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
Correct Option:
B
Explanation
A profit of 25% means SP = 1.25 CP. If the cost price of 20 articles equals the selling price of x articles, 20 CP = x(1.25 CP). Cancelling CP gives 20 = 1.25x, so x = 16.
