Solution

Here is the step-by-step calculation for the percentage increase in savings.

1. Initial Savings

• Initial Income = Rs. 10,000
• Initial Expenditure = Rs. 6,000
• Initial Savings = 10,000 - 6,000 = Rs. 4,000

2. New Income and Expenditure

• New Income = 10,000 + (15% of 10,000) = 10,000 + 1,500 = Rs. 11,500
• New Expenditure = 6,000 + (8% of 6,000) = 6,000 + 480 = Rs. 6,480

3. New Savings

• New Savings = 11,500 - 6,480 = Rs. 5,020

4. Percentage Increase in Savings

• Increase in Savings = New Savings - Initial Savings = 5,020 - 4,000 = Rs. 1,020
• Percentage Increase = (Increase / Initial Savings) × 100
• Percentage Increase = (1,020 / 4,000) × 100 = 25.5%
