On the basis of given graph in question ,
Total production of the company B in given years = 72000 + 90000 + 100000 = 262000 = 262 thousands
Number of given years = 3Required average production = Total production of the company B in given years Number of given years
Correct Option: A
On the basis of given graph in question ,
Total production of the company B in given years = 72000 + 90000 + 100000 = 262000 = 262 thousands

From the given bar diagram , we see
Production of buses by company A in 2009 = 64000
Production of buses by company A in 2010 = 70000
Increase in production = 70000  64000 = 6000Percentage increase ⇒ Increase in production × 100 Production of buses by company A Percentage increase in year 2010 ⇒ 6000 × 100 ≈ 9.4 64000
Production of buses by company A in 2010 = 70000
Production of buses by company A in 2011 = 77000
Increase in production = 77000  70000 = 7000Percentage increase in year 2011 ⇒ 7000 × 100 = 10 70000
Production of buses by company A in 2011 = 77000
Production of buses by company A in 2012 = 85000
Increase in production = 85000  77000 = 8000
Correct Option: B
From the given bar diagram , we see
Production of buses by company A in 2009 = 64000
Production of buses by company A in 2010 = 70000
Increase in production = 70000  64000 = 6000Percentage increase ⇒ Increase in production × 100 Production of buses by company A Percentage increase in year 2010 ⇒ 6000 × 100 ≈ 9.4 64000
Production of buses by company A in 2010 = 70000
Production of buses by company A in 2011 = 77000
Increase in production = 77000  70000 = 7000Percentage increase in year 2011 ⇒ 7000 × 100 = 10 70000
Production of buses by company A in 2011 = 77000
Production of buses by company A in 2012 = 85000
Increase in production = 85000  77000 = 8000Percentage increase in year 2012 ⇒ 8000 × 100 ≈ 10.4 77000
Production of buses by company A in 2012 = 85000
Production of buses by company A in 2013 = 93000
Increase in production = 93000  85000 = 8000Percentage increase in year 2013 ⇒ 8000 × 100 ≈ 9.5 85000
Hence , correct answer is 2012 year .
Direction: Study the following bar–diagram and answer the questions.
 The total units consumption in the year 2013 during these 5 months, in respect of the same in the previous year has been

View Hint View Answer Discuss in Forum
According to given bar graph , we have
Total consumption in 2012 = 2200 units
Total consumption in 2013 = 2300 units
Total Increase = 2300  2200 = 100 unitsPercentage increase = Total Increase × 100 Total consumption in 2012
Correct Option: E
According to given bar graph , we have
Total consumption in 2012 = 2200 units
Total consumption in 2013 = 2300 units
Total Increase = 2300  2200 = 100 unitsPercentage increase = Total Increase × 100 Total consumption in 2012 Percentage increase = 100 × 100 = 50 = 4.5 % 2200 11
 The maximum difference in the units consumption between these two years has been found in the month of

From the given bar diagram , we see that
In the month of July, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 600 – 550 = 50 units
In the month of August, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 700 – 500 = 200 units.
In the month of September, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 400 – 400 = 0 units.
In the month of October, Difference = Electric consumption in 2013  Electric consumption in 2012
Difference = 350 – 300 = 50 units.Correct Option: D
From the given bar diagram , we see that
In the month of July, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 600 – 550 = 50 units
In the month of August, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 700 – 500 = 200 units.
In the month of September, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 400 – 400 = 0 units.
In the month of October, Difference = Electric consumption in 2013  Electric consumption in 2012
Difference = 350 – 300 = 50 units.
In the month of November, Difference = Electric consumption in 2012  Electric consumption in 2013
Difference = 500 – 200 = 300 units
Hence , required month is November .
