Quantitative Aptitude | Question 3 of 49

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 = 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 1/8 . approx

Therefore the fuel consumed while coming = 2.125 gallon

RE: A car is filled with four and half gallons of oil ...

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.

RE: A car is filled with four and half gallons of oil ...

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..
