Tabular DI Tricks & Tips
Data Interpretation questions typically have large amounts of data given in the form of tables, piecharts, line graphs or some nonconventional data representation format. The questions are calculation heavy and typically test your approximation abilities. A very large number of these questions check your ability to compare or calculate fractions and percentages. If you sit down to actually calculate the answer, you would end up spending more time than required. Here are few ideas that you can use for approximation.

Funda 1 Calculating (Approximating) Fractions
When trying to calculate (approximate) a fraction p/q, add a value to the denominator and a corresponding value to the numerator before calculating (approximating).
Example,
What is the value of 1789/762 ?
First the denominator. We can either take it close to 750 or to 800. Lets see how it works in both cases. We know that the answer is between 2 and 3, so for adding values / subtracting values from the denominator or the numerator, I will consider a factor of 2.5.
Case 1: 762 is 12 above 750, so I will subtract 12 from the denominator. Keeping the factor of 2.5 in mind, I will subtract 25 from the numerator.
My new fraction is,
(1789 – 25) / (762 – 12) = 1763 / 750 = 1763 ? (4 / 3000 ) = 7.052 / 3 = 2.350666
Actual answer is 2.34776.
As you can see, with very little effort involved in approximation, we arrived really close to the actual answer.
Case 2: 762 is 38 below 800, so I will add 38 to the denominator. Keeping the factor of 2.5 in mind, I will add 95 to the numerator.
My new fraction is,
(1789 + 95) / (762 + 3 = 1884 / 800 = 2.355
As you can see, even this is close to the actual answer. The previous one was closer because the magnitude of approximation done in the previous case was lesser.
Funda 2 Comparing Fractions
If you add the same number to the numerator and denominator of a proper fraction, the value of the proper fraction increases.
If you add the same number to the numerator and denominator of an improper fraction, the value of the improper fraction decreases.
Note: You can remember this by keeping in mind that,
1/2
and
3/2 > 4/3 > 5/4 > 6/5 …
Example,
Arrange the following in increasing order: 117/229, 128/239, 223/449.
Lets first compare 117/229 & 128/239.
If we added 11 to the numerator and the denominator of the first proper fraction, the resulting proper fraction would be 128/240, which will be bigger in value than the original (as per Funda 2).
We know that 128/240 is smaller than 128/239, as the latter has a lower base.
So, 117/229
? 117/229
Now lets compare 117/229 and 223/449.
If we added 11 to the numerator and the denominator of the second proper fraction, the resulting proper fraction would be 234/460, which will be bigger in value than the original.
If we doubled the numerator and denominator of the first proper fraction, the resulting proper fraction would be 234/458.
We know that 234/460 is smaller than 234/458, as the latter has a lower base.
So, 223/449
? 223/449
Using the above two results, we can say that 223/449
Note: This question can be solved much simply by just looking at the numbers and approximately comparing them with 12. I used this long explanation to illustrate the funda given above.
Following are a few other shortcuts that might come in handy during DIrelated calculations.
Funda 3 Percentage Growth
If the percentage growth rate is r for a period of t years, the overall growth rate is approximately: rt + t * (t1) * r2 / 2
Note: Derived from the Binomial theorem, this approximation technique works best when the value of ‘r’ is small. If the rate is above 10%, then this approximation technique yields bad results. Also, if the rate is 5% then r = 0.05; if the rate is 7.2% then r = 0.072.
Funda 4 Comparing Powers
Given two natural numbers a and b such that a > b > 1,
ab will always be less than ba
Note: There are only two exceptions to this funda. I hope someone in the comments will point them out (anyone?).
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.
Problem I: Total 24500 people who are in the given profession and (of these) percentage of female and males.
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?
*TipIn 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]
XTotal 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
yMales 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.
Tables refer to the arrangement of data in the form of rows and columns.
Positives  Negatives 

1. Data is available in a compiled form; hence there is no ambiguity in interpretation.  1. Trends cannot be easily established in the table. 
