Explanation:

- Calculate Shifa's total savings for the year:

- First 5 months: Average savings = Rs. 2120 ? Total = 5 × 2120 = Rs. 10,600

- Next 3 months: Average savings = Rs. 4260 ? Total = 3 × 4260 = Rs. 12,780

- Last 4 months: Average savings = Rs. 3140 ? Total = 4 × 3140 = Rs. 12,560

- Total savings = 10,600 + 12,780 + 12,560 = Rs. 35,940

- Calculate Shifa's total expenditure for the year:

- Average expenditure = Rs. 11,000

- Total expenditure for 12 months = 12 × 11,000 = Rs. 132,000

- Determine Shifa's total income for the year:

- Total income = Total savings + Total expenditure

- Total income = 35,940 + 132,000 = Rs. 167,940

- Select the correct option:

- Option 1: Rs. 170,520

- Option 2: Rs. 174,680

- Option 3: Rs. 180,950

- Option 4: Rs. 167,940

- Option 5: Rs. 190,360
