b) 205/203

d) 230/207
e) None of these
Solutions:
1. A) Average production of laptop of model
LT1 in five years from 2006 to 2010
= (50000 + 60000 + 40000
+ 70000 + 30000)/5 = 250000/5 = 50000
Average production of Laptop
LT2 manufactured in last three year is
= (50000 + 60000 +
40000)/3 = 50000
Therefore, req ratio =
50000/50000 = 1
2. B) Production
of laptop LT1 in first two year is 50000 and 60000
% increase = (60000 –
50000)/50000 × 100 = 20%
Production of laptop LT2
in two year 2008 and 2009 is 50000 and 60000 respectively
% increase = (60000 –
50000)/50000 × 100 = 20 %
Therefore req. ratio = 1
3. B) From
line graph, we get
Laptop LT1 sold in 2009 =
100% = 70000
Laptop LT1 sold in 2010 =
70% = 70% of 30000 = 21000
Laptop LT2 sold in 2009 =
80% = 80% of 60000 = 48000
Laptop LT2 sold in 2010 =
100 % = 40000
Reqd avg = (70000 + 21000
+ 48000 + 40000)/4 = 44750
4. C) Production
of laptop LT1 in 2006 = 50000
Production of laptop LT1
in 2007 = 60000
Production of laptop LT1
in 2008 = 40000
Production of laptop LT1
in2009 = 70000
Production of laptop LT1
in 2010 = 30000
∑ = 250000
Sell of laptop LT1 in
2006 is 20% of 50000 = 10000
Sell of laptop LT1 in
2007 is 70% of 60000 = 42000
Sell of laptop LT1 in2008
is 50% of 40000 = 20000
Sell of laptop LT1 in2009
is 100% of 70000 = 70000
Sell of laptop LT1 in
2010 is 70% of 30000 = 21000
∑ = 163000
Required Difference =
250000 – 163000 = 87000
5. B) Sell
of laptop LT2 in 2009 = 80% of 60000 = 48000
Sell of laptop LT2 in
2010 = 100% = 40000
Increase = 8000
% increase = 8000/48000 ×
100% = 16.6%

6. D) Investment of unit Bhopal in year
2014 = Rs. 151
Investment of unit Bhopal
in year 2010 = Rs. 115
Investment % of unit
Bhopal to the total investment of all the units in the years is given below in
the table
Years

Investment %

2010

(115/598) × 100 = 19.23%

2011

(138/818) × 100 = 16.87%

2012

(139/832) × 100 = 16.70%

2013

(137/859) × 100 = 15.95%

2014

(151/901) × 100 = 16.76%

2015

(153/919) × 100 = 16.65%

Clearly, the required
year is 2013
7. A) Investment
of unit Haridwar in year 2011 = Rs. 129
Investment of unit
Gagdishpur in year 2011 = Rs. 133
Investment percent in
2011 of the total investment in all the given years together of each unit is
given below:
Name of unit

Investment percent

Gagdishpur

(133/744) × 100 = 17.88%

Bangalore

(141/830) × 100 = 16.99%

Bhopal

(138/833) × 100 = 16.57%

Goindwal

(126/816) × 100 = 15.44%

Haridwar

(129/823) × 100 = 15.67%

Jhansi

(151/881) × 100 = 17.14%

Hence, the required unit
is Gagdishpur.
8. D) Investment
of unit Goindwal in year 2010 = Rs. 99
Investment of unit Goindwal
in year 2013 = Rs. 146
So, required percent
increase = (146 – 99)/99 × 100 = 47.47%
9. B) Investment
of unit Jhansi in year 2012 = Rs. 146
Investment of unit Bangalore
in year 2012 = Rs. 146
Investment of unit Bangalore
in year 2015 = Rs. 145
Investment of unit
Gagdishpur, Bangalore and Bhopal in year 2012 = Rs. (126 + 146 + 139) = Rs. 411
Investment of unit
Bangalore, Bhopal and Goindwal in year 2015 = Rs. (145 + 153 + 153) = Rs. 451
So, required % = (451 –
411)/411 × 100 = 40/411 × 100 = 9.73%
10. E) Investment
of unit Bhopal in year 2014 = Rs. 151
Total investment of units
Bhopal, Goindwal and Haridwar in year 2012 = Rs. (139 + 133 + 142) = Rs. 414
Total investment of units
Bhopal, Goindwal and Haridwar in year 2014 = Rs. (151 + 159 + 150) = Rs. 460
So, required ratio =
414/460 = 207/230
