The table given below shows the cost price and selling of four different articles.

What is the difference between the average selling price and average cost price of all the articles?

110

Average selling price = \(\frac{ 750 + 450 + 650 +  650 }{4}\)

= \(\frac{ 2500 }{4}\) = 625

Average Cost price = \(\frac{650 + 370 + 450 +  590 }{4}\)

= \(\frac{ 2060 }{4}\) = 515

Difference = 625 - 515 = 110
