Calculating Monthly Salary from Spending and Savings
To find the man's monthly salary, we need to calculate his total annual income. This is done by summing his total annual spending and his annual savings.
Step 1: Calculate Total Spending (January to July)
The man spends ₹ 3500 per month for 7 months (January to July).
Total spending for these 7 months = $7 \times ₹ 3500 = ₹ 24500$
Step 2: Calculate Total Spending (August to December)
He spends ₹ 3800 per month for 5 months (August to December).
Total spending for these 5 months = $5 \times ₹ 3800 = ₹ 19000$
Step 3: Calculate Total Annual Spending
Add the spending from both periods:
Total Annual Spending = $₹ 24500 + ₹ 19000 = ₹ 43500$
Step 4: Calculate Total Annual Income
The total annual income is the sum of total annual spending and annual savings.
Annual Savings = ₹ 9000
Total Annual Income = $₹ 43500 + ₹ 9000 = ₹ 52500$
Step 5: Calculate Monthly Salary
Divide the total annual income by 12 months to find the average monthly salary.
Monthly Salary = $₹ 52500 / 12 = ₹ 4375$
Therefore, the man's monthly salary is ₹ 4375.
