## Bar Graph

A bar graph is nothing but a pictorial representation of data wherein every independent variable attains only discrete value. They are used for representing various types of data.

The bar graph is one of the frequent methods used to present various types of data. It is usually asked in the data interpretation section of the competitive exams. In data interpretation, it is the representation of data where the vertical bars are placed at equal distance from each other. The value of the data represented is given by the height and length of the bars. The width here is not important it is only used so that the presentation is clear.

They are plotted against the horizontal axis known as the x-axis. The value can be shown by coloured or shaded vertical bars of equal width. In a horizontal bar graph, the values are plotted against the vertical axis called the y-axis. They are commonly used as the data can be easily analyzed.

## Types

There are types of bar graphs used to represent the data. They are as follows.

1. Simple bar graph

2. Composite bar graph

3. Stacked bar chart

4. Bar charts to show deviation

### Simple Bar Chart

As the name suggests simple bar chart is the simplest bar graph of all. It is used to describe one continuous variable along with the one discrete value. The figure below shows the proper representation of a simple bar chart.

### Composite Bar Chart

To solve the limitation of simple bar chart composite bar chart is used. We use a composite bar chart to show two or more than two continuous variables on the same graph. This is the figure below that describes how a composite bar-chart looks like.

### Stacked Bar Chart

Stacked bar charts are used to represent the break-up of the content for continuous variables. It is very convenient to use it for comparing different sets of data. It can be used to represent factors such as revenues, profits, losses over a period of couple years. The figure below describes the same.

### Bar Charts to Show Deviation

Mostly bar charts are used to show the deviation. And that is why the bar charts that are used to show the deviation are very common. Deviation charts can show the deficit as well as the surplus, imports, and exports, etc. It is usually required to represent the positive as well as negative values of the continuous variables.

As shown in the figure a baseline is created wherein the positive values are shown above the line while the negative values are shown below the line. Answer the questions based on the given figure below.

Q. Out of the given years, in how many did the export was more than 10% as compared to the import?

A. 1 B. 2

C. 3 D. 4

Answer: In the year 2000, exports were 60 while the imports were 50. So 10% of 50 is 5. And thus the total will be 55. Here 60 > 55. Similarly in 2001, 110 = 10% of 100.

In 2002, 120 < 130. For 2003, 120 > 10% of 100. For 2004, 150 < 10 % of 140.

In 2005, 190 < 10 % of 180. So there are years i.e. 2000 and 2003 where exports were 10 % greater than the imports. So the correct answer is B.

Q. For all the years mentioned what is the average of the exports?

A. 110 B. 120

C. 125 D. 130

Answer: Here from the figure the average of the exports will be: (60 + 110 + 120 + 120 + 150 + 190)/ 6 = 125. So the correct answer is C.

Q. From the numbers given in the figure below, what will be the average annual growth for the imports done from 2001 to 2005?

A. 11 B. 12.5

C. 13.5 D. 14.5

Answer: Imports done in 2001 = 110

Imports done in 2005 = 190

So, the annual growth = (190 – 110)/110 * 100 = 72.72%

Now, the average growth will be 72.72/ 5 = 14.5. So the correct answer is D.

Q. From 2000 to 2005 in which was the growth in imports as compared to the previous years was the highest?

A. 2001 B. 2002

C. 2004 D. 2005

Answer: From the figure, we can determine that imports grew only in 2001, 2002, 2004, and 2005.

For 2001, (50 * 100) / 60 = 83.33

For 2002, (10 * 100) / 110 = 9.09

For 2004, (30 * 100) / 120 = 25

For 2005, (40 * 100) / 150 = 26.66

Thus the correct answer is A. This type of questions can be solved quickly if you compare the base for every year. Here for 2001, the base value is 60 and thus chances are high the growth in 2002 must have been higher. You can look for this in the exams and start by solving 2002. This will save a lot of your time.

