87.12%
89.64%
91.21%
93.33%
Answer: Option
Explanation:

Analysis of the graph: From the graph it is clear that

  1. 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.

  2. 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.

  3. 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 ) .
7 7

Therefore Required percentage = [ 80 x 100 ] % ~= 93.33%.
( 600 )

No need to calculate average! because each company contain 7 years exports.
total of Y=560
total of Z=600
so, percentage=560/600*100=93.33

No need to find average directly,

First, find percentage = 560*100/600 = 93.33.
