## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar-graph given below shows the percentage distribution of total expenditures of a company under various expense heads during 2013. Study the graph and answer the given questions.

1. If the expenditure on advertisement is 2.10 million, then the difference between the expenditures on transport and taxes is

1. According to given bar graph , we have
Percentage of the expenditure on taxes = 10%
Percentage of the expenditure on transport = 12.5%
Difference in percentage for expenditure on transport and taxes = 12.5 – 10 = 2.5%
∵ 15 % = \$ 2.10 million

##### Correct Option: B

According to given bar graph , we have
Percentage of the expenditure on taxes = 10%
Percentage of the expenditure on transport = 12.5%
Difference in percentage for expenditure on transport and taxes = 12.5 – 10 = 2.5%
∵ 15 % = \$ 2.10 million

 ∴ 2.5% = 2.10 × 2.5 = \$ 0.35 billion 15

Required answer = \$ 35 million

1. The ratio of the total expenditure on infrastructure and transport to the total expenditure on taxes and interest on loans is

1. From the given bar diagram , we see
The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loans

##### Correct Option: D

From the given bar diagram , we see
The total expenditure on infrastructure and transport = 20 + 12.5 = 32.5
The total expenditure on taxes and interest on loans = 10 + 17.5 = 27.5
Required ratio = The total expenditure on infrastructure and transport : The total expenditure on taxes and interest on loans
∴ Required ratio = 32.5 : 27.5 = 13 : 11

1. The expenditure on the interest on loans is what percent more than the expenditure on transport?

1. On the basis of given graph in question ,
The expenditure on the interest on loans = 17.5
The expenditure on transport = 12.5
Change in expenditure = 17.5 - 12.5 = 5

 Required percent = Change in expenditure × 100 The expenditure on transport

 Required percent = 5 × 100 12.5

##### Correct Option: D

On the basis of given graph in question ,
The expenditure on the interest on loans = 17.5
The expenditure on transport = 12.5
Change in expenditure = 17.5 - 12.5 = 5

 Required percent = Change in expenditure × 100 The expenditure on transport

 Required percent = 5 × 100 12.5

 Required percent = 500 = 40% 12.5

Direction: The distribution of fruit consumption in a sample of 72 seventeen - year - old girls is given in the graph below. Study the graph and answer the questions.

1. How many of these girls ate more than two servings but less than six servings per day?

1. According to given bar graph , we have
Number of girls ate more than two servings but less than six servings per day are 10 , 8 and 5 .

##### Correct Option: C

According to given bar graph , we have
Number of girls ate more than two servings but less than six servings per day are 10 , 8 and 5 .
So , Required number of girls = 10 + 8 + 5 = 23

1. What percent of these girls ate six or more servings per day?

1. As per the given bar graph , we have
Number of girls who ate six or more servings per day = 3 + 3 + 3 = 9
Total number of girls = 72

 ∴ Required percentage = Number of girls who ate six or more servings per day × 100 Total number of girls

##### Correct Option: A

As per the given bar graph , we have
Number of girls who ate six or more servings per day = 3 + 3 + 3 = 9
Total number of girls = 72

 ∴ Required percentage = Number of girls who ate six or more servings per day × 100 Total number of girls

 ∴ Required percentage = 9 × 100 = 25 = 12.5% 72 2