Q. In how many years does the export as well as import increases as compared to the previous years. And among them, in how many years was the percentage increase in export was greater than the percentage increase in imports

A. 0 B. 1

C. 2 D. 4

Answer: Out of all the years given in the figure, the imports and exports as compared to the previous are increased in every year except 2000 and 2003. Out of the four in which imports and exports have increased, in no year does the percentage increase in export is greater than the percentage increase in imports. Thus the correct answer is A.

## Line Chart

The line chart is nothing but an upgraded version of a bar chart. It is formed by connecting the uppermost point of the bars so that we have a line. By repeating this following process, with other bars as well we will get a line chart. The calculations can be tough but the main aim of the examiner is to check whether you can apply logic to eliminate options and evaluate the graph thereby getting the answer.

On the basis of the figure below answer the following question. In the graph, the number of boys and girls are given in five schools. Study this graph properly and answer the questions.

Q. What percentage will be the number of girls in school A out of the total number of girls in all the schools?

A. 15 B. 17

C. 22 D. 24

To solve this question there are several different approaches. Let’s look into each approach one by one.

### First method

For the first method, we can calculate the number of girls simply by adding all the girls in the schools and then taking the girls from school A as the numerator thereby calculating the total percentage of girls. For example, in this question, the total number of girls is 17750 and the girls in school A as a part of all the girls in all the schools will be (2750/17750) x 100 = 15.4%

The major roadblock in this method is that it requires a lot of calculation and there are chances that you may calculate in exam properly which might lead to silly mistakes. And that is why we have given a second approach to this question.

### Second method

This method is based on the estimation. In this method, you have to suppose a baseline and then from the given options, you have to assume which is the closest to the answer. Suppose, there are 5 schools and every school has an equal number of 10 girls so the average will 10 and the percentage will 20%. Same will be the case for 100 girls with 5 schools. Here the percentage will be dependent on the number of schools.

In the above question also assume a baseline at the centre of the figure. As there are five schools given in the question the percentage will be 20% but the base-line is above the number of girls in A. So we can say that the number of girls in school A will be less than 20%. Thus options 3 and 4 can be negated. Now for the remaining options when we look at E and compare it with A, there is the larger difference and so 17% cannot be answered as well. Thus the remaining option is 15 which is the correct answer.

This method should only be done when the options are not very close. Thus the correct answer is (1).

#### Q. Which class has the percentage of boys and girls as part of the total students in all the schools?

A. A B. B

C. C D. D

From the figure you can see the highest of boys and girls in one school is in D. As the base for all the schools remains a same i.e. total number of students all the schools will be same for every school then we can say that in school the percentage of students is the highest. Thus the correct option is (3).

#### Q. Which school has the lowest number of students?

A. A B. B

C. C D. D

In school C the number of students is the lowest. Thus the correct option is (3).

## Practice Questions

## Tabular Form

One of the simplest methods used to analyze the data and to display the data is in tabular form. In the tabular form, you get a systematic arrangement of rows and columns. The first column is used to indicate the titles and the first row is also used to indicate the same. It is very accurate as well as an easy method to display the data. Although this is a simple method, it can be time-consuming as well. To solve this section easily we will provide you with some tips and tricks.

## Tips to solve tabular form questions

- This technique can be very time-saving and can be particularly helpful when the options are not very close. In this technique, you have to calculate everything by rounding it up to ‘0’ as the last digit.
- While looking at the data, be sure that you are in the right column and row. Try and check the information as carefully as you can.
- While carefully going through the data be absolutely sure about the units that are used. This will be helpful when there are conversions asked. A single ‘0’ can make your answer wrong.
- Before solving the question have a look at the options as well. If they are not very close then try and solve as quickly as you can.
- While looking at the options do note whether they are in percentage or decimal. This will help you when you start solving the question. And in the end, if you are required to convert your answer as well.

### Sample Question

The table below shows the number of the mobile phones that were sold by the showroom in the years from 2006 to 2010. Answer the below questions based on the information given in the table.

