Answer 1

Answer:

Number of articles sold = 20

Cost of 20 articles = ₹30

So, Cost of 1 article = 30/20

and, Cost of 4 articles = 30/20 X 4

                            = ₹6 [which is equal to the profit made]

So, profit made by trader = ₹6

Profit percentage = 6/30 X 100

                             = 20%
