We all know how important Data Interpretation Questions are in IBPS PO Exam  . The weightage of marks on Different Types of Data Interpretation Questions varies from 10-45. One of the most important question that is asked from Different types of Data Interpretation is on Interpreting the Tabular Form. This post will help you solve different types of questions that are asked from tabular form of Data Interpretation

In our previous post
 Data Interpretation I: Data Interpretation Tricks to SolveData Interpretation Questions, we discussed the meaning and definition of Data Interpretation and few tricks to solve Data Interpretation question. 
In this post, we will discuss little tips and tricks to solve questions on Tabular form of Data Interpretation.

Model 1: Tabular Form

Tabular form or Tables is an easy area to score marks in the aptitude section of IBPS, SBI PO and SSC exams. One or two problems in the exam are asked on Tabular form of Data Interpretation.

A tabular form is a representation of data in a table format. It is easy and convenient to represent data in a tabular form. The data is present in rows and columns and one can draw conclusions from it easily. It is the most organized method to represent data.

Let us now look at the different types of Data Interpretation questions that are asked from the tabular form.
Tabular Form
Problem I: Total 24500 people who are in the given profession and (of these) percentage of female and males.
Tabular Form
Question 1: What is the ratio of the total number of males in the medical and teaching profession together to the ratio of females in the same professions together?

*Tip: Ratio is the comparison of like terms in its simplest form.

Solution:
Step 1:
As we need to find the ratios, we use the formula
Males ( Medical + Teaching): Female ( Medical + Teaching)

Step 2: 
By substituting the values in the above formula
(40% x 11%x 24500)+(20% x 21% x 24500) : (60% x 11% x 24500)+(80% x 21% x 24500)

Step 3: 
By eliminating 24500 and percentage as it is common, according to the concept of ratio we get,
(40 x 11) + (20 x 21) : (60 x 11) + (80 x 21)

Step 4: 
By Simplification,
22 + 21 : 33 + 84
= 43 : 117 

Therefore, The ratio of total number of Males: Females in the medical and teaching profession together is 43:117

*Note: Don't write the steps during examination as it consumes a lot of time. Directly jump to the step 3 as 24,500 is common and step 2 can directly be eliminated.

Question 2: Total number of people in the teaching profession is what percent of total number of people in law?

*Tip-In this question we are suppose to find the percentage change

Solution:
Step 1: 
As we need to find the percentage change, we need to use percentage formula
x is what of % of y  = (x/y)100 [Formula]
X-Total number of people in teaching program
Y- Total number of people in law

Step 2: 
By substitution,
(Total number of people in teaching program/ total number of people in law) x100

Step 3: 
By substituting values in the above formula,
(21% x 24500/24% of 24500) x 100

Step 4: 
By simplification,
21/24 x 100

Step 5: 
By simplification,
7/8 x 100
= 87.5%

Therefore, the total percentage of people in the teaching profession is 87.5% of the total percentage of total people in law.

Question 3: What is the total number of males from all the profession together? 
1) 11472  2)12784  3)12348  4)12453  5) None of these

Solution:
Step 1: 
As we need to find the total number of males in all the profession, we are suppose to take (the percentage of males in one profession x percentage of the total number of people in that profession x total number of people) and thus we need to add all the values together.

(40% of 11% of 24500)+(70% of 18%of 24500)+(55% of 24% of 24500)+(20% of 21% of 24500)+ (65% of 16% of 24500)+(56% of 10% of 24500)

Step 2: 
By Simplification,
(40 x 11) + (70 x 18) + (55 x 24) + (20 x 21) + (65 x 16) + (56 x 10)
= 5040

Therefore the answer is Option 5 - None of these.

In examination on average about 30 to 36 seconds are allotted to solve a question. Though this question appears to be simple the process of calculation is really lengthy as we cannot eliminate any number. The quickest way to solve this question is to skip the question or else leave the question for the end.

Question 4: The female in the Engineering professions are what percent of males in the management profession.
1) 71.71  2) 96.43 3) 83.16 4)68.54 5) None of these

Solution:
Step 1: 
As we need to find the percentage change, we use the percentage formula,
x is what percent of y = x/y x 100
x- Females of Engineering
y-Males of Management

Step 2
By using the percentage formula in finding out the female engineering profession percentage to male percentage in management profession
Females of Engineering/Males of Management x 100

Step 3: 
By substituting the values in the formulas,
30% of 18% of 24500/56 x 10 x 24500

Step 4:
By simplification,
30 x 18 /56 x 10 x 100

Step 5
By simplification
54/56 X 100
= 96.43%

Therefore, the answer is option 2 - 96.3%.

Remember don't waste your time in writing down steps. Directly jump to step 4 and eliminate all unnecessary steps.Solve this sum on the bases of assumption, it will help you to save some time.

Question 5: What is the ratio of number of males in the banking profession to the number of males in the engineering profession.

Solution:
Step 1: 
We use the formula as we need to find the ratio of males in banking to ratio of males in Engineering
Males (Banking) : Males ( Engineering)

Step 2: 
By substituting the values in the formulas,
65% x 16% of 24500 : 70% x 18% of 24500

Step 3: 
By simplification,
65 x 16 : 70 x 18

Step 4: 
By Simplification,
52 : 63

Therefore, the ratio of number of males in the banking profession to the number of males in engineering profession is 52:63.