Years / Showroom | A | B | C | D | E | F |

2006 | 183 | 123 | 277 | 167 | 178 | 237 |

2007 | 178 | 272 | 269 | 95 | 379 | 198 |

2008 | 133 | 161 | 226 | 176 | 239 | 277 |

2009 | 264 | 107 | 237 | 225 | 282 | 237 |

2010 | 278 | 272 | 213 | 284 | 293 | 196 |

Q. How many percentages of mobile phones were sold by the showroom E in 2008 less than the showroom A in 2010?

A. 10 B. 12

C. 14 D. 16

The total number of mobile phones there were sold by E in 2008 = 239.

The total number of mobile phones there were sold by P in 2010 = 278.

So, the reduction in percentage will be ((278 – 239)/278) * 100 = 14.02 %

As the values in the question are rounded off to nearest integer the correct answer 14%. So the correct option is B.

Q. What will be an average number of mobile phones sold by all the showrooms in the year 2007?

A. 215 B. 222

C. 208 D. 213

We know the formula for the average which is total mobiles sold in 2007/number of stores.

Here total number of mobile phones = (178 + 272 + 269 + 98 + 379 + 198) = 1294

Number of mobile showrooms are 6.

So, 1294/6 = 215.66.

So the correct answer is 215.

## Caselet Form

There are a lot of things that you need to keep in mind while solving data interpretation. It is important that you understand the data given and how the data is linked. Before solving the question see what you can derive from the information given to you. Caselet form is one such type where you need to comprehend with lots of data. The question given to you will be in the paragraph form rather than some table or chart. Thus it becomes important that you remember the data well. Here are a few caselet form questions for your understanding.

### Examples

Q. Mr. Shyam wants to buy a watch which is priced at Rs. 40,500. The watch is also available at Rs. 20,000 down payment and the monthly installments of Rs. 1400 per month for 2 years or Rs. 16,000 down payment and a monthly installment of Rs. 1100 per month for 3 years. Mr. Shyam has with him Rs. 10,000 only. He wants to borrow the balance money of the down payment from a private firm. The terms of that private firm are:

If Rs. 5000 is borrowed for a period of 12 months, the rate of interest is 20 %. The interest will be calculated on the whole amount for the whole year itself. Thus the borrower needs to pay an amount of Rs. 500 per month for 12 months, because 5000 is the principal amount + 1000 as the interest rate.

If more than Rs. 9,000 is borrowed for 1 year, the rate of interest is 25 % and is calculated in exactly way as given above.

### Case 1:

1. Suppose that Mr. Shyam is ready to pay either of the down payments then which of the installments schemes is the better option of the two? (Assume that Mr. Shyam will pay the installments out of his own pocket and he keeps his savings with himself and earns no interest on the same. Also assume that instead of borrowing the remaining money for the down payment, he saves the balance before the purchase.

A. 1100 for 3 years B. 1400 for 2 years

C. Either A or B D. Data insufficient

Ans: We need to compare the two downpayments given to us in the question and find out which one is better. One of the downpayment is available at 1400 for 2 years and other is given at 1100 for 3 years.

The total cost of the 1st downpayment will be: 20000 + 16800 + 16800 = Rs. 53600

The total cost of the 2nd downpayment will be: 16000 + 13200 + 13200 + 13200 = Rs. 55600

Thus the 1st downpayment will be a better option for Mr. Shyam as there is no interest claimed by Mr. Shyam. So, the correct answer is B.

### Case 2:

2. What is the percentage difference in the total amount paid to the watch dealer, between the two installment schemes (with respect to the total payment of the scheme with Rs. 20,000 as the down payment)?

