## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following graph gives Sales, Expense and Capital of a company for a period of five years 1994 to 1998. Read the graph and answer the following questions.

1. What has been the simple average growth rate per annum of expense between 1994 and 1998?

1. According to given bar graph , we have
Growth rate per annum of expense for :

 1995 → 100 × 100 = 100 % 300 3

1996 → 0%
 1997 → 200 × 100 = 50% 400

 1998 → 100 × 100 = 50 % 600 3

##### Correct Option: A

According to given bar graph , we have
Growth rate per annum of expense for :

 1995 → 100 × 100 = 100 % 300 3

1996 → 0%
 1997 → 200 × 100 = 50% 400

 1998 → 100 × 100 = 50 % 600 3

 Required average = [ ( 100/300 ) + 50 + ( 50/3 ) + 0 ] = 25% 4

Direction: The following questions are based on the bar graph. Read the graph and answer the questions.

1. By what amount (in \$ million) has the expenditure increased over the period 1993-94 to 1997-98?

1. From the given bar diagram , we see
Total expenditure in 1997-98 = 8800 million
Total expenditure in 1993-94 = 5100 million
Required increase = Total expenditure in 1997-98 - Total expenditure in 1993-94

##### Correct Option: D

From the given bar diagram , we see
Total expenditure in 1997-98 = 8800 million
Total expenditure in 1993-94 = 5100 million
Required increase = Total expenditure in 1997-98 - Total expenditure in 1993-94
∴ Required increase = (8800 – 5100) million = 3700 million

1. In order to make a profit of 10%. What should have been the gross traffic receipts (in \$ million) in 1994-95, total expenditure remaining the same?

1. On the basis of given graph in question ,

 Profit percent = Gross Traffic profit - Total expenditure × 100 Gross Traffic profit

 ⇒ Total expenditure Gross Traffic profit

 = 1 - 10 = 0.9 100

##### Correct Option: C

On the basis of given graph in question ,

 Profit percent = Gross Traffic profit - Total expenditure × 100 Gross Traffic profit

 ⇒ Total expenditure Gross Traffic profit

 = 1 - 10 = 0.9 100

According to question,
Total expenditure = 5800
 ∴ Gross Traffic profit = 5800 = \$ 6444 million 0.9

1. In which year was the profit as a percentage of gross traffic receipts the highest?

1. From the given bar diagram , we see
In year 1997-98 ,
Gross Traffic Receipt = 9400
Total expenditure = 8800
Change = 9400 - 8800 = 600

 Profit percent of Gross Traffic Receipt = 600 × 100 = 6.38% 9400

In year 1995-1996 ,
Gross Traffic Receipt = 7500
Total expenditure = 5900
Change = 7500 - 5900 = 1600

##### Correct Option: C

From the given bar diagram , we see
In year 1997-98 ,
Gross Traffic Receipt = 9400
Total expenditure = 8800
Change = 9400 - 8800 = 600

 Profit percent of Gross Traffic Receipt = 600 × 100 = 6.38% 9400

In year 1995-1996 ,
Gross Traffic Receipt = 7500
Total expenditure = 5900
Change = 7500 - 5900 = 1600
 Profit percent of Gross Traffic Receipt = 1600 × 100 = 21.33% 7500

1. If profit » gross traffic receipts— total expenditure, then in 1996- 97, what percentage of gross traffic receipts is the profit made?

1. According to given bar graph , we have
Gross Traffic Receipt = 8500
Total expenditure = 8000
Profit in year 1996-97 = Gross Traffic Receipt – Total expenditure
Profit in year 1996-97 = 8500 – 8000 = 500
Therefore,

 Profit percent of Gross Traffic Receipt = Profit in year 1996-97 × 100 Gross Traffic Receipt

##### Correct Option: A

According to given bar graph , we have
Gross Traffic Receipt = 8500
Total expenditure = 8000
Profit in year 1996-97 = Gross Traffic Receipt – Total expenditure
Profit in year 1996-97 = 8500 – 8000 = 500
Therefore,

 Profit percent of Gross Traffic Receipt = Profit in year 1996-97 × 100 Gross Traffic Receipt

 Profit percent of Gross Traffic Receipt = 500 × 100 = 5.9% 8500
