## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following graph shows production (in thousands) of two types (P and Q) of vehicles by a factory over the years 2009 to 2014. Study the graph and answer the given questions.

1. In how many of the given years, was the production of Type P vehicles of the company more than the average production of this type vehicles in the given years?

1. On the basis of given graph in question ,
Sum of production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275
Total number of given years = 6

 Average production of type P vehicles = Sum of production of type P vehicles Total number of given years

 Average production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275 6

##### Correct Option: A

On the basis of given graph in question ,
Sum of production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275
Total number of given years = 6

 Average production of type P vehicles = Sum of production of type P vehicles Total number of given years

 Average production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275 6

 Average production of type P vehicles = 1200 = 200 thousands 6

The production of Type P vehicles of the company more than the average production of this type vehicles is 200 thousands .
So , Required years ⇒ 2012, 2013 and 2014
Hence , required answer is 3 .

Direction: In the following questions, the Graph shows the demand and production of different companies. Study the graph and answer the questions.

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

1. As per the given line graph in question , we can see
Companies having more demand than production ⇒ A and D = 2
Companies having more production than demand ⇒ B, C, E and F = 4
∴ Required ratio = Companies having more demand than production : Companies having more production than demand

##### Correct Option: B

As per the given line graph in question , we can see
Companies having more demand than production ⇒ A and D = 2
Companies having more production than demand ⇒ B, C, E and F = 4
∴ Required ratio = Companies having more demand than production : Companies having more production than demand
∴ Required ratio = 2 : 4 = 1 : 2

1. The production of company A is approximately what per cent of the demand of company C ?

1. On the basis of given graph in question , we have
The production of company A = 1450
The demand of company C = 2600

 Required percent = The production of company A × 100 The demand of company C

 Required percent = 1450 × 100 2600

##### Correct Option: D

On the basis of given graph in question , we have
The production of company A = 1450
The demand of company C = 2600

 Required percent = The production of company A × 100 The demand of company C

 Required percent = 1450 × 100 2600

 Required percent = 1450 = 55.8 26

1. What is the difference between the average demand and the average production of the companies (in lakh tonnes)? [Approximately]

1. According to given graph in question ,
Sum of demand of the all given companies = 2100 + 3150+ 2600+ 5000+ 2800+ 3300
Total number of companies = 6
And Sum of production of the all given companies = 1450+ 3660+ 3100 + 4200 + 3700 + 4500

 Average demand = (2100 + 3150+ 2600+ 5000+ 2800+ 3300) lakh tonnes 6

 Average demand = 18950 lakh tonnes 6

 Average production = (1450+ 3660+ 3100 + 4200 + 3700 + 4500) lakh tonnes 6

 Average production = 20610 lakh tonnes 6

##### Correct Option: C

According to given graph in question ,
Sum of demand of the all given companies = 2100 + 3150+ 2600+ 5000+ 2800+ 3300
Total number of companies = 6
And Sum of production of the all given companies = 1450+ 3660+ 3100 + 4200 + 3700 + 4500

 Average demand = (2100 + 3150+ 2600+ 5000+ 2800+ 3300) lakh tonnes 6

 Average demand = 18950 lakh tonnes 6

 Average production = (1450+ 3660+ 3100 + 4200 + 3700 + 4500) lakh tonnes 6

 Average production = 20610 lakh tonnes 6

 Required difference = 20610 - 18950 6 6

 Required difference = 1660 = 276.7 lakh tonnes 6

∴ Required answer = 275 lakh tonnes

1. The demand of company B is what percentage of the production of company F?

1. As per the given graph in question ,
The demand of company B = 3150 units
The production of company F = 4500 units

 Required percentage = The demand of company B × 100 The production of company F

##### Correct Option: B

As per the given graph in question ,
The demand of company B = 3150 units
The production of company F = 4500 units

 Required percentage = The demand of company B × 100 The production of company F

 Required percentage = 3150 × 100 = 70 % 4500
