## Introduction to Data Interpretation

#### Data Interpretation

Direction: A constituency is divided in four regions A, B, C and D. Two candidates X and Y contested the last election from that constituency. The adjoining graph gives the break–up of voting in the four regions. Study the graph and answer the following questions. 1. Nearly what percentage of his total votes did X receive from region B?

1. According to given bar graph , we have
In region B , X gets votes = 73
Total votes received by X = 45 + 73 + 51 + 56 = 225

##### Correct Option: C

According to given bar graph , we have
In region B , X gets votes = 73
Total votes received by X = 45 + 73 + 51 + 56 = 225

 Required percent = 73 × 100 ≈ 32 225

1. In region B, Y gets A% more votes than X. Find the value of A.

1. As per the given bar graph , we have
n region B, Y gets votes = 88

 Required percent = 88 - 73 × 100 73

##### Correct Option: B

As per the given bar graph , we have
n region B, Y gets votes = 88

 Required percent = 88 - 73 × 100 73

 Required percent = 1500 ≈ 21% 73

Hence , required answer is 21% .

1. Approximately how much percent of voters did not caste their votes?

1. On the basis of given graph in question ,
Number of voters who did not vote = 1 + 9 + 5 + 8 = 23
Total number of votes = (41 + 97 + 52 + 59) + 225 = 474

 Required percent = Number of voters who did not vote × 100 Total number of votes

##### Correct Option: A

On the basis of given graph in question ,
Number of voters who did not vote = 1 + 9 + 5 + 8 = 23
Total number of votes = (41 + 97 + 52 + 59) + 225 = 474

 Required percent = Number of voters who did not vote × 100 Total number of votes

 Required percent = 23 × 100 ≈ 4.9% 474

1. Approximately how much percent of voters voted in favour of X?

1. According to given bar graph , we have
Total votes received by X = 45 + 73 + 51 + 56 = 225
Total votes in four regions A, B, C and D = (41 + 97 + 52 + 59) + 225 = 474

 ∴ Required percent = Total votes received by X × 100 Total votes in four regions A, B, C and D

##### Correct Option: B

According to given bar graph , we have
Total votes received by X = 45 + 73 + 51 + 56 = 225
Total votes in four regions A, B, C and D = (41 + 97 + 52 + 59) + 225 = 474

 ∴ Required percent = Total votes received by X × 100 Total votes in four regions A, B, C and D

 Required percent = 225 × 100 ≈ 47.5% 474

Direction: The bar graph provided below gives the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years. Study the bar chart and answer the following questions. 1. The difference between the production of company Z in 1998 and company Y in 1996 is :

1. On the basis of given graph in question ,
Production of company Z in 1998 = 45 lakh tonnes
Production of company Y in 1996 = 25 lakh tonnes
Required difference = Production of company Z in 1998 - Production of company Y in 1996

##### Correct Option: D

On the basis of given graph in question ,
Production of company Z in 1998 = 45 lakh tonnes
Production of company Y in 1996 = 25 lakh tonnes
Required difference = Production of company Z in 1998 - Production of company Y in 1996
Required difference = (45 – 25) lakh tonnes = 2000000 tonnes
