CAR
1)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
š 2X + ¼ = 4 ½ => 2X = 4 ½ - ¼ => 2X = 4 ¼
=> X= 2 gallons approx
