As it is clear from the name, this is the second part of the Data Interpretation series. So, before continuing to this blog, read the first part i.e. <a href="https://www.thedhronas.com/blog/learn-the-basics-of-data-interpretation-for-bank-exams" target="_blank">Learn the basics of Data Interpretation for Bank Exams</a>. If you've already done reading, let's start with Tables then.

<h2 id="content-id-18997-0">Tables</h2>

The interpretation of data of the tables is done on the basis of the assessment of the numerical figures in the light of interrelated captions and the style of the table. In fact, more attention is focused on the relative position of different items in a table and answered mostly regarding it.

<h3>Based on Single Table:</h3>

E.g. The following table gives information about marks se- cured (out of 100) by three students in three subjects.

<table border="1" cellpadding="1" cellspacing="1" style="width:300px">
	<tbody>
		<tr>
			<td>
			Name
			</td>
			<td>
			Mathematics
			</td>
			<td>
			Science
			</td>
			<td>
			Social
			</td>
		</tr>
		<tr>
			<td>
			Rashmi
			</td>
			<td>
			65
			</td>
			<td>
			85
			</td>
			<td>
			50
			</td>
		</tr>
		<tr>
			<td>
			Reshma
			</td>
			<td>
			95
			</td>
			<td>
			75
			</td>
			<td>
			60
			</td>
		</tr>
		<tr>
			<td>
			Rajini
			</td>
			<td>
			75
			</td>
			<td>
			65
			</td>
			<td>
			55
			</td>
		</tr>
	</tbody>
</table>

 
(1) Who scored the highest marks in all the three subjects put together?

(2) The marks scored by Reshma in science is what percentage of the marks she scored in social?

Sol: (1) First we will find the sum of numbers obtained by everyone

Rashmi = 65 + 85 + 50 = 200

Reshma = 95 + 75 + 60 = 230

Rajini = 75 + 65 + 55 = 195

Reshma got the highest marks all the three subjects put together. (Ans.)

(2) Marks scored by Reshma in science is 75 and in social is 60.

⇒ (75/60) × 100% = 125% (Ans.)

Now, let's look at a question based on two or more tables.

<h3>Based on two or more Tables:</h3>

E.g. Refer to the following tables and answer the questions given below.

<table border="1" cellpadding="1" cellspacing="1" style="width:300px">
	<tbody>
		<tr>
			<td>
			Godowns
			</td>
			<td>
			Quantity available
			</td>
		</tr>
		<tr>
			<td>
			1
			</td>
			<td>
			150
			</td>
		</tr>
		<tr>
			<td>
			2
			</td>
			<td>
			220
			</td>
		</tr>
		<tr>
			<td>
			3
			</td>
			<td>
			190
			</td>
		</tr>
	</tbody>
</table>

 

<table border="1" cellpadding="1" cellspacing="1" style="width:300px">
	<tbody>
		<tr>
			<td>
			Outlets
			</td>
			<td>
			Quantity Required
			</td>
		</tr>
		<tr>
			<td>
			A
			</td>
			<td>
			220
			</td>
		</tr>
		<tr>
			<td>
			B
			</td>
			<td>
			140
			</td>
		</tr>
		<tr>
			<td>
			C
			</td>
			<td>
			180
			</td>
		</tr>
	</tbody>
</table>

 
Transportation cost per unit (in Rs.)

<table border="1" cellpadding="1" cellspacing="1" style="width:300px">
	<tbody>
		<tr>
			<td rowspan="2">
			Godowns
			</td>
			<td colspan="3">
			Outlets
			</td>
		</tr>
		<tr>
			<td>
			A
			</td>
			<td>
			B
			</td>
			<td>
			C
			</td>
		</tr>
		<tr>
			<td>
			1
			</td>
			<td>
			8
			</td>
			<td>
			6
			</td>
			<td>
			10
			</td>
		</tr>
		<tr>
			<td>
			2
			</td>
			<td>
			5
			</td>
			<td>
			3
			</td>
			<td>
			7
			</td>
		</tr>
		<tr>
			<td>
			3
			</td>
			<td>
			4
			</td>
			<td>
			9
			</td>
			<td>
			12
			</td>
		</tr>
	</tbody>
</table>

 
(1) If only godown 3 was available, then at what minimum cost can it supply all the quantity available?

(2) If only godown 2 was available, then at what minimum cost can it supply all quantities available?

(3) If only outlet A is present, then what will be the minimum cost of supply?

Sol: (1) As we have to minimize the cost we have to opt only for A and B

To outlet B = 140 × 3 = 420

To outlet A = 80 × 5 = 400

⇒ 420 + 400 = Rs 820 (Ans.)

(2) We have to minimize the cost, so we prefer godown 3 then 2.

From godown 3 = 190 × 4 = 760

From godown 2 = 30 × 5 = 150

Total cost of transportation = 750 + 150 = Rs 910 (Ans.)

