The graph below represents number of bikes sold over a period of seven months. Observe the graph and answer the question that follows:

In which of the following months, was the sales nearest to the average sales for the period January to July?

​

Correct option is C

Solution:      

Average sale January to July =$$\frac{200+ 300+100+200+400+500+600}{7}$$

= $$\frac{2300}{7}$$   = 328.57

Then the average sale January to July is nearest sale of February(300).
