Verified Answer
The income of a person is Rs. 45000 and his expenditure is Rs. 33000. ...
Initial income = Rs. 45000
Initial Expenditure = Rs. 33000
Savings = Rs. 45000 - Rs. 33000 = Rs. 12000
New Income = 45000 + 22% of 45000 = Rs. 54900
New Expenditure = 33000 + 11% of 33000 = Rs. 36630
New savings = 18270
∴ Percentage increase in savings = [(18270 - 12000)/12000] × 100 = 52.25%

The income of a person is Rs. 45000 and his expenditure is Rs. 33000. ...
To calculate the percentage increase in savings, we need to find the difference between the new income and new expenditure, and then calculate the percentage increase in this difference.
Given:
Income = Rs. 45000
Expenditure = Rs. 33000
Step 1: Calculate the new income
New income = Income + (22% of Income)
= 45000 + (0.22 * 45000)
= 45000 + 9900
= 54900
Step 2: Calculate the new expenditure
New expenditure = Expenditure + (11% of Expenditure)
= 33000 + (0.11 * 33000)
= 33000 + 3630
= 36630
Step 3: Calculate the difference between new income and new expenditure
Difference = New income - New expenditure
= 54900 - 36630
= 18270
Step 4: Calculate the percentage increase in savings
Percentage increase = (Difference / Expenditure) * 100
= (18270 / 33000) * 100
= 55.36%
Therefore, the percentage increase in savings is approximately 55.36%, which is closest to option D) 52.25%.
Given:
Income = Rs. 45000
Expenditure = Rs. 33000
Step 1: Calculate the new income
New income = Income + (22% of Income)
= 45000 + (0.22 * 45000)
= 45000 + 9900
= 54900
Step 2: Calculate the new expenditure
New expenditure = Expenditure + (11% of Expenditure)
= 33000 + (0.11 * 33000)
= 33000 + 3630
= 36630
Step 3: Calculate the difference between new income and new expenditure
Difference = New income - New expenditure
= 54900 - 36630
= 18270
Step 4: Calculate the percentage increase in savings
Percentage increase = (Difference / Expenditure) * 100
= (18270 / 33000) * 100
= 55.36%
Therefore, the percentage increase in savings is approximately 55.36%, which is closest to option D) 52.25%.
