As per the given bar graph , we have
Total production = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
Total demand = 3000 + 600 + 2500 + 1200 + 3300 = 10600
Number of given companies = 5
Required difference = Average demand - Average production
Required difference = 1 (10600 - 9200)
5

Correct Option: B

As per the given bar graph , we have
Total production = 1500 + 1800 + 1000 + 2700 + 2200 = 9200
Total demand = 3000 + 600 + 2500 + 1200 + 3300 = 10600
Number of given companies = 5
Required difference = Average demand - Average production
Required difference = 1 (10600 - 9200)
5

Required difference = 1 × 1400 = 280

On the basis of given graph in question ,
Demand for company C = 2500
Demand for company B = 600
According to the question,
x% of 2500 = 600
2500 × x = 600
100

⇒ 25x = 600

Correct Option: A

On the basis of given graph in question ,
Demand for company C = 2500
Demand for company B = 600
According to the question,
x% of 2500 = 600
2500 × x = 600
100

⇒ 25x = 600
⇒ x = 600 = 24

As per the given bar graph , we have
Demand of company A = 3000
Production of company A = 1500
Difference between demand and production of company A = 3000 – 1500 = 1500
Demand of company D = 2700
Production of company D = 1200

Correct Option: B

As per the given bar graph , we have
Demand of company A = 3000
Production of company A = 1500
Difference between demand and production of company A = 3000 – 1500 = 1500
Demand of company D = 2700
Production of company D = 1200
Difference between production and demand of company D = 2700 – 1200 = 1500
Hence , the most suitable company is D.

Direction: Study the bar chart given below and answer the following questions :

For company R, if the expenditure had increased by 20% in the year 2001 from the year 2000 and the company had earned profit of 10% in 2000, the company’s income in 2000 was (in crore Rs.) :

1. 41.67
1. 35.75
1. 37.25
1. 38.5
1. None of these

According to given bar graph , we have
Expenditure of company R in 2001 = Rs. 45 crores
If expenditure had increased by 20% , then
Expenditure of company R in 2000 = 45 × 100 = Rs. 37.5 crores
120

Let the income of company in 2000 be Rs. y crores.
∴ 10 = y - 37.5 × 100
37.5

Correct Option: E

According to given bar graph , we have
Expenditure of company R in 2001 = Rs. 45 crores
If expenditure had increased by 20% , then
Expenditure of company R in 2000 = 45 × 100 = Rs. 37.5 crores
120

Let the income of company in 2000 be Rs. y crores.
∴ 10 = y - 37.5 × 100
37.5

⇒ y – 37.5 = 37.5 × 10 = 3.75
100

⇒ y = 37.5 + 3.75 = Rs. 41.25 crores
