4.    Answer (3) 5000 + 300% of 5000 = 20,000

Hyderabad is req. answer.

5.    Answer  (3) 

6.    Answer: (4)

Required difference = (128000 - 107000) = 21000.

7.    Answer  (3) : 

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.    Answer: (1)

Average number of vehicles manufactured by Company X =1/6 *(119000 + 99000 + 141000 + 78000 + 120000 + 159000 =119333.

9.    Answer: (4)

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

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

10.  Answer: (2)

Required percentage = [(128000/ 78000) x 100]% » 164%

Answers:

1.    Answer: (B)

20% of the total funds to be arranged = Rs. (20% of 57600) crores

= Rs. 11520 crores » Rs. 11486 crores.

Rs. 11486 crores is the amount of funds to be arranged through External Assistance

2.    Answer: (C

Shortage of funds arranged through External Assistance  }= Rs. (11486 - 9695) crores

= Rs. 1791 crores.

Increase required in Market Borrowing = Rs. 1791 crores.

Percentage increase required = {[(1791 / 29952) ] x 100}% = = 5.98%  »6%.

3.    Answer: (C)
   Let Amount Permitted be x. 
    According to the question 

 x * 90% = 4910
then x = 5455.55 » 5455 crores 

4.    Answer: (C)

Central angle corresponding to Market Borrowing =[(29952/57600)]x 360º = 187.2º

5.    Answer: (B)

Required ratio = 4910/29952= 1/6.1 » 1/6

6.    Answer: (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 è 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 è y = ( 300 * 1.40 ) = 420

Imports in the year 1999 = Rs. 420 crores.

7.    Answer: (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.

8.    Answer (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.

9.    Answer: (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 è x = 272 / 0.85= 320

Exports in 1996 = Rs. 320 crores.

10.  Answer: (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.
