Correct Answer :B - ₹20
Detailed Text Solution
Distance travelled per month = 3045 km
Mileage = 15 km per litre
Petrol required per month = 3045 / 15
= 203 litres
Original price = ₹2 per litre
After 5% increase:
New price = 2 × 1.05 = ₹2.10 per litre
Increase per litre = 2.10 − 2 = ₹0.10
Increase in monthly expenditure = 203 × 0.10
= ₹20.3
To the nearest rupee, increase = ₹20.
