Answer 2

Money spent by them to buy fuel for the journey from Asansol to Kolkata​ was Rs 210.8.

Given:

A motorbike goes 80 km in 1 liter of petrol.

Each liter of petrol costs Rs.80.

To Find:

The money spent by them to buy fuel for the journey from Asansol to Kolkata.

Solution:

The distance between Asansol and Kolkata is 210.8 km.

Step 1: Find the amount of petrol required to travel 1 km.

We are given that a motorbike goes  80km in 1 liter.

⇒ The petrol required by the motorbike to travel 1 km = (1/80) liters

Step 2: Find the total petrol required to travel from Asansol to Kolkata.

Total petrol required = Total distance between Asansol and Kolkata x Petrol required to travel 1 km.

⇒ Total petrol required = 210.8 x (1/80) = 2.635 liters.

Hence the total petrol required for the entire journey = 2.635 liters.

Step 3: Find the total money spent on the fuel.

We are given that each liter of petrol costs Rs.80.

Total money spent on the fuel = Total petrol required for the entire journey x charge of 1 liter of petrol.

⇒ Total money spent on the fuel = 2.635 x 80 = Rs. 210.8

∴ Money spent by them to buy fuel for the journey from Asansol to Kolkata​ was Rs 210.8.
