Answers
1.(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.
2. (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%.
3.(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.
4.(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.
5.(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.
6.d;
Total number of passed students of College A =(100*220)/55 = 400
Number of girls passed = 45% of 400 = 180
Total number of passed students of College= (100*175)70 = 250
Number of girls passed = 30% of 250 = 75
Difference = 180 – 72 = 105
7.d;
For College A,
35% of girls = 70
Total student =(70*100)/35 = 200
For College B,
40% of girls = 70
Total student = (70*100)/40 = 175
Sum = 200 + 175 = 375
8.a;
Total students passed of College A in 2004 = 175
Total students passed of College B in 2002 = 150
Difference = 175 – 150 = 25
9.c;
Number of girls passed of College= (44*400)/100 =176 Number of girls passed of College B =(36*500)/100 = 180
% difference = [(180-176)/180]*100=20/9
10.d;
Number of girls passed from College A = Number of boys passed from College A = 200
Number of girls passed from College B = 48% = 240
Total passed=(240/200)*48=500
Number of boys passed=52% of 500 = 260
%=(260/200)*100=130%
