Table Charts (original) (raw)

Last Updated : 23 Dec, 2025

A table chart is a widely used and highly effective method of organizing numerical data, especially when accuracy and detailed comparison are required. It presents information in a structured format using rows and columns, allowing values to be read, compared, and analyzed systematically. This arrangement makes it easier to perform calculations such as totals, averages, percentages, and ratios, helping candidates interpret data efficiently without unnecessary visual complexity.

**Example: A table showing the annual sales of different products across multiple years can be used to compare growth, calculate percentages, and identify trends efficiently.

The data below shows A, B, C, D, and E school and their marks in subjects.

Solved Questions on Table Charts

**Example 1: The table below shows the number of students enrolled in different branches of an institute.

Branch Students
CSE 120
ECE 100
ME 80
CE 60

**Question 1: What is the total number of students in the institute?

Solution:

Total = 120 + 100 + 80 + 60 = 360

**Question 2: If 20% of CSE students, 25% of ECE students, 50% of ME students, and 40% of CE students participate in a technical fest, what is the total number of participants? Also, what fraction of total students participates?

**Solution:

Participants from each branch:

**Question 3: What is the ratio of students in CSE and ECE together to the students in ME and CE together?

**Solution:

Students in CSE + ECE = 120 + 100 = 220
Students in ME + CE = 80 + 60 = 140

Required Ratio=220 : 140 = 11 : 7

**Question 4: The total number of students in the institute during the given period is?

**Solution :

120 (CSE) + 100 (ECE) + 80 (ME) + 60 (CE) = 360

**Example 2: Number of Candidates Appeared and Qualified in a Competitive Examination from Different States Over the Years.

**Question 1: What are the average marks obtained by all the seven students in Chemistry ?

**Solution:

Chemistry marks of the seven students:
72, 88, 64, 70, 60, 76, 68

Total marks in Chemistry

72 + 88 + 64 + 70 + 60 + 76 + 68 = 498

Average marks

498/7 ≈ 71.14

**Question 2: The number of students who obtained 50% and above marks in all subjects is?

**Solution:

From the table, it is clear that Arjun, Neha, Riya, Aman, and Simran have obtained 50% or more marks in each of the six subjects.

**Question 3: What is the overall percentage of marks obtained by Arjun?

**Solution:

Total maximum marks

150 + 130 + 120 + 100 + 60 + 40 = 600

Total marks obtained by Arjun

110 + 72 + 95 + 68 + 45 + 32 = 442

Overall percentage

422/600 ×100 = 70.33%
