8. What was the percentage increase in imports from 1997 to 1998 ?
SHOW ANSWER
Correct Ans:Data inadequate
Explanation:
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.
10. 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?
SHOW ANSWER
Correct Ans:Rs. 420 crores
Explanation:
From graph ,
( Imports in 1998 ) / ( Exports in 1998 ) = 1.25
( Imports in 1999 ) / ( Exports in 1999 ) = 1.40
Given ,Imports in 1998 = Rs. 250 crores
Exports in 1998 and 1999 = Rs. 500 crores
Let exports in 1998 = x crores Rs
exports in 1999 = ( 500 - x ) crores Rs
To find imports in 1999
=> ( Imports in 1999 ) / ( Exports in 1998 ) = 250 / x = 1.25
=> 250 / 1.25 = x
=> x = 200
( Imports in 1999 ) / ( Exports in 1999 ) = 1.40
=> Imports in 1999 / ( 500 - x ) = 1.40
=> Imports in 1999 / ( 500 - 200 ) = 1.40
=> Imports in 1999 = 1.40 * 300 = 420 crore Rs
11. In how many of the given years, were the exports from Company Z more than the average annual exports over the given years ?
SHOW ANSWER
Correct Ans:4
Explanation:
Average annual exports of Company Z during the given period
= (60 + 90 + 120 + 90 + 60 + 80 + 100) / 7
= 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.
15. For which of the following pairs of years the total exports from the three Companies together are equal ?
SHOW ANSWER
Correct Ans:1995 and 1996
Explanation:
Total exports of the three Companies X, Y and Z together, during various years are:
In 1993 = Rs. (30 + 80 + 60) crores = Rs. 170 crores.
In 1994 = Rs. (60 + 40 + 90) crores = Rs. 190 crores.
In 1995 = Rs. (40 + 60 + 120) crores = Rs. 220 crores.
In 1996 = Rs. (70 + 60 + 90) crores = Rs. 220 crores.
In 1997 = Rs. (100 + 80 + 60) crores = Rs. 240 crores.
In 1998 = Rs. (50 + 100 + 80) crores = Rs. 230 crores.
In 1999 = Rs. (120 + 140 + 100) crores = Rs. 360 crores.
Clearly, the total exports of the three Companies X, Y and Z together are same during the years 1995 and 1996.
20. 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 ?
SHOW ANSWER
Correct Ans:Rs. 420 crores
Explanation:
Solutions:
From graph , ( Imports in 1998 ) / ( Exports in 1998 ) = 1.25
( Imports in 1999 ) / ( Exports in 1999 ) = 1.40
Given ,Imports in 1998 = Rs. 250 crores
Exports in 1998 and 1999 = Rs. 500 crores
Let exports in 1998 = x crores Rs
exports in 1999 = ( 500 - x ) crores Rs
To find imports in 1999
=> ( Imports in 1999 ) / ( Exports in 1998 ) = 250 / x = 1.25
=> 250 / 1.25 = x
=> x = 200
( Imports in 1999 ) / ( Exports in 1999 ) = 1.40
=> Imports in 1999 / ( 500 - x ) = 1.40
=> Imports in 1999 / ( 500 - 200 ) = 1.40
=> Imports in 1999 = 1.40 * 300
= 420 crore Rs
