The following chart shows the sales (in thousands) of pens, pencils and books in month1, month2 and month3. Answer the question based on the chart.

What is the average number of pens sold in the 3 months ?

5033

Total sale of pens in all 3 months  = 5.6 + 4.9 + 4.6 = 15.1

Average sale of all 3 months = \(\frac{15.1 }{3}\)

= 5.033 ( in thousands )

= 5033
