Data Interpretation - Line Charts - Discussion
Study the following line graph and answer the questions.
Exports from Three Companies Over the Years (in Rs. crore)
Analysis of the graph: From the graph it is clear that
The amount of exports of Company X (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 30, 60, 40, 70, 100, 50 and 120 respectively.
The amount of exports of Company Y (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 80, 40, 60, 60, 80, 100 and 140 respectively.
The amount of exports of Company Z (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 60, 90,, 120, 90, 60, 80 and 100 respectively.
Average annual exports (in Rs. crore) of Company Y during the given period
| = | 1 | x (80 + 40 + 60 + 60 + 80 + 100 + 140) = | 560 | = 80. |
| 7 | 7 |
Average annual exports (in Rs. crore) of Company Z during the given period
| = | 1 | x (60 + 90 + 120 + 90 + 60 + 80 + 100) = |  |
600 |  |

 Required percentage = |

80 | x 100 | ![]](/_files/images/data-interpretation/common/15-sym-cbracket-h3.gif) |
%  93.33%. |

First, find percentage = 560*100/600 = 93.33.
total of Y=560
total of Z=600
so, percentage=560/600*100=93.33
I'm preparing for CAT-2010.
Can you please share tricks to solve Line Charts.
Thanks n regards,
