We can see from the graph that for industrial sector, the usage is increased from 25 to 49 which is 96%. Hence, this is the maximum increase. For no other sector the usage became almost double.

1. Option D

Explanation:

Total exports of the three Companies X, Y and Z together, during various years are:

In 1993 = Rs. (30 + 80 + 60) crores = Rs. 170 crores.

In 1994 = Rs. (60 + 40 + 90) crores = Rs. 190 crores

In 1995 = Rs. (40 + 60 + 120) crores = Rs. 220 crores

In 1996 = Rs. (70 + 60 + 90) crores = Rs. 220 crores.

In 1997 = Rs. (100 + 80 + 60) crores = Rs. 240 crores.

In 1998 = Rs. (50 + 100 + 80) crores = Rs. 230 crores.

In 1999 = Rs. (120 + 140 + 100) crores = Rs. 360 crores.

Clearly, the total exports of the three Companies X, Y and Z together are same during
the years 1995 and 1996.

. Option: D

Explanation:

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

= 1/7 * (80 + 40 + 60 + 60 + 80 + 100 + 140) = 560/7 = 80

Average annual exports (in Rs. crore) of Company Z during the given period

1/7 * (60+90+120+60+80+100) = 600/7

:. Required percentage 80/(600/7)*100 % = 93.33%.

Option C

Explanation:

The difference between the exports from the Companies X and Y during the various
years are:

In 1993 = Rs. (80 - 30) crores = Rs. 50 crores.

In 1994 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1995 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1996 = Rs. (70 - 60) crores = Rs. 10 crores.

In 1997 = Rs. (100 - 80) crores = Rs. 20 crores.

In 1998 = Rs. (100 - 50) crores = Rs. 50 crores.

In 1999 = Rs. (140 - 120) crores = Rs. 20 crores.

Clearly, the difference is minimum in the year 1996.
