C 15 Correct Answer Incorrect Answer
D 16 Correct Answer Incorrect Answer
E 17 Correct Answer Incorrect Answer

Solution

Let the Cost Price of each article = Rs. x
CP of x articles = Rs. x
SP of x articles = Rs. 20
Profit = Rs. (20 - x)
Therefore,
=> [(20-x)/x]× 100 = 25
=> 2000 - 100x = 25x
=> 125x = 2000
=> x = 16
