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
