20.A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
    
Sol:Before the trip, car is filled with = 4 ½ gallon of oil
    
Let ‘X’ be the quantity of fuel consumed for the trip in one direction

    The fuel consumed while going = X + ¼
    
    The fuel consumed while coming = X

    Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½

     2X + ¼ = 4 ½ => 2X = 4 ½ – ¼ => 2X = 4 ¼ => X= 2. approx

Therefore the fuel consumed while coming = 2 gallon
