Solved Examples 
A table chart, alternatively referred to as a data table, presents data in a visual format with organized rows and columns. In this representation, each row usually signifies a data point or record, and each column corresponds to a variable or attribute.
A mathematical line chart is a visual depiction of mathematical functions or equations presented on a twodimensional plane. Its purpose is to illustrate the correlation between two variables, typically an independent one (such as time, distance, or input) and a dependent one (like temperature, velocity, or output). Employed across diverse disciplines such as mathematics, physics, engineering, economics, and others, mathematical line charts serve as a tool to showcase and examine continuous data trends and mathematical connections.
Various types of table charts are available for representing data, including the following commonly used ones:
Example 1: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
What is the difference between the total number of Technicians added to the Company and the total number of Accountants added to the Company during the years 2016 to 2020?
(a) 128
(b) 112
(c) 96
(d) 88
Ans: (d)
Required difference
= (272 + 240 + 236 + 256 + 288)  (200 + 224 + 248 + 272 + 260)
= 88.
Example 2: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
What was the total number of Peons working in the Company in the year 2019?
(a) 1312
(b) 1192
(c) 1088
(d) 968
Ans: (b)
Total number of Peons working in the Company in 2019
= (820 + 184 + 152 + 196 + 224)  (96 + 88 + 80 + 120) = 1192.
Example 3: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
For which of the following categories the percentage increase in the number of employees working in the Company from 2015 to 2020 was the maximum?
(a) Managers
(b) Technicians
(c) Operators
(d) Accountants
Ans: (a)
Number of Managers working in the Company:
In 2015 = 760.
In 2020 = (760 + 280 + 179 + 148 + 160 + 193)  (120 + 92 + 88 + 72 + 96)= 1252.
Therefore, the Percentage increase in the number of Managers
(1252  760) / 760 * 100 = 64.74%
Number of Technicians working in the Company:
In 2015 = 1200.
In 2020 = (1200 + 272 + 240 + 236 + 256 + 288)  (120 + 128 + 96 + 100 +112) = 1936.
Therefore, the Percentage increase in the number of Technicians
{(1936  1200 ) / 1200} * 100 = 61.33%
Number of Operators working in the Company:
In 2015 = 880.
In 2020 = (880 + 256 + 240 + 208 + 192 + 248)  (104 + 120 + 100 + 112 + 144) = 1444.
Therefore, the Percentage increase in the number of Operators
(1444  880 / 880 ) * 100 = 64.09%
Number of Accountants working in the Company:
In 2015 = 1160.
In 2020 = (1160 + 200 + 224 + 248 + 272 + 260)  (100 + 104 + 96 + 88 + 92) = 1884.
Therefore, the Percentage increase in the number of Accountants
(1884  1160 / 1160 ) * 100 = 62.14%
Number of Peons working in the Company:
In 2015 = 820.
In 2020 = (820 + 184 + 152 + 196 + 224 + 200)  (96 + 88 + 80 + 120 + 104) = 1288.
Therefore, the Percentage increase in the number of Peons
(1288  820 / 820 ) * 100 = 57.07%
Clearly, the percentage increase is maximum in the case of Managers.
Example 4: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
What is the pooled average of the total number of employees of all categories in the year 2017?
(a) 1325
(b) 1195
(c) 1265
(d) 1235
Ans: (b)
Total number of employees of various categories working in the Company in 2017 are:
Managers = (760 + 280 + 179)  (120 + 92) = 1007.
Technicians = (1200 + 272 + 240)  (120 + 128) = 1464.
Operators = (880 + 256 + 240)  (104 + 120) = 1152.
Accountants = (1160 + 200 + 224)  (100 + 104) = 1380.
Peons = (820 + 184 + 152)  (96 + 88) = 972.
Therefore, Pooled average of all the five categories of employees working in the Company in 1997 = 1/5 x (1007 + 1464 + 1152 + 1380 + 972)
= 1/5 x (5975)
= 1195.
Example 5: The following table shows the number of new employees added in Kia Motors India, in different categories and also the number of employees from these categories who left the company every year.
During the period between 2015 and 2020, the total number of Operators who left the Company is what percent of the total number of Operators who joined the Company?
(a) 19%
(b) 21%
(c) 27%
(d) 29%
Ans: (d)
Total number of Operators who left the Company during 2015  2020
= (104 + 120 + 100 + 112 + 144)
= 580.
Total number of Operators who joined the Company during 2015  2020
= (880 + 256 + 240 + 208 + 192 + 248
= 2024.
Therefore, Required Percentage
= (580/2024) x 100% = 28.66% ~= 29%.
