A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in go?

Sol :: Before the trip, car is filled with = 4 陆 gallon of oil





Let 鈥榅鈥?be the quantity of fuel consumed for the trip in one


direction





The fuel consumed while going = X + 录





The fuel consumed while coming = X





Therefore, the fuel consumed for the trip = (X + 录) + X = 4 陆





2X + 录 = 4 陆 =%26gt; 2X = 4 陆 - 录 =%26gt; 2X = 4 录 =%26gt; X= 2. approx





Therefore the fuel consumed while coming = 2 gallon
