Introduction

Data Tables or table Chart is said to be the easiest form of Data Interpretation. Being easier to interpret, questions asked under this in Banking exams are generally based on simple calculations. In Data Tables, data is presented in the form of a table as shown below.

Sample Question

Directions: Study the table and answer the questions that follow:

Data Related to Human Resources of a Multinational Company (X) which has 146 Offices across 8 Countries.

Question 1: If the number of male post-graduate employees in country H is 1800, what percent of female employees in that particular country is post-graduate?

[1] 76
[2] 74
[3] 72
[4] 64
[5] 68

In country H, 80% are post-graduate. That is = [80/100]*3360 = 2688
The Male is given 1800. Hence, female post-graduate 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 lowest is Country H. Question solved. Answer [4] is correct.

Question 3: What is the respective ratio between the total number of male employees in countries B and H together and the 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 the average number of post-graduate employees in countries A, B and D together and the average number of post-graduate 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 into four parts and add three parts. Thus 2568/4 is 642 and 642*3 = 1926
65% of 2880 is required. Divide 2880 into ten parts and add six parts and half of 7th part. Thus 288*6 + 288/2 = 1728 + 144 = 1872
60% of 3575 is required. Divide 3575 into 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, an average of the 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.

Directions: Study the table carefully to answer the questions that follow.

= 87 + 90 + 96 + 67.5 + 52.5 + 45 + 54 + 33 = 525 

Hence option C is correct

2.what are the average marks obtained by all students together in Physics?

B. 56.5 
C. 64.25 
D. 48.88 
E. None of these
 
Ans. B. 

Required average marks obtained = 452 × (75/100) × (1/6) = 56.5 

Hence option B is correct

A. Three 
B. Two 
C. One 
D. None 
E. None of these 

Ans. A. 

Bakul, Chaitanya and Gauri scored the highest marks in more than one subject 

Hence option A is correct

4. Marks obtained by Ankita in Sanskrit are what per cent of marks obtained by Gauri in the same subject? (rounded off to two digits after decimal)

A. 91.43 
B. 94.29
C. 103.13 
D. 109.38
E. None of these

Ans. D. 

Required percentage = (70 × 100)/64 = 109.38 

Hence option D is correct

5. Who has scored the highest marks in all the subjects together?

A. Chaitanya 
B. Himani
C. Deepali
D. Gauri
E. None of those.

Ans. E. 

Total marks scored by Ankita = 90 + 96 + 100.5 + 73.75 + 52.5 + 48.75 + 51 + 35 = 547.5 
Similarly 
Total marks cored by Bakul=726.25 
Total marks scored by Chaitanya = 647.25 
Total marks scored by Deepali =554.75 
Total marks scored by Gauri =614.5 
Total marks scored by Himani = 525 

Thus highest marks are scored by Bakul.

These were some examples of questions based on a table chart. Practice as many questions as you can to get a good hold over the topic.
