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.
Study the following line graph and answer the questions.
Exports from Three Companies Over the Years (in Rs. crore)
Rs. 15.33 crores
Rs. 18.67 crores
Rs. 20 crores
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?
1994
1995
1996
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.
