=16

BOTH ANSWERS ARE SAME
