a) Alpha   b) Omega and Alpha       c) Beta and Omega   d) Beta only  e)None of these
Explanation:
Alpha = 2800 – 1980 =820
Beta = 2750- 2900 =-250
Gamma = 2600 – 2250= 350
Omega = 1250 – 1485 = -235
Theta = 1950-3650 = - 1700
Change may be increase or decrease. So model Theta has highest change of production in 2014 over 2013.

2.  In which year does the production in model Omega showed the highest percentage increase over the previous year?
a) 2012                   b) 2013         c) 2014                   d) 2015    e)2015
Explanation :
% Increase in 2012 = $\frac{1800-1400}{1400}$ x 100 % =28.57%

% Increase in 2014= $\frac{1485-1250}{1250}$ x 100% =18.8%

% Increase in 2015 =$\frac{1680-1485}{1485}$ x 100% =13.13%

% increase in 2016 =  $\frac{1800-1680}{1680}$ x 100% = 7.14%

The highest percentage increase in the production of model Omega is in 2012 over the previous year

3. The production of which model increase continuously from 2013 to 2016?
a) Alpha only           b) Beta and Gamma           c) Both a and b
d)Omega                 e) None of the above
Explanation :
Model Omega only has continuous  increase in its production from 2013 to 2016.

4. In which year did the productions of Theta fall for the first time?
a)2014                 b) 2015         c) 2016         d) 2012         e)2013
Explanation :
For the first time, in 2014, production is decreased to 1950 from 3650.

5. In 2011, which of the following models contributed approximately 25% of the total productions of all the five models?
a) Alpha                  b) Mango       c) Omega                d) Gamma     e) Theta
Explanation :
Total production of all five models in 2011 = 2200+2500+2100+1400+2800 =11000

% contribution  of Alpha model in 2011 = $\frac{2200}{11000}$ x 100% = 20%

% contribution  of Beta model in 2011 = $\frac{2500}{11000}$ x 100% = 22.7%

% contribution  of Gamma model in 2011 = $\frac{2100}{11000}$ x 100% = 19.09%

% contribution  of Omega model in 2011 = $\frac{1400}{11000}$ x 100% = 12.72%

% contribution  of Theta model in 2011 = $\frac{2800}{11000}$ x 100% = 25.45%

In 2011 , Theta model contributed approximately 25% of the total productions of all the five models .
