# Data Interpretation - Bar Charts - Discussion

The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years.

Production of Paper (in lakh tonnes) by Three Companies X, Y and Z over the Years. 4.

In which year was the percentage of production of Company Z to the production of Company Y the maximum?

 [A]. 1996 [B]. 1997 [C]. 1998 [D]. 1999

Explanation:

The percentages of production of Company Z to the production of Company Z for various years are:

 For 1996 = 35 x 100 % = 140%. 25

 For 1997 = 40 x 100 % = 114.29%. 35

 For 1998 = 45 x 100 % = 128.57%. 35

 For 1999 = 35 x 100 % = 87.5%. 40

 For 2000 = 35 x 100 % = 70%. 50

Clearly, this percentage is highest for 1996.
