💡 Analysis & Explanation
Financial Distribution Logic ▼
A fundamental principle of personal finance is that total Income is exactly equal to the sum of Savings and Expenditure. By default, total income is represented as 100%.
Percentage Calculation ▼
The problem explicitly states the person saves 40% of their income. Consequently, the remaining portion dedicated to expenditure must be 100% - 40% = 60%.
Value Equivalence Setup ▼
We are given the actual monetary value of the expenditure, which is ₹960. Therefore, 60% of the total unknown income equates to 960. Mathematically, 0.60 * Income = 960.
Final Derivation ▼
To find the total 100% income, we divide the monetary value by its decimal percentage: Income = 960 / 0.60 = 1600.
Conclusion ▼
The exact initial income of the person is ₹1,600.
