The line chart given below shows the cost price and selling price of four articles.
What is the ratio of average selling price of M and N to the average cost price of P and Q ?
Answer & explanation
Correct answer: option 3
Average selling price of M & N = \(\frac{400 + 650 }{2}\)
= 525
Average cost price of P & Q = \(\frac{600 + 900 }{2}\)
= 750
Required ratio = 525 : 750
= 7 : 10
