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?

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 = XTherefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½ 2X + ¼ = 4 ½ => 2X = 4 ½ - ¼ => 2X = 4 ¼ => X= 2 1/8 . approxTherefore the fuel consumed while coming = 2.125 gallon

I think my answer will be 2 gallon of fuel consumed while coming.

the fuel consumed while going = X + (1/4)X

the fuel consumed while coming = X

the fule consumed for the trip = X+((1/4)X)+X = 4.5

Therefore the fuel consumed while coming = 2 gallon

Tell me, if I am wrong.

In the question, it is said that while going, 1/4 gallon more is consumed and not 1/4 th more oil of the oil consumed..So ur equation X+(1/4*X) will be incorrect.It will actually be X+1/4 while going..

here x+x+1/4 = 4 1/2, then 2x+1/4=9/2,

then 2x=9/2-1/4,
2x=17/4, x=17/8, x=2.125

very imp

 for coming up
2.125+ 1/4,
so 2.125+0.25=2.375

the correct ans is 2.375

2.125 is not the right answer

 we need to add 1/4 to that to get the fuel consumed while coming up

the right ans is 2.125+0.25=2.375

total fuel=4.5 gallons
let amount of fuel for coming=x so a.t.q amonut of fuel for going = x+ x/4=5x/4.
so 5x/4+x<=4.5(as this is not mention that all the fuel is spent during the trip.)
so 9x<=18, x<=2 gallons
