Answers 

1. 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.

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, 40 = y/300 

y = (300 * 1.40) = 420

Imports in the year 1999 = Rs. 420 crores.

2. C

The imports are minimum proportionate to the exports implies that the ratio of the value of imports to exports has the minimum value.

Now, this ratio has a minimum value 0.35 in 1997, i.e., the imports are minimum proportionate to the exports in 1997.

3. D

 The graph gives only the ratio of imports to exports for different years. To find the percentage increase in imports from-

 1997 to 1998, we require more details such as the value of imports or exports during these years.

Hence, the data is inadequate to answer this question.

4. 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                   

Exports in 1996 = Rs. 320 crores.

5.  D

The exports are more than the imports imply that the ratio of value of imports to exports is less than 1.

Now, this ratio is less than 1 in years 1995, 1996, 1997 and 2000.

Thus, there are four such years.

6.  D

 Required difference = (128000 - 107000) = 21000.

7.  C

 From the line-graph it is clear that the productions of Company X in the   years 1997, 1998, 1999, 2000, 2001 and 2002 are-

 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 -

and 148000 respectively.Total production of Company X from 1997 to 2002

= 119000 + 99000 + 141000 + 78000 + 120000 + 159000

= 716000.

and total production of Company Y from 1997 to 2002

= 139000 + 120000 + 100000 + 128000 + 107000 + 148000

= 742000.

Difference = (742000 - 716000) = 26000.

8. A

  Average number of vehicles manufactured by Company X

= 119333.

9. D

The difference between the productions of Companies X and Y in various years are:

For 1997 (139000 - 119000)  = 20000.

For 1998 (120000 - 99000)  = 21000.

For 1999 (141000 - 100000)  = 41000.

For 2000 (128000 - 78000) = 50000.

For 2001 (120000 - 107000) = 13000.

For 2002 (159000 - 148000) = 11000.

Clearly, maximum difference was in 2000.
