Explanation:
- Expenditure Calculation:
- First 3 months: Rs10,000 x 3 = Rs30,000
- Next 4 months: Rs12,500 x 4 = Rs50,000
- Last 5 months: Rs13,500 x 5 = Rs67,500
- Total expenditure for the year = Rs30,000 + Rs50,000 + Rs67,500 = Rs147,500
- Total Income Calculation:
- Total income = Total expenditure + Total savings
- Total income = Rs147,500 + Rs32,500 = Rs180,000
- Average Monthly Income Calculation:
- Average monthly income = Total income ÷ 12 months
- Average monthly income = Rs180,000 ÷ 12 = Rs15,000
- Correct Option: 1 - Rs15,000
