Question 1
For which of the following pairs of years the total exports from the three Companies together are equal?

A
1995 and 1998
B
1995 and 1998
C
1995 and 1998
D
1995 and 1996
Correct Answer: Option D

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.

Question 2
In which year was the difference between the exports from Companies X and Y the minimum?

A
1994
B
1995
C
1996
D
1997
Correct Answer: Option C

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.

Question 3

    = ₹[1x (30 + 80 + 60)]crores = ₹(170)crores.
33

Average exports of the three Companies X, Y and Z in 1998

    = ₹[1x (50 + 100 + 80)]crores = ₹(230)crores.
33

Difference
= ₹[(230)-(170)]crores
33
= ₹(60)crores
3
= ₹ 20 crores.
