Question

The cost price of 20 articles is the same as the selling price of x articles.The value of x is (given profit =20%).

Answer 1

Let C.P. of each article be Rs. 1

=> C.P. of x articles=Rs.x.

S.P. of x articles=Rs. 20.

Profit=Rs.(20 - x).

$\frac{20-x}{x}\times 100$=25.

2000 - 100x=25x.

125x=2000.

$\Rightarrow$ x=16.
