Direction: Study the table given below carefully and answer the following question. Year Items of Expenditure Salary Food Medicine Tax 2001 Rs. 1,500 Rs. 200 Rs. 500 Rs. 100 2002 Rs. 2,600 Rs. 300 Rs. 600 Rs. 200 2003 Rs. 3,200 Rs. 150 Rs. 700 Rs. 150 2004 Rs. 4,100 Rs. 250 Rs. 650 Rs. 125 2005 Rs. 5,000 Rs. 200 Rs. 800 Rs. 150 2006 Rs. 5,200 Rs. 100 Rs. 750 Rs. 175
The average salary per year during period 2001 – 2006 is:
3,600
Calculate Average Salary from Table Data
To find the average salary per year during the period 2001 to 2006, we need to sum up the salaries for each year and then divide by the total number of years in that period.
Data Extraction: Salaries by Year (2001-2006)
Let's first identify the salary figures for each specified year from the provided table:
| Year | Salary (Rs.) |
|---|---|
| 2001 | 1,500 |
| 2002 | 2,600 |
| 2003 | 3,200 |
| 2004 | 4,100 |
| 2005 | 5,000 |
| 2006 | 5,200 |
Steps to Calculate Average Salary
-
Sum of Salaries: Add the salary values for each year from 2001 to 2006.
Sum $= 1500 + 2600 + 3200 + 4100 + 5000 + 5200$
Sum $= 21600$
- Number of Years: Count the number of years from 2001 to 2006. There are 6 years (2001, 2002, 2003, 2004, 2005, 2006).
-
Calculate Average: Divide the total sum of salaries by the number of years.
Average Salary per year $= \frac{\text{Sum of Salaries}}{\text{Number of Years}}$
Average Salary per year $= \frac{21600}{6}$
Average Salary per year $= 3600$
Final Average Salary Result
The average salary per year during the period 2001 – 2006 is Rs. 3,600.
Revision Table: Data Analysis and Averages
Calculating the average is a fundamental statistical operation used to find a central value in a set of numbers.
| Concept | Definition | Formula | Application in this problem |
|---|---|---|---|
| Average (Mean) | The sum of a set of values divided by the number of values. | $\text{Average} = \frac{\text{Sum of values}}{\text{Number of values}}$ | Used to find the typical annual salary over the 6-year period. |
| Data Interpretation | Analyzing and extracting meaningful information from data, often presented in tables, charts, or graphs. | N/A | Reading the table to get salary figures for each year. |
Additional Information: Understanding Data Tables
Data tables are a common way to organize information. They use rows and columns to present data clearly. In this question, the table shows different items of expenditure for different years. Each row represents a year, and each column represents a specific expenditure item like Salary, Food, Medicine, or Tax.
When working with data tables, it's important to:
- Read the column and row headers carefully to understand what the data represents.
- Locate the specific data points needed for the calculation (in this case, the salary figures).
- Ensure you are using data for the correct time period (2001-2006).
- Perform the required mathematical operations accurately (summation and division for average).
Understanding how to read and interpret data from tables is crucial for solving many quantitative reasoning problems. The average calculation provides a single value that summarizes the salary trend over the given years.
