Study the following line graph and answer the questions based on it.
Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
1997
1998
1999
2000
Correct answer is 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

Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
119333
113666
112778
111223
Correct answer is A
Average number of vehicles manufactured by Company X
= 1/6 x (119000 + 99000 + 141000 + 78000 + 120000 + 159000)
= 119333.

What is the difference between the total productions of the two Companies in the given years ?
19000
22000
26000
28000
Correct answer is 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.

What is the difference between the number of vehicles manufactured by Company Y in 2000 and 2001 ?
50000

21000
Correct answer is D
Required difference = (128000 - 107000) = 21000.
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.
In how many of the given years were the exports more than the imports ?
1
2
3
4
Correct answer is 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.
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 ?
Rs. 370 crores
Rs. 320 crores
Rs. 280 crores
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.

Ratio of Value of Imports to Exports by a Company Over the Years.
What was the percentage increase in imports from 1997 to 1998 ?
72
56
28
Data inadequate
Correct answer is 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.
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.
The imports were minimum proportionate to the exports of the company in the year ?
1995
1996
1997
2000
Correct answer is 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.
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.
Rs. 250 crores
Rs. 300 crores
Rs. 357 crores
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)
2
3
4
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.