A. 3.73 % B. 3.37 %

C. 3.33 % D. 3.53 %

Ans: Here, we need to find the actual difference in percentage between the two installments given. The total cost of the 1st down payment is 20000 + 16800 + 16800 = Rs. 53600 and the total cost of the 2nd installment is 16000 + 13200 + 13200 + 13200 = Rs. 55600. Thus, the difference between the two installments is 55,600 – 53,600 = Rs. 2000. So the difference in percentage is 2000 x 100/53600 => 3.73 %. So, the correct answer is A.

### Case 3 :

3. If Shyam can spare an extra of Rs. 2500 which is to be paid to the watch dealer and the money lender from his monthly earnings start from the first month itself, which scheme would Shyam choose?

A. 1200 for 2 years

B. 1400 for 2 years

C. 1100 for 3 years

D. Data insufficient

Ans: From the data given in the question, the amount that has to be taken for the second installment is Rs. 5000. So, the monthly expenses of Shyam will be Rs. 500 per month + the monthly installment of Rs. 1100 per month to the money lender. Thus, the total repayment will be of Rs. 1600. If Shyam opts for the first installment than he needs to borrow Rs. 10,000. Because of this Shyam has to pay a monthly installment of Rs. 1041.66 to the money lender. This is because for the amount more than 9000, 25 % tax is charged to the amount will 10000 + 2500 for 12 months. In addition to this, Shyam also needs to pay an extra amount of Rs. 1100 to the money lender. So, the total amount will Rs. 2141.66 per month.

The above amount is inside his limit so he will go with the above scheme. Thus, the correct answer is C.

You can analyze this data to solve the questions given. The radar-based structure is also known as the spider based structure.

### Examples

**Directions**

In the question below, the sales of TV and laptop in the subsequent years from 2004 to 2009 is given. The figures given to you is in million. Based on the figure answer the questions below.

1. How many times do the sales of a laptop less than the TV in the given years?

A. One B. Two C. Three D. Four

Ans: Here the sales of televisions and laptops of six different years are given. You need to see that in which year the sale of TV was greater than the sale of the laptop. The values of different sales of units are given to you in the radar diagram above.

From the figure you can see that sales of the laptops in 2004 were lower than the sales TVs in 2004, similarly, sales of a laptop in 2005, 2008, and 2009 was lower than the sale of TVs in that year. So, there are four years where the sale of the laptop was lower than the sale of TV. Thus, the correct answer is D.

2. Find the ratio of the total number of televisions sold to the total number of laptops sold in all these years.

A. 4: 5 B. 5: 6 C. 5: 4 D. 6: 5

Ans: Here, you only have to add the total number of televisions laptop sold in all these years and compare them to find the ratio. The total number of televisions sold from 2004 to 2009 are 25 + 22.5 + 22.5 + 25 + 25 + 30 = 150. And the total number of laptops sold are: 20 + 15 + 25 .5 + 30 + 20 + 10 = 120.5. Thus the ratio of the is 150: 120.5 = 5: 4. So, the correct answer is C.

3. Which item and for which year shows the highest percentage increase in the sales in the previous year?

A. Laptop 2007 B. TV 2007

C. Laptop 2006 D. TV 2009

Ans: In this question, we need to find the increase in the percentage of the given items in comparison to previous years. Instead of checking all the years, we will only check percentage increase for the one given in the option. For laptop 2007, in the previous year, the sales were 30 million while in 2006 it was 25.5 so there is an increase of 4.5 million units. Therefore percentage increase will be 4.5/25.5 x 100 = 18%.

Similarly for TV 2007 it will be, 2.5/22.5 x 100 = 11.11 %. For Laptop 2006 it will be, 7.5/15 x 100 = 50 % and for TV 2009, it will be 5/25 x 100 = 20 %. So for laptop 2006, the percentage increase in sales is the highest. Thus, the correct answer is C.

4. For the data series shown in the above figure, how many years have shown the decrease in sales for both the items in the same year?

A. One B. Two C. Three D. Four

Ans: We need to find the decrease in sales for both the items given and that too during the same year. This only happens one time in the year 2001 where sales of TV decreases from 20 million to 10 million and sales of laptop decreases from 25 million to 22.5 million. So, the correct answer is A.

