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.

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.

The sales have increased by nearly 55% from 1995 to 2000 in the case of?
Lipsticks
Nail enamels
Talcum powders

Correct answer is D
The percentage increase from 1995 to 2000 for various products are:
Lipsticks = [ (48.17 - 20.15)/20.15 x 100 ] % = 139.06%
Nail enamels = [ (37.76 - 5.93)/5.93 x 100 ] % = 536.76%
Talcum powders = [ (29.14 - 14.97)/14.97 x 100 ] % = 94.66%
Shampoos = [ (12.21 - 7.88)/7.88 x 100 ] % = 54.95% ≈ 55%
Conditioners = [ (10.19 - 5.01)/5.01 x 100 ] % = 103.39%
