Consider the following table that presents the details about the percentage distribution of household expenditure of a family on various budget heads during the years 2020 and 2021. The total income of the family in the years 2020 and 2021 was Rs. 50000 and Rs. 75000, respectively. Based on the data in the table, answer the five questions that follow: Budget Head wise Distribution of Expenditure Year → Budget Head ↓2020 2021 Entertainment 11% 9% Health 5% 6% Clothing 25% 25% Food 19% 21% Travel 34% 24% Others 6% 15%
What is the increase in the amount of money spent on the health budget head from 2020 to 2021?
Rs. 2000
Calculating Increase in Health Expenditure (2020-2021)
The question asks us to find the increase in the amount of money spent on the health budget head from the year 2020 to 2021 based on the provided table and total income data.
First, let's note down the relevant information:
- Total income in 2020 = Rs. 50000
- Total income in 2021 = Rs. 75000
- Percentage expenditure on Health in 2020 = 5%
- Percentage expenditure on Health in 2021 = 6%
Now, we need to calculate the actual amount spent on Health in each year.
Amount Spent on Health in 2020
The amount spent on Health in 2020 is 5% of the total income in 2020.
Amount in 2020 = \( \text{5% of Rs. 50000} \)
Amount in 2020 = \( \frac{5}{100} \times 50000 \)
Amount in 2020 = \( 5 \times 500 \)
Amount in 2020 = \( \text{Rs. 2500} \)
Amount Spent on Health in 2021
The amount spent on Health in 2021 is 6% of the total income in 2021.
Amount in 2021 = \( \text{6% of Rs. 75000} \)
Amount in 2021 = \( \frac{6}{100} \times 75000 \)
Amount in 2021 = \( 6 \times 750 \)
Amount in 2021 = \( \text{Rs. 4500} \)
Calculate the Increase in Health Expenditure
The increase in the amount spent on Health from 2020 to 2021 is the difference between the expenditure in 2021 and the expenditure in 2020.
Increase = Amount spent in 2021 - Amount spent in 2020
Increase = Rs. 4500 - Rs. 2500
Increase = Rs. 2000
Therefore, the increase in the amount of money spent on the health budget head from 2020 to 2021 is Rs. 2000.
Summary of Calculations
| Year | Total Income (Rs.) | Health Expenditure (%) | Amount Spent on Health (Rs.) |
|---|---|---|---|
| 2020 | 50000 | 5% | \(50000 \times \frac{5}{100} = 2500\) |
| 2021 | 75000 | 6% | \(75000 \times \frac{6}{100} = 4500\) |
Increase in Health Expenditure = Amount in 2021 - Amount in 2020 = Rs. 4500 - Rs. 2500 = Rs. 2000.
Revision Table: Key Learnings
| Concept | Explanation |
|---|---|
| Percentage Calculation | To find a percentage of a number, convert the percentage to a decimal or fraction and multiply by the number. E.g., 5% of X is \(X \times \frac{5}{100}\). |
| Finding Increase/Decrease | The increase or decrease between two values is the difference between the final value and the initial value. Increase = Final - Initial. |