2. Data Values are directly given and hence one need not spend time finding the accurate Values.  2. One can get confused over the sheer volume of the data. 
Shortcuts to crack DI sets containing Tables
1. Do not get carried away by the sheer amount of data, the set may be easy for all you know!!
Check out this table from CAT 2002.
At the first glance, it seems that this table has too data intensive and hence should not be attempted. But on second thoughts if you look at the questions, you will find that this is a simple set pertaining to counting some values. So rather than getting carried away by the volume of data, you need to have a look at the questions as well.
2. Modify the question such that the answers can be easily calculated.
Check out this table pertaining to CAT 2005.
In the first question, we need to find the ratio of ‘production to population’ i.e. divide the secondlast column with the last one and find out how many of these values are greater than that of Gujarat. However one may find that this division results in values in fractions and hence difficult to compute. Instead, if we were to modify the question and calculate the ratio of ‘population to production’ and find out how many of these values are less than that of Gujarat, the entire calculation becomes oral. For example, for Gujarat this value is between 2 and 3. We can find that the only states for which this value is less than that of Gujarat are Haryana (1…), Punjab (1), Maharashtra (2…) and Andhra Pradesh (0…).
Similarly in the second question, we need to simply figure out that the values of the second last column need to be multiplied by 10 and this needs to be divided by the values of the last column. The states where this value is more than 4 is Haryana, Gujarat, Punjab, Madhya Pradesh, Tamil Nadu, Maharashtra, Uttar Pradesh and Andhra Pradesh.

Tabular Representation
 The ratio of a to b is written as a : b = a / b
 The idea of proportions is that two ratio are equal. If a : b = c : d, we write a : b : : c : d
Tips on Solving Table Chart Problems:
A: Read the data very carefully, as the smallest detail may change the meaning of the question completely. Similarly, the instructions have to
be understood carefully to prevent wasting time in calculating data that is not required, and also to find out exactly what is the answer that
is sought.
B: Try to understand the data provided carefully, before jumping to answer the questions. The questions are designed to be deceptive, and proper understanding of the requirements is a must. If the Data provided is of the combined variety or if there are more than one data table/charts/graphs, try to understand the relation between the given tables.
For Example, one table may talk about absolute sales figures, while the other table may talk of sales as a percentage of production. Hence, any question on excess production or Goods in stock, will require data from both tables.
C: Be very careful of the units used in the tables, and the units in which the answers (options) are provided. A mistake in the units may yield an
entirely different answer. Also be careful of whether the answer is required in decimal or percentage. Such errors are common and easily
avoidable.
Here is an example consisting tabular data:
Example 1:
Category of Assistance

62.6

Example 1.1:
The category receiving the least percentage help from the centre (in the entire data) is:
(A) Category B in 1995 (B) Category C in 1996 (C) Category B in 1996 (D)Category D in 1995
Solution:
In this type of question, it is better to examine the alternatives given rather than trying to ﬁnd the least percentage from the table. Let us now calculate the required percentage of the given alternatives:
(A) Category B in I995 =(2.65.0)×100=52% (Even without calculation, you can eliminate this choice.)
(B) Category C in 1996 was =(10.059.4)×100=16.8%
(C) Category B in 1996 was =(1.63.2)×100=50% (Even without calculation, you can eliminate this choice.)
(D) Category D in 1995 =(55.0216.6)×100=25.4%
From this we arrive at the answer (B) since this is the least percentage.
Example 1.2:
The difference between the average costs paid by the Centre during 1995 and 1996 is
(A) Rs. 66 lakh (B) Rs. 13.2 crore (C) Rs. 132 lalth (D) Rs. 13.2 lakh
Solution:
Adding all the cost ﬁgures in the 1995 column, i.e. 18.4+2.6+13.0+6.6+55.0, you get 95.6.
