Question

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

• A. 15
• B. 25
• C. 18
• D. 16

Answer 1

The correct option is D

16

Let C.P. of each article be Re. 1, then C.P of x articles = Rs. x.
S.P. of x articles = Rs.20.
Profit = Rs. (20 - x).
$\therefore (\frac{20-x}{x}\times 100=25)$
$\Rightarrow$ 2000 - 100x = 25x
125x = 2000
$\Rightarrow$ x = 16.
