The gasoline gauge on a van initially read 1/3 full. When 10 gallons were added to the tank, the gauge read 3/4 full. How many more gallons are needed to fill the tank?

Given :
Let the total gallon of gas be x
Then,
Intial gasoline = 1/ 3 x
Now, after 10 gallons of gas is added, gasoline is 3/ 4 x
So,
3/ 4 x - 1/ 3 x = 10
(9 - 4)x/12= 10
5x/12 = 10
x = 10 × 12/5
x = 24
Hence, 24 gallons of gas is needed to fill the tank.
