Question
Monthly income of P is Rs.16000 and his monthly savings
is Rs.10500. If his monthly income is decreased by 25% and monthly expenditure is decreased by 10% then find the approximate percentage decrease in his monthly savings.Solution
ATQ,
Given: Income = Rs. 16,000 Savings = Rs. 10,500 Expenditure = Rs. 16,000 - Rs. 10,500 = Rs. 5,500 After Changes: Income decreases by 25%: New income = Rs. 16,000 - 25% of Rs. 16,000 = Rs. 12,000 Expenditure decreases by 10%: New expenditure = Rs. 5,500 - 10% of Rs. 5,500 = Rs. 4,950 New savings = Rs. 12,000 - Rs. 4,950 = Rs. 7,050 Percentage decrease in savings: 
The percentage decrease in savings is approximately 32.86% .
