Answer:

780 Rs

Step-by-step explanation:

  1. Work out how far 1 litre of petrol will take you - we know the car goes 121 km on 11 litres, so 121/ 11 = 11. Therefore the care goes 11km per litre of fuel.
  2. Find how many litres of fuel are needed to go 143 km: 143/ 11 = 13, so the car needs 13 litres of fuel.
  3. Find how much this costs: we have 13 litres at 60 Rs each. So 13 x 60 = 780 Rs

Hope this helps, feel free to ask if you have any questions :)
