Answers:-




1.(D)
DIFFERENCE = Rs. [(10% of 4.75) – (8% of 4.75)]
= Rs. (2% of 4.75) lakhs
= Rs. 0.095 lakhs
= Rs. 9500.


2.(D)
Let the amounts invested in 2002 in Companies P and Q be Rs. 8x and Rs. 9xrespectively.
Then, interest received after one year from Company P= Rs. (6% of 8x)
=Rs.48x/100
and interest received after one year from Company Q= Rs. (4% of 9x)
=Rs.36x/100
Required ratio =(48x/100)/(36x/100)=4/3


3.(D)
Let Rs. x lakhs be invested in Company P in 2000, the amount invested in Company Q in
2000 = Rs. (30 – x) lakhs.
Total interest received from the two Companies after 1 year
= Rs. [(7.5% of x) + {9% of (30 – x)}] lakhs
= Rs. {2.7 -(1.5x/100)}lakhs.
2.7 -1.5x/100= 2.43  
 x = 18.


4.(C)
Amount received from Company P after one year (i.e., in 199) on investing Rs. 12 lakhs in it
= Rs. [12 + (8% of 12)] lakhs
= Rs. 12.96 lakhs.
Appreciation received on investment during the period of two years
= Rs. (14.256 – 12) lakhs
= Rs. 2.256 lakhs = Rs. 2, 25,600.


5.(B)
Amount received from Company Q after one year on investment of Rs. 5 lakhs in the year1996
= Rs. [5 + (6.5% of 5)] lakhs
= Rs. 5.325 lakhs.
Amount received from Company P after one year on investment of Rs. 5.325 lakhs in theyear 1997
= Rs. [5.325 + (9% of 5.325)] lakhs
= Rs. 5.80425 lakhs
= Rs. 5, 80, 425.


6.(D)
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 theyears 1995 and 1996.


7. (D)
1. The amount of exports of Company X (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 30, 60, 40, 70, 100, 50 and 120 respectively.
2. The amount of exports of Company Y (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 80, 40, 60, 60, 80, 100 and 140 respectively.
3. The amount of exports of Company Z (in crore Rs.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 60, 90,, 120, 90, 60, 80 and 100 respectively.
Average annual exports (in Rs. crore) of Company Y during the given period
=(1/7)* (80 + 40 + 60 + 60 + 80 + 100 + 140) =560/7= 80.

Average annual exports (in Rs. crore) of Company Z during the given period
=1/7* (60 + 90 + 120 + 90 + 60 + 80 + 100) =600/7
Required percentage {80/(600/7) x 100}= % 93.33%.


8.(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.


9.(C)
Average exports of the three Companies X, Y and Z in 1993
= Rs. (1/3) *(30 + 80 + 60) 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.60/3  crores
= Rs. 20 crores.


10.(C)
Average annual exports of Company Z during the given period
=(1/7)* (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 annualexports 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.
