Answer 2

◘ Given:-

• Income of a person = Rs. 135000
• Savings of the person = Rs. 4500
• Income percentage increased by 16%
• Expenditure percentage increased by 8%

◘ To Find:-

• Percentage increased in Savings of the person.

◘ Solution:-

WKT

• Expenditure = Total Income - Savings.

➝ Rs.13500 - Rs.4500

➝ Rs. 9000

Actually Expenditure is Rs.9000.

Now, New Increased

• New Income = Actual Income+% increased.

Actual Income = Rs.13500

Percentage Increased = 16%

➝ Rs.13500+16% of Rs.13500

➝ Rs.13500 + [16/100×13500]

➝ Rs.13500 + [16×135]

➝ Rs.13500 + Rs.2160

➝ Rs.15660

New Income is Rs.15660

• New Expenditure = Actual Expenditure+% increased.

Actual Expenditure = Rs.9000

Percentage Increased = 8%

➝ Rs.9000 + 8% of Rs.9000

➝ Rs.9000 + [8/100×9000]

➝ Rs.9000 + [8×90]

➝ Rs.9000 + 720

➝ Rs.9720

New Expenditure is Rs.9720

• New Savings = New Income - New Expenditure.

➝ Rs.15660 - Rs.9720

➝ Rs. 5940

New Savings is Rs.5940

• Savings Increased = New Savings - Actual Savings

➝ Rs.5940 - Rs.4500

➝ Rs.1440

• Percentage Increased = Savings Increased÷Actual Savings × 100%.

➝ 1440/4500×100%

➝ 1440/45%

➝ 32%

Saving Increased Percentage is 32%

• Required Value ☞ 32%
