You have two empty water jugs in your hands. One holds 3 gallons of water, the other holds 5 gallons of water.
You need to use these two jugs to measure exactly 4 gallons of water.
The answer is: 
To measure exactly 4 gallons of water using a 3-gallon jug and a 5-gallon jug, you can follow these steps:
1.	Select the bigger gallon jug and fill it with water completely.
2.	Pour the water from the bigger gallon jug (5-gallon jug in our case) into the smaller gallon jug (3-gallon jug in this case) until the smaller gallon jug is full, leaving you with (subtract the values 7-5 = 2 gallons of water in this case ) in the bigger gallon (5-gallon jug in this case).
3.	Empty the smaller gallon jug (3-gallon jug).
4.	Pour the 2 gallons of water (7-5=2) from the bigger gallon jug (5-gallon jug) into the smaller gallon jug (3-gallon jug).
5.	Fill the bigger gallon jug (5-gallon jug) with water again.
6.	Pour water from the bigger gallon jug (5-gallon jug) into the smaller (3-gallon jug )until the smaller gallon jug (3-gallon jug) is full, which will leave you with 4 gallons of water in the 5-gallon jug.
Now you have measured exactly 4 gallons of water using the 3-gallon and 5-gallon jugs.

If provided with different values determine the bigger and smaller gallon jug and continue in the same pattern until getting the correct answer

now, You have two empty water jugs in your hands. One holds 7 gallons of water, the other holds 5 gallons of water. You need to use these two jugs to measure exactly 6 gallons of water.
