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. 16

C. 18

D. 25

**Answer : **B . 16

## Explanation:

Let Cost Price of each article be Re. 1

Cost Price of x articles = Rs. x.

Selling Price of x articles = Rs. 20.

Profit = Rs. (20 – x).

So {(20 - x) / x} x 100 = 25

x = 16
