Step-by-step explanation:
% increase = Increase ÷ Original Number × 100.
1 litre petrol price ( before increment ) = ₹90
1 litre petrol price ( after increment ) = ₹100
Mr. Roy needs 3 litres of Petrol everyday for his scooter
Price of 3 litres of petrol before increment = 90 × 3 = ₹270
Price of 3 litres of petrol after increment = 100 × 3 =
₹300
Hence percentage of increment in his daily expenses for petrol is = 300 - 270 / 270 × 100
=> 30/270 × 100
=> 1/90 × 100
=> 100/90
=> 10/9
=> 1.12% of increment
