- Initial Income and Savings: The person initially saves 20% of their income.

- Income Increase: The income increases by 25% within a year.

- Constant Savings: Despite the income increase, the savings amount remains the same as before.

- Expenditure Calculation:

- Initially, expenditure was 80% of the income (since 100% - 20% savings = 80%).

- With the new income, the total income becomes 1.25 times the original income.

- Assuming original income was $100, the new income is $125.

- Savings remain $20; thus, expenditure becomes $125 - $20 = $105.

- Initially, outgo was $80; now it is $105.

- Expenditure Increase:

- Increase = New Expenditure ($105) - Old Expenditure ($80) = $25.

- Percentage increase = ($25 / $80) * 100 = 31.25%.

- Correct Option: Option 2: 31.25%.
