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
