Understanding Income Calculation
The problem asks us to find the total income of a person given the percentage of income spent and the amount saved.
- Spending = 80% of Income
- Saved Amount = ₹2000
Calculating Savings Percentage
If a person spends 80% of their income, the remaining portion represents their savings.
Savings Percentage = Total Percentage - Spending Percentage
Savings Percentage = 100% - 80% = 20%
Income Calculation Using Savings
We know that 20% of the person's income is equal to the saved amount, which is ₹2000.
Let the total income be represented by '$I$'.
Using the formula:
Savings Percentage \(\times\) Income = Saved Amount
So, \(20\%\) of \(I = ₹2000\)
Converting the percentage to a decimal:
\(\frac{20}{100} \times I = ₹2000\)
\(0.20 \times I = ₹2000\)
To find the income '$I$', we rearrange the equation:
$I = \frac{₹2000}{0.20}
$I = \frac{₹2000}{\frac{20}{100}}
$I = ₹2000 \times \frac{100}{20}
$I = ₹2000 \times 5
$I = ₹10,000
Conclusion
The person's total income is ₹10,000.