5. Which year shows the highest percentage decrease in the total sales of the two items?

A. 2005 B. 2006 C. 2008 D. 2009

Ans: We need to first calculate the total sales of both the items in each of the years given above. The total sales will be:

Year | Total sales |

2004 | 45 |

2005 | 37.5 |

2006 | 48 |

2007 | 55 |

2008 | 45 |

2009 | 40 |

Now, from the table, you can see the decrease in sales occurs only thrice during 2005, 2008, and 2009. So we will calculate percentage decrease for only these three years. For 2005 decrease in sales are 7.5 million. So, the percentage decrease from the previous year will be 7.5/45 x 100 = 16.6 %. Sales decreased by 10 million from 2007 to 2008. Thus, the percentage decrease will be 10/55 x 100 = 18.18 %. For 2009 the decrease is 5 million and so the percentage decrease will be, 5/45 x 100 = 11.11 %. So, the highest percentage decrease was noted in 2008 from 2007. So, the correct answer is C.

## Pie Charts

In pie charts, the entire diagram looks like a pie and the components in it resembles the various slices cut from the pie. The pie-chart is thus used to show the break-up of one continuous variable into its components parts.

Source: Pixabay

For, the example you can see the distribution of sales of the laptop industry between five companies:

Company | % in market share |

HP | 22 |

Dell | 33 |

Lenovo | 13 |

Asus | 15 |

Acer | 17 |

The pie chart represented above shows a circle of 360 degrees which represents 100 % of the values of the continuous variable. Thus, 3.6 degree of the pie chart represents 1 % of the total values of the variables being represented. Pie-charts are more versatile than the bar graphs, tables or two variables graphs. It also represents the clear and precise data that needs to display. Thus, also helps you establish the relationship between different sectors.

1. If the value of the market share of BOI is Rs. 4000 crores, then the market share of BOB and Axis bank together is:

A. 24,363 crores

B. 24,432 crores

C. 24,864 crores

D. 25, 827 crores

This is the most common question asked in the pie chart section. You will be given the share price and based on its comparison with the percentage given in the question you need to determine the answer. Thus, in this question, you can see that BOI accounts for 11 % of the market share. And this 11 % is equal to the 4000 crores. So to calculate the total market share of BOB and axis the formula will be, 67/11 x 4000 = 24,363. Thus, the correct answer is A.

2. If the total market share other than Axis and BOB is Rs. 335,000 crores. Then find the market share of BOI and HDFC banks.

A. 274,560 crores

B. 274,090 crores

C. 274,809 crores

D. Cannot be determined

Here, from the pie-chart, you can determine that the total market share of Axis and BOB in terms of percentage is 67 % and this is equal to Rs. 335,000. In addition to this the other banks that are left accounts for 33 % which equates to 35,000 crores. HDFC and BOI equal the market share of 27 %. Thus, their market share in terms of crores is 27 x 335000/33 => 274090 crores. So, the correct answer is C.

3. Find the approximate ratio of market share between BOI and BOB.

A. 1: 2

B. 3: 1

C. 1 : 3

D. Not possible

Take the market share of BOB and BOI and compare them both to find the ratio. As a result, the market share of BOB is given as 34 % and the market share of BOI is given as 11 %. So, the ratio of market share of BOI to a market share of BOB will be 11: 34. This will be close to 1 : 3. So, the correct answer is C.

A. 45 %

B. 50 %

C. 55 %

D. 62 %

We need to determine the market share Axis bank for next year. For the current year, the share of Axis bank is 33 %. So now we need to determine the next year share of Axis bank. It is given that this share of Axis bank will be doubled while the shares of the other banks are constant. So the total percentage of all the shares will be 133 because Axis bank will 66 % of the market share. 66 is 50 % of 133, so the market share of Axis bank in the next year will be 50 %. Thus, the correct answer is B.
