The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.
Percentage of Six different types of Cars manufactured by a Company over Two Years
140,000
132,000
117,000
105,000
Correct answer is B
If the percentage production of P type cars in 2001
= Percentage production of P type cars in 2000
= 30%.
then, number of P type cars produced in 2001
= 30% of 440,000
= 132,000.

Total number of cars of models P, Q and T manufactured in 2000 is?
245,000
227,500
210,000
192,500
Correct answer is C
Analysis of the graph:
We shall first determine the number of cars of each model produced by the Company during the two years:
In 2000 : Total number of cars produced = 3,50,000.
P = (30 - 0)% of 350,000 = 30% of 350,000 = 105,000.
Q = (45 - 30)% of 350,000 = 15% of 350,000 = 52,500.
R = (65 - 45)% of 350,000 = 20% of 350,000 = 70,000.
S = (75 - 65)% of 350,000 = 10% of 350,000 = 35,000.
T = (90 - 75)% of 350,000 = 15% of 350,000 = 52,500.
U = (100 - 90)% of 350,000 = 10% of 350,000 = 35,000.
In 2001 : Total number of cars produced = 4,40,000.
P = (40 - 0)% of 440,000 = 40% of 440,000 = 176,000.
Q = (60 - 40)% of 440,000 = 20% of 440,000 = 88,000.
R = (75 - 60)% of 440,000 = 15% of 440,000 = 66,000.
S = (85 - 75)% of 440,000 = 10% of 440,000 = 44,000.
T = (95 - 85)% of 440,000 = 10% of 440,000 = 44,000.
U = (100 - 95)% of 440,000 = 5% of 440,000 = 22,000.
Total number of cars of models P, Q and T manufacture in 2000
= (105000 + 52500 + 52500)
= 210,000.
The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.

What was the difference in the number of Q type cars produced in 2000 and that produced in 2001?
35,500
27,000
22,500
17,500
Correct answer is A
Total number of Q type cars produced in 2001
=(60 - 40)% of 4,40,000 = 88,000.
Total number of Q type cars produced in 2000
=(45 - 30)% of 3,50,000 = 52,500.
Therefore Required difference = (88000 - 52500) = 35,500.
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.
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%
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%.
