A soft drink company prepares drinks of three different flavours - X, Y and Z. The production of three flavours over a period of six years has been expressed in the bar graph provided below.

Production of Three Different Flavours X, Y and Z by a Company over the years (in lakh bottles) 1.
The total production of flovour Z in 1997 and 1998 is what percentage of the total production of flavour X in 1995 and 1996?
96.67%
102.25%
115.57%
133.33%
Explanation:

Required percentage
 = (60 + 60) x 100 % (50 + 40)
 = 120 x 100 % 90
= 133.33%.

2.
For which flavour was the average annual production maximum in the given period?
X only
Y only
Z only
X and Y
Explanation:

Average annual productions over the given period for various flavours are:

 For Flavour X = 1 x (50 + 40 + 55 + 45 + 60 + 50) = 50 lakh bottles. 6

 For Flavour Y = 1 x (55 + 60 + 50 + 55 + 50 + 55) = 54.17 lakh bottles. 6

 For Flavour Z = 1 x (45 + 50 + 60 + 60 + 45 + 40) = 50 lakh bottles. 6 Maximum average production is for Flavour Y.

3.
What is the difference between the average production of flavour X in 1995, 1996 and 1997 and the average production of flavour Y in 1998, 1999 and 2000?