(3) If only godown 3 is available, then we will opt for A.

⇒ 190 × 4 = Rs 760 (Ans.)

So, this type of questions on Tables are asked in Banking exams. Now, let's look at another type of Data Interpretation i.e. Caselets.

<h2 id="content-id-18997-1">Caselets</h2>

Questions on caselets are some easy but tricky real-life ques- tions that you have to solve by some common sense in addition to some quant tricks which you have learned already. These questions are based on the information given below.

<img loading="lazy" alt="Data Interpretation Caselets" src="https://www.thedhronas.com/admin/assets/uploads/ckeditor/Data Interpretation Caselets.jpg" style="height:200px; width:400px">

E.g. Mr. Alex is a private employee and earns a fixed salary every month. While filing his income tax returns in a financial year, the accountant noticed the following. Tax is always calculated on the income after deductions if any. The deductions are as follows.

(i) The standard deduction is one-third of the annual salary.

(ii) Mr. Alex donates Rs 40,000 to the PM’s National Relief Fund which gives 100% exemption. After allowing the deductions, the remaining income is taxed, which is the tax before rebate. The rate of tax on his taxable income is 20%. As he saves Rs 35,000 towards CPF (Contributory Provident Fund) and Rs 25,000 towards PPF (Public Provident Fund), and 20% of each can be deducted (rebate) from the tax calculated before rebate. This is the tax after rebate.

The surcharge is computed on the tax after rebate and the total amount to be paid is calculated. The surcharge is Rs 5,000 which is 5% of the tax after rebate.

Questions:

(1) What is the monthly salary of Mr. Alex (in Rs)?

(2) Had the standard deduction been one-sixth of the annual salary, all other things remaining the same, then what would have been his monthly salary?

Sol: (1) After reading this question in the exam scenario I will suggest to you if you are not from such a background or not comfortable with similar questions you should not attempt this. 
I am not from such a background so I will make it simple and realistic.

Our first question is about monthly salary so let the annual salary of Mr. Alex be ‘x’

Taxable income = (x – x/3 – 40000) = (2x/3 – 40000) {by (i)}

Now, tax = 20% of (2x/3 – 40000) = (2x/15 – 8000)

As he saves Rs 60,000

rebate = 20% of 60,000 = Rs 12,000

Tax after rebate = (2x/15 – 8000 – 12000) = (2x/15 – 20000)

Surcharge = 5% of (2x/15 – 20000) = Rs 5,000

⇒ x = Rs 9,00,000

Monthly salary = 9,00,000/12 = Rs 75,000 (Ans.)

(2) We just simply follow what is written.

Taxable income = (x - x/6 - 40000) = (5x/6 - 40000) Now, tax = 20% of (5x/6 - 40000) = (x/6 - 8000)

Tax after rebate = x/6 - 8000 - 12000 = x/6 - 20000 Surcharge = 5% of (x/6 - 20000) = 5000

So, x = 720000

Monthly Salary = 720000/12 = 60000 (Ans.)

This is one of the classical examples in the caselet question, it can be unsolvable for many at first go but now as you all are familiar with it, we hope you will tick all the questions right in the examination.

E.g. In a fast-food shop, there are 1800 visitors in a month, they orders five different snacks namely Burger, Pizza, Fries, Hot dog, and Cake. Out of the female visitors, 24% order burgers, 28% order pizza, 12% order fries, 15% ordered cakes, and the remaining 147 order hotdogs. Out of the total male visitors 14% order burger, 26% order pizza, 28% order fries, 18% order cake, and the remaining 154 order hotdog.

(1) What is the ratio of the number of male visitors ordering Pizza to the number of female visitors ordering Burger?

(2) What is the average number of females ordering Fries, Hot dog and Cake?

Sol: (1) Number of female visitors ordering Burger = 24% Number of female visitors ordering Pizza = 28%

Number of female visitors ordering Fries = 12% Number of female visitors ordering Cakes = 15%

Number of female visitors ordering Hot dog = 100 - (24 + 28 + 12 + 15) = 100 – 79 = 21%

= 21% is equivalent to 147

Total number of female visitors = 700

Total number of male visitors = 1800 – 700 = 1100

Number of male visitors ordering Burger = 14%

Number of male visitors ordering Pizza = 26%

Number of male visitors ordering Fries = 28%

Number of male visitors ordering Cakes = 18%

Number of male visitors ordering Hot dog = 100 – (14 + 26 + 28 + 18) = 100 – 86 = 14%

= 14% is equivalent to 154 (Ans.)

(2) Total number of male visitors ordering Pizza = 26% of 1100 = 0.26 × 1100 = 286

Total number of female visitors ordering Burger = 24% of 700 = 0.24 × 700 = 168

Required ratio = 286 : 168 = 143 : 84 (Ans.)
