According to given bar graph , we have
The production of State C in 2003- 2004 = 6
The production of State C in 2005- 2006 = 15Required answer = The production of State C in 2003- 2004 The production of State C in 2005- 2006
Correct Option: D
According to given bar graph , we have
The production of State C in 2003- 2004 = 6
The production of State C in 2005- 2006 = 15Required answer = The production of State C in 2003- 2004 The production of State C in 2005- 2006 Required answer = 6 = 0.4 15

On the basis of given graph in question ,
Sum of demand of companies B and D = 1200 + 600 = 1800
Number of companies = 2Average demand of companies B and D = Sum of demand of companies B and D = 1800 = 900 Number of companies 2
Sum of production of companies B and D = 2700 + 1800 = 4500
Number of companies = 2Average production of companies B and D = Sum of production of companies B and D Number of companies
Correct Option: B
On the basis of given graph in question ,
Sum of demand of companies B and D = 1200 + 600 = 1800
Number of companies = 2Average demand of companies B and D = Sum of demand of companies B and D = 1800 = 900 Number of companies 2
Sum of production of companies B and D = 2700 + 1800 = 4500
Number of companies = 2Average production of companies B and D = Sum of production of companies B and D Number of companies Average production of companies B and D = 4500 = 2250 2
∴ Required ratio = 900 : 2250 = 2 : 5
- Demand of company D is approximately what percent of demand of company E ?

According to given bar graph , we have
Demand of company D = 600
Demand of company E = 2500Required percentage = Demand of company D × 100 Demand of company E
Correct Option: C
According to given bar graph , we have
Demand of company D = 600
Demand of company E = 2500Required percentage = Demand of company D × 100 Demand of company E Required percentage = 600 × 100 = 24% 2500

On the basis of given graph in question ,
Total demand = 3300 + 1200 + 3000 + 600 + 2500
Number of companies = 5Average demand = 3300 + 1200 + 3000 + 600 + 2500 5 Average demand = 10600 = 2120 5
Total production = 2200 + 2700 + 1500 + 1800 + 1000
Number of companies = 5Average production = 2200 + 2700 + 1500 + 1800 + 1000 5
Correct Option: C
On the basis of given graph in question ,
Total demand = 3300 + 1200 + 3000 + 600 + 2500
Number of companies = 5Average demand = 3300 + 1200 + 3000 + 600 + 2500 5 Average demand = 10600 = 2120 5
Total production = 2200 + 2700 + 1500 + 1800 + 1000
Number of companies = 5Average production = 2200 + 2700 + 1500 + 1800 + 1000 5 Average production = 9200 = 1840 5
&there; Required difference = Average demand : Average production
&there; Required difference = 2120 – 1840 = 280
