## Introduction to Data Interpretation

#### Data Interpretation

1. In which of the following years, the percent increase of deficit was highest over its preceding year?

1. According to given bar graph in question ,
The deficit in 1992-93 = 3600
The deficit in 1991-92 = 2600
Increase = 3600 - 2600 = 1000

 Percentage increase in 1992-93 ⇒ 1000 × 100 ≈ 38% 2600

The deficit in 1990-91 = 2800
The deficit in 1989-90 = 2100
Increase = 2800 - 2100 = 700
 Percentage increase in 1990-91 ⇒ 700 × 100 ≈ 33.3% 2100

The deficit in 1988-89 = 3100
The deficit in 1987-88 = 2200
Increase = 3100 - 2200 = 900

##### Correct Option: D

According to given bar graph in question ,
The deficit in 1992-93 = 3600
The deficit in 1991-92 = 2600
Increase = 3600 - 2600 = 1000

 Percentage increase in 1992-93 ⇒ 1000 × 100 ≈ 38% 2600

The deficit in 1990-91 = 2800
The deficit in 1989-90 = 2100
Increase = 2800 - 2100 = 700
 Percentage increase in 1990-91 ⇒ 700 × 100 ≈ 33.3% 2100

The deficit in 1988-89 = 3100
The deficit in 1987-88 = 2200
Increase = 3100 - 2200 = 900
 Percentage increase in 1988-89 ⇒ 900 × 100 ≈ 41% 2200

1. Percentage increase in deficit in 1993-94 as compared to deficit in 1989-90 was

1. According to given bar graph in question ,
The deficit in 1993-94 = 4200
The deficit in 1989-90 = 2100
Increase = 4200 - 2100

 Percentage increase = Increase × 100 The deficit in 1989-90

##### Correct Option: C

According to given bar graph in question ,
The deficit in 1993-94 = 4200
The deficit in 1989-90 = 2100
Increase = 4200 - 2100

 Percentage increase = Increase × 100 The deficit in 1989-90

 Percentage increase = 2100 × 100 = 100% 2100

1. The deficit in 1993-94 was roughly how many times the deficit in 1990-91?

1. As per the given bar graph in question ,
The deficit in 1993-94 = 4200
The deficit in 1990-91 = 2800

 Required answer = The deficit in 1993-94 The deficit in 1990-91

##### Correct Option: B

As per the given bar graph in question ,
The deficit in 1993-94 = 4200
The deficit in 1990-91 = 2800

 Required answer = The deficit in 1993-94 The deficit in 1990-91

 ∴ Required answer = 4200 = 1.5 2800

Direction: Given here is a graph showing the number of workers with their daily payment by a workshop. Study the graph and answer questions based on this graph.

1. The total daily payment made to the group which contains 9 workers is (in \$)

1. According to given bar graph in question ,
The daily payment made to each worker which contains 9 workers = \$ 35
Required total daily payment = 35 × 9 = \$ 315

##### Correct Option: B

According to given bar graph in question ,
The daily payment made to each worker which contains 9 workers = \$ 35
Required total daily payment = 35 × 9 = \$ 315
Hence , The total daily payment made to the group which contains 9 workers is \$ 315 .

1. The number of workers whose daily payment to \$ 20 is

1. From the given bar graph in question , we see
The number of workers whose daily payment to \$ 20 is 20 .

##### Correct Option: C

From the given bar graph in question , we see
The number of workers whose daily payment to \$ 20 is 20 . Therefore , required answer is option C .
