## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the bar chart given below and answer the following questions : 1. The companies M and N together had a percentage of profit/loss of :

1. On the basis of given graph in question ,
Total income of companies M and N = Rs. (35 + 50) crores = Rs. 85 crores
Total expenditure of companies M and N = Rs. (45 + 40) crores = Rs. 85 crores

##### Correct Option: A

On the basis of given graph in question ,
Total income of companies M and N = Rs. (35 + 50) crores = Rs. 85 crores
Total expenditure of companies M and N = Rs. (45 + 40) crores = Rs. 85 crores
Profit/Loss = Total income - Total expenditure = 85 - 85 = Rs. 0
Therefore , there is no loss and no profit .

1. The company earning the maximum percentage of profit in the year 2001 is :

1. From the given bar diagram , we see
Income of company Q in 2001 = Rs. 40 crores
Expenditure of company Q in 2001 = Rs. 30 crores
Profit of Q = 40 - 30 = 10 crores

 Profit percent of company Q = 10 × 100 30

##### Correct Option: A

From the given bar diagram , we see
Income of company Q in 2001 = Rs. 40 crores
Expenditure of company Q in 2001 = Rs. 30 crores
Profit of Q = 40 - 30 = 10 crores

 Profit percent of company Q = 10 × 100 30

 Profit percent of company Q = 100 = 33 1 % 3 3

1. If the income of company Q in 2001 was 10% more than that in 2000 and the company had earned a profit of 20% in 2000, then its expenditure in 2000 (in crores Rs.) was :

1. As per the given bar graph ,
Income of company Q in 2001 = Rs. 40 crores
From question , we have

 Income of company Q in 2000 = 100 × 40 = Rs. 400 crores 110 11

If expenditure in 2000 be Rs. y crores,
 Profit % = Income – Expenditure × 100 Expenditure

 Profit % = ( 400 / 11 ) - y × 100 y

 ⇒ 20 = 1 = 400 - 11y 100 5 11y

##### Correct Option: E

As per the given bar graph ,
Income of company Q in 2001 = Rs. 40 crores
From question , we have

 Income of company Q in 2000 = 100 × 40 = Rs. 400 crores 110 11

If expenditure in 2000 be Rs. y crores,
 Profit % = Income – Expenditure × 100 Expenditure

 Profit % = ( 400 / 11 ) - y × 100 y

 ⇒ 20 = 1 = 400 - 11y 100 5 11y

⇒ 5 × 400 – 55y = 11y
⇒ 66y = 2000
 ⇒ y = 2000 = Rs. 30.30 crores 66

Hence , expenditure in 2000 be Rs. 30.30 crores .

1. In 2001, the approximate percentage of profit/loss of all the five companies taken together is equal to

1. On the basis of given graph in question ,
Total income = Rs. (35 + 50 + 40 + 40 + 50) crores = Rs. 215 crores
Total expenditure = Rs. (45 + 40 + 45 + 30 + 45) crores = Rs. 205 crores

 ∴ Profit percent = Income – Expenditure × 100 Expenditure

##### Correct Option: E

On the basis of given graph in question ,
Total income = Rs. (35 + 50 + 40 + 40 + 50) crores = Rs. 215 crores
Total expenditure = Rs. (45 + 40 + 45 + 30 + 45) crores = Rs. 205 crores

 ∴ Profit percent = Income – Expenditure × 100 Expenditure

 Profit percent = 215 – 205 × 100 205

 Profit percent = 1000 = 4.88% 205

Direction: Study the following bar diagram carefully and answer the four questions. 1. The ratio of the average production of company A in 2009 and 2010 to the average production of company B in the same years is

1. As per the given bar graph , we have
Production of company A in 2009 = 64 thousands
Production of company A in 2010 = 70 thousands
Production of company B in 2009 = 72 thousands
Production of company B in 2010 = 80 thousands
Number of years = 2

##### Correct Option: C

As per the given bar graph , we have
Production of company A in 2009 = 64 thousands
Production of company A in 2010 = 70 thousands
Production of company B in 2009 = 72 thousands
Production of company B in 2010 = 80 thousands
Number of years = 2
Required ratio Required ratio = 67 : 76
