Problem Statement: The income of a person is 10000 and its expenditure is 6000 and thus saves 4000rs. In the next year his income is increased by 10% and its expenditure increased by 20%. Now his saving is what percent lower than the previous saving.?

Solution:

Given:

  • Income = 10000

  • Expenditure = 6000

  • Saving = 4000

  • Income increased by 10%

  • Expenditure increased by 20%



Step 1: Calculation of Income and Expenditure in the next year

  • New Income = 10000 + 10% of 10000 = 11000

  • New Expenditure = 6000 + 20% of 6000 = 7200



Step 2: Calculation of new Savings

  • New Savings = New Income - New Expenditure

  • New Savings = 11000 - 7200 = 3800



Step 3: Calculation of Percentage change in Savings

  • Percentage change in Savings = ((Previous Savings - New Savings)/Previous Savings) * 100

  • Percentage change in Savings = ((4000 - 3800)/4000) * 100

  • Percentage change in Savings = (200/4000) * 100

  • Percentage change in Savings = 5%



Answer: The new saving is 5% lower than the previous saving.
