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)
1996
1997
1998
1999
Correct answer is B
The percentage rise/fall in production from the previous year for flavour Y during various years are:
In 1996 = [ (60 - 55)/55 x 100 ] % = 9.09% (increase)
In 1997 = [ (60 - 50)/60 x 100 ] % = 16.67% (decrease)
In 1998 = [ (55 - 50)/55 x 100 ] % = 10% (increase)
In 1999 = [ (55 - 50)/55 x 100 ] % = 9.09% (decrease)
In 2000 = [ (55 - 50)/50 x 100 ] % = 10% (increase)
Therefore Maximum change is decrease of 16.67% during 1997.

Production of Three Different Flavours X, Y and Z by a Company over the years (in lakh bottles)
50%
42%
33%
25%
Correct answer is C
Percentage decline in the production of flavour Z in 2000 as compared to the production in 1998
= [ (60 - 40)/60 x 100 ] %
= ( 20/60 x 100 ) %
= 33.33%
≈ 33%.
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)
50,000 bottles
80,000 bottles
240,000 bottles
500,000 bottles
Correct answer is D
Average production of flavour X in 1995, 1996 and 1997
= [ 1/3 x (50 + 40 + 55) ]
= ( 145/3 ) lakh bottles.
Average production of flavour Y in 1998, 1999 and 2000
= [ 1/3 x (55 + 50 + 55) ]
= ( 160/3 ) lakh bottles.
Therefore Difference = ( 160/3 - 145/3 )
= 15/3
= 5 lakh bottles
= 500,000 bottles.

Production of Three Different Flavours X, Y and Z by a Company over the years (in lakh bottles)
For which flavour was the average annual production maximum in the given period?
X only
Y only
Z only
X and Y
Correct answer is B
Average annual productions over the given period for various flavours are:
For Flavour X = [ 1/6 x (50 + 40 + 55 + 45 + 60 + 50) ] = 50 lakh bottles.
For Flavour Y = [ 1/6 x (55 + 60 + 50 + 55 + 50 + 55) ] = 54.17 lakh bottles.
For Flavour Z = [ 1/6 x (45 + 50 + 60 + 60 + 45 + 40) ] = 50 lakh bottles.
Therefore Maximum average production is for Flavour Y.
