|
Answer is: AThe 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.
34. | | What was the difference between the average exports of the three Companies in 1993 and the average exports in 1998? | | (a)Rs. 15.33 crores | | (b)Rs. 18 crores | | (c)Rs. 20 crores | | (d)Rs. 25.33 crores |
|
Answer is: CAverage exports of the three Companies X, Y and Z in 1993
= Rs. [1/3(30 + 80 + 30)] crores = Rs. (170/3) Crores.
Average exports of the three Companies X, Y and Z in 1998
= Rs. [1/3(50 + 100 + 80)] Crores = Rs. (230/3) Crores.
Difference = Rs.[(230/3) - (170/3)] Crores
Difference = Rs. (60/3) = Rs. 20 crores.

38. | | What is the ratio between the number of students studying at post graduate and graduate levels respectively from institutes S? | | (a)14 : 19 | | (b)13 : 21 | | (c)17 : 14 | | (d)19 : 14 |
|