The average in 1995: =95.6+ Number of categories =95.6+5 = Rs. 19.12 Crore
Similarly, the average in 1996: =(17.4+1.6+10.0+10.6+62.6)5 = Rs. 20.44 Crore
The difference = Rs. (20.44−19.12) Cr = Rs. 1.32 Cr = Rs. 132 lakh
The correct answer is (C).
(Note how the answer needed conversion from crores to lakhs).
Example 1.3:
Monthly cost to the city receiving E category assistance in 1996 is most nearly:
(A) Rs. 1.8 crore less than that in 1995 (B) Rs. 2.1 crore more than that in 1995 (C) Rs. 2.1 cnore less than that in 1995 (D) Rs. 1.8 crore more than that in 1995
Solution:
Here, straight calculation is only needed. We need to look at the total assistance ﬁgures.
In 1995: 216.612=18.05
In 1996: 242.812=20.23
Difference = 2.183 crore ≈ Rs. 2.1 crore
The correct answer is (B).
Example 1.4:
Assuming
that 50% of the persons receiving category B help in 1995 were adults
caring for minor children, but the city’s contribution towards
maintaining these adults was 40% of the total contribution to B program
in 1995, average amount paid by the city for each adult per year in 1995
is most nearly:
(A) Rs. 5900 (B) Rs. 6000 (C) Rs. 7500 (D) Rs. 3000.
Solution:
50% of persons receiving B category help during 1995 =3316
City’s contribution to maintenance: =5.0×0.4
= Rs. 2 crore =2,00,00,0003316
= Rs. 6031.36
= Rs. 6000 nearly
The correct choice is (B).
Example 1.5:
Monthly costs to the city of category D during 1995 and 1996 bear a ratio (most nearly)
(A) 2 : 3 (B) 5 : 3 (C) 3 : 2 (D) 3 : 5
Solution:
Again, we can straightaway determine the answer through simple calculation.
Since a ratio is required to be calculated, we can avoid the division by 12.
Directly from the table we have, total assistance in 1995 and 1996 for Category D as 26.4 and 42.6.
Hence the ratio is 26.4:42.6=3:5 nearly.
Sample Question
Direction: Refer to the following table and answer the given questions.
Number of cars sold by 6 Stores in 5 different months
The above Table shows:
 The number of cars sold by store P (In Jan = 133, Feb = 183, March = 278, April = 178, May = 264)
Like this we can see the others. Lets do solve some questions.
1. Number of cars sold by store T in march is what percent less then number of cars sold by Store P in may? (Rounded off to nearest integer)
(a) 29%
(b) 31%
(c) 37%
(d) 33%
Solution:
Number of cars sold by Store T in March = 178
Number of cars sold by store P in May = 264
Required percentage = (264 – 178 /264) * 100 (in question asked less then number that’s why we deducted) = (86/264) * 100 = 32.57%
So rounded figure it will be 33%, Answer D
2. What is the average number of cars sold by all the given stores in Feb?
(a) 207
(b) 211
(c) 219
(d) 223
Solution:
To find average we have to add all the figures of Feb month and then divided by 6
= 183 + 123 + 277 + 176 + 239 + 268 / 6 = 1266/6 = 211, Answer B
3. Total number of cars sold by store Q during all the given months together is what percent of the total number of cars sold by store S during all the given month together?
(a) 82%
(b) 88%
(c)92%
(d) 86%
Solution:
Total number of cars sold by store Q during all the given months together = 161 + 123 + 154 + 272 + 107 = 817
Total number of cars sold by store S during all the given months together = 225 + 176 + 98 + 284 + 167 = 950
Required percentage = (817/950) * 100= 86%, Answer D
4. What is the difference between total number of cars sold by all the given stores together in Jan and total number of cars sold by all the given stores together in April?
(a) 353
(b) 379
(c) 363
(d) 347
Solution:
Total number of cars sold by all the given stores together in Jan = 133 + 161 + 213 + 225 + 282 + 196 = 1210
Total number of cars sold by all the given stores together in April = 178 + 272 + 269 + 284 + 293 + 277 = 1573
Required difference = 1573 – 1210 = 363, Answer C
5. What is the respective ratio between total number of cars sold by stores P and R together in March and total number of cars sold by stores T and U together in May?
