## Introduction to Data Interpretation

#### Data Interpretation

Direction: The graph shows the result of 10th class students of a school for 4 years. Study the graph and answer the questions : 1. The number of students appeared for the 10th class exam in the year 2002 is

1. As per the given bar graph , we have
Required number of students in 2002 = 15 + 60 + 120

##### Correct Option: B

As per the given bar graph , we have
Required number of students in 2002 = 15 + 60 + 120 = 195

Direction: The following Bar Diagram depicts figures for some agricultural imports from January-May, 2008. Answer (as closely as possible) the questions using the date provided here 1. What was the total cost (in \$) of wheat import in March?

1. According to given bar graph , we have
Total Wheat import in March = 36 tonnes
Cost of Wheat = \$ 156

##### Correct Option: B

According to given bar graph , we have
Total Wheat import in March = 36 tonnes
Cost of Wheat = \$ 156
Required cost of wheat = 36 × 156 = \$ 5616

1. What is the average cost of potato import in February and March?

1. As per the given bar graph , we have
Potato import in February = 33 tonnes
Potato import in March = 33 tonnes
Cost of potato = \$ 120

 Required average price = 1 (33 × 120 × + 33 × 120) 2

##### Correct Option: A

As per the given bar graph , we have
Potato import in February = 33 tonnes
Potato import in March = 33 tonnes
Cost of potato = \$ 120

 Required average price = 1 (33 × 120 × + 33 × 120) 2

 Required average price = 1 × 120 × 66 = \$ 3960 2

Direction: Study the graph and answer the following questions. 1. How many times of the production of company A is that of the company D?

1. As per the given bar graph , we have
The production of company A = 1500
The production of company D = 2700

 Required answer = The production of company A The production of company D

##### Correct Option: C

As per the given bar graph , we have
The production of company A = 1500
The production of company D = 2700

 Required answer = The production of company A The production of company D

 Required answer = 2700 = 9 = 1.8 1500 5

1. What is the ratio of companies having more demand than production to those having more production than demand?

1. According to given bar graph , we have
Number of companies having more demand than production ( A , C and E companies ) = 3
Number of companies having more production than demand ( B and D companies ) = 2
Required ratio = Number of companies having more demand than production : Number of companies having more production than demand

##### Correct Option: D

According to given bar graph , we have
Number of companies having more demand than production ( A , C and E companies ) = 3
Number of companies having more production than demand ( B and D companies ) = 2
Required ratio = Number of companies having more demand than production : Number of companies having more production than demand
∴ Required ratio = 3 : 2
