A Correct answer
Explanation

Let the initial income be 100, so the expenditure is 75 and the savings are 25. After the increases, the new income is 120 and the new expenditure is 82.5 (10% more than 75). This leaves new savings of 120 - 82.5 = 37.5, which is a 50% increase from the original savings of 25.

AI explanation

Let the initial income be 100, so at 75 percent expenditure, the spending is 75 and the savings are 25. The new income becomes 120, and increasing the expenditure by 10 percent makes the new spending 82.5, leaving new savings of 120 minus 82.5, which is 37.5. The increase in savings is 37.5 minus 25 equals 12.5; dividing 12.5 by 25 and multiplying by 100 gives a 50 percent increase.
