Q: A person travels the various distances by rail, bus, and vehicle in the following order: 4: 3: 2. The fair has a 1: 2: 4 per kilometre ratio. The overall cost of the fair is Rs 720. Determine the total cost of the train ride.
Distance covered in the ratio T: B: C = 4: 3: 2
Fair ratio per km. T: B: C = 1: 2: 4
So, the ratio of total fair T: B: C = 4: 6: 8
Sum of the ratio of total fair = 18
But ATQ, it is 720, so multiply 18 by 40.
Now, multiply each and every ratio with 40.
The total expenditure as fair on a train = 4*40=160
