If one were to travel from Bangalore to Goa, which is approximately 600 km, how many times would the tank have to be refilled to cover the distance to and from Goa? The terrain is not hilly but just plane roads. This would help in calculating the total fuel cost for the trip.

Compared to Maruti Suzuki Swift Dzire which has a tank of 42 liters, the tank capacity of Maruti Suzuki Dzire is 37 liters. As you mention, the distance between the two locations in your trip is approximately 600km, the total distance to be covered to and from would be 1200 km. The mileage provided by the car is 21-28 kmpl, so roughly you would need a maximum of 58 liters.
So accordingly you would need a tank refill 1.5 times. Based on the fuel costs, you should be able to calculate the maximum amount you would need to spend. This is, however, the maximum considering the mileage to be 21 kmpl.
