Total production of flavour Z in 2007 and 2008 = 60 + 60 = 120 lakh bottles
Total production of flavour X in 2005 and 2006 = 50 + 40 = 90 lakh bottles
∴ Reqd. % =120/90 × 100% = 133.33%

X production over the years = 50 + 40 + 55 + 45 + 60 + 50 = 300
Y production over the years = 55 + 60 + 50 + 55 + 50 + 55 = 325
Z production over the years = 45 + 50 + 60 + 60 + 45 + 40 = 300
Just from addition of the given values we can infer that the greatest average will be of company Y because the sum of values is the highest for it.

Average production of flavour X in 2005, 2006 and 2007
= 1/3× (50 + 40 + 55)
= (145/3) lakh bottles
Average production of flavour Y in 2008, 2009 and 2010
= 1/3× (55 + 50 + 55)
= (160/3) lakh bottles 3
∴ Reqd. difference = (160/3 -145/3) = 15/3
= 5 lakh bottles

Percentage decline in the production of flavour Z in 2010 as compared to the production in 2008
= (60 – 40)/60 × 100%
=20/60 × 100 = 33.33% ≈ 33%

In 2007 we can clearly observe that the fall in production from the previous year is the maximum.

Since, we have information regarding per cent increase or decrease in the profits during the period
2007 to 2009, we can't answer the question given.
Note: Profit in a particular year depends on revenue earned and expenditure occurred in that specific year.
Without these pieces of information we can't really find the profit in numeric terms for a particular year.

We have, profit
=(per cent profit × Expenditure)/100
Therefore, by using the this formula, the reqd. ratio of profits
=(2 × 30)/100 : (3 × 20)/100 : (4 × 10)/100
100 100 100
= 6 : 6 : 4 = 3 : 3 : 2

We have no information regarding the total profits of different companies in the year 2008, Hence, the question can't be answered.

Suppose, the expenditures of the company Elite in the years 2007, 2008 and 2009 are E7, E8 and
E9 respectively, then
18% of E7 = 16% of E8= 12% of E9
E7 : E8 : E9 =
1/18:1/16:1/12
18 :16: 12
E7 : E8 : E9 = 8 : 9 : 12

It is obvious from the given bar chart that total per cent profit during the three years in maximum for company Apple and therefore its average is maximum.
