A.

1995

B.

1996

C.

1997

D.

2000

The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.

Ratio of Value of Imports to Exports by a Company Over the Years.

If the imports in 1998 was Rs. 250 crores and the total exports in the years 1998 and 1999 together was Rs. 500 crores, then the imports in 1999 was ?

A.

Rs. 250 crores

B.

Rs. 300 crores

C.

Rs. 357 crores

D.

Rs. 420 crores

Correct answer is D

The ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.

Let the exports in the year 1998 = Rs. x crores.

Then, the exports in the year 1999 = Rs. (500 - x) crores.

Therefore 1.25 = 250/x  =>  x = 250/1.25 = 200 [Using ratio for 1998]

Thus, the exports in the year 1999 = Rs. (500 - 200) crores = Rs. 300 crores.

Let the imports in the year 1999 = Rs. y crores.

Then, 1.40 = y/300   =>  y = (300 x 1.40) = 420

Therefore Imports in the year 1999 = Rs. 420 crores.

Study the following line graph and answer the questions.

Exports from Three Companies Over the Years (in Rs. crore)

In how many of the given years, were the exports from Company Z more than the average annual exports over the given years?

A.

2

B.

3

C.

4

D.

5

Correct answer is C

Average annual exports of Company Z during the given period

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

= Rs. ( 600/7 ) crores

= Rs. 85.71 crores.

From the analysis of graph the exports of Company Z are more than the average annual exports of Company Z (i.e., Rs. 85.71 crores) during the years 1994, 1995, 1996 and 1999, i.e., during 4 of the given years.

Study the following line graph and answer the questions.

Exports from Three Companies Over the Years (in Rs. crore)

What was the difference between the average exports of the three Companies in 1993 and the average exports in 1998?

A.

Rs. 15.33 crores

B.

Rs. 18.67 crores

C.

Rs. 20 crores

D.

Rs. 22.17 crores

Correct answer is C

Average exports of the three Companies X, Y and Z in 1993

= Rs. [ 1/3 x (30 + 80 + 60) ] crores = Rs. ( 170/3 ) crores

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

= Rs. [ 1/3 x (50 + 100 + 80) ] crores = Rs. ( 230/3 ) crores

Difference = Rs. [ ( 230/3 ) - ( 170/3 ) ] crores 

= Rs. ( 60/3 ) crores

= Rs. 20 crores

Study the following line graph and answer the questions.

Exports from Three Companies Over the Years (in Rs. crore)

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 is 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.