(a) 9:11
(b) 11:13
(c) 5:7
(d) 13:17
Solution:
Total number of cars sold by stores P and R together in March = 278 + 226 = 504
Total number of cars sold by stores T and U together in May = 379 + 237 = 616
Ratio= 504 : 616 = 9 : 11, Answer A
Directions: Study the table and answer the questions that follows:
Data Related to Human Resource of a Multinational Company (X) which has 146 Offices across 8 Countries.
Question 1: If the number of male postgraduate employees in country H is 1800, what percent of female employees in that particular country is postgraduate?
[1] 76
[2] 74
[3] 72
[4] 64
[5] 68
In country H, 80% are postgraduate. That is = [80/100]*3360 = 2688
Male is given 1800. Hence, female postgraduate employees = 2688 – 1800 = 888
Total female employees is = [5/14]*3360 = 1200
Hence, required percentage = [888/1200]*100 = 74 Percent. Answer [2] is correct.
Question 2: In which of the given countries is the percentage of women employees to the number of employees (both male and female) in that country the second lowest?
[1] G
[2] B
[3] E
[4] H
[5] D
These types of question are too much calculative. But you can apply the reasoning process to solve these questions a little more quickly. The question asks the percentage of female to total employees. This can be arrived at from the ratio that’s given in the table under the third column. So, just focus upon that ratio and focus upon the countries given in the options. (I.e. Countries G, B, E, H and D only).
Country B = 11:5 à [5/16]*100
Now, let’s say this is approximately 30% (16*3 = 48 which is close to 50).
Country D = [2/5]*100 = 40%
Country E = [6/13]*100 = approx. 45%
Country G = [7/15]*100 = approx. 45%
Country H = [5/14]*100 = approx. 35%
Now, second highest is Country H. Question solved. Answer [4] is correct.
Question 3: What is the respective ratio between total number of male employees in countries B and H together and total number of female employees in countries C and D together?
[1] 63:52
[2] 51:38
[3] 77:64
[4] 69:44
[5] 57:40
These sort of questions requires faster calculation. No other alternative is there!
Total male employees from countries B and H = [11/16]*2880 + [9/14]*3360 = 1980 + 2160 = 4140
Total female employees from Countries C and D = [11/21]*2310 + [2/5]*3575 = 1210 + 1430 = 2640
Required ratio = 4140:2640 = 69:44. Answer [4] is correct.
Question 4: What is the difference between average number of postgraduate employees in countries A, B and D together and average number of postgraduate employees in countries F, G and H together?
[1] 282
[2] 276
[3] 316
[4] 342
[5] 294
Again. Mastery at calculation is required. But here’s a reasoning approach to simplify the calculations.
75% of 2568 is required. Divide 2788 in four parts and add three parts. Thus 2568/4 is 642 and 642*3 = 1926
65% of 2880 is required. Divide 2880 in ten parts and add six parts and half of 7^{th} part. Thus 288*6 + 288/2 = 1728 + 144 = 1872
60% of 3575 is required. Divide 3575 in 5 parts and add three parts. Thus 3575/5 = 715 and 715*3 = 2145
Average of these three is = [1/3]*[1926+1872+2145] = 1981
Using similar procedures, average of other three is calculated as = 2275
Difference = 2275 – 1981 = 294. Answer [5] is correct.
Question 5: Which of the given countries has the highest number of average employees per office?
[1] F
[2] H
[3] B
[4] C
[5] D
This question is similar to question no. 2. Calculating the averages of the given options only gives
B = 2880/18 = 1440/9 = 160
C = 2310/14 = 330/2 = 165
D = 3575/22 = 325/2 = 162.5
F = 2788/17 = 164
H = 3360/21 = 480/3 = 160
Highest is in country C.
Answer [4] is correct.

For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
For 35 AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
For 55 AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
