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 of the company in 1996 was Rs. 272 crores, the exports from the company in 1996 was ?

A.

Rs. 370 crores

B.

Rs. 320 crores

C.

Rs. 280 crores

D.

Rs. 275 crores

Correct answer is B

Ratio of imports to exports in the year 1996 = 0.85

Let the exports in 1996 = Rs. x crores.

Then, 272/x = 0.85  =>  x = 272/0.85 = 320

Therefore Exports in 1996 = Rs. 320 crores.

Hence, the data is inadequate to answer this question.

A.

1995

B.

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.
