The price of fuel increases by 10%, and a person reduces
his usage by 5%. Find the percentage increase or decrease in his expenditure.Solution

Initial expenditure = Rs. xy
New increased price = Rs. 1.10y
Reduced usage = 0.95x
New expenditure = 1.10y × 0.95x = Rs. 1.045xy
Hence, the expenditure increases by 4.5%.
