We are going to discuss here a simple way to solve 10 7 3 liter puzzle.

10 7 3 liter puzzle :

We have 3 different water jugs, 3 liter water jug, 7 liter water jug and 10 liter water jug. 10 liter water jug is filled with water. Now we need to measure that 10 liter water equally that means 5 Liter one jug and 5 liter in another jug.

Solution: 

If we carefully observe the problem statement of the puzzle then you will realize that this is same type of another puzzle we solve where we measure some water based on jugs we have.

Here in this case if you are able to measure 5 liter water than the remaining water will be 5 liter.

Step 1: Fill 7 liter water jug from 10 liter water jug.

Step 2: Put 3 liters from 7 liter water jug into 3 liter water jug.
Now 3 liter jug contains 3 liter water, 7 liter water jug contains 4 liter water and 10 liter water jug contains 3 liter water.

Step 3: Now put 3 liter water from 3 liter jug into 10 liter jug and put 3 liter water from 7 liter jug into 3 liter jug.
Now 3 liter jug contains 3 liter water, 7 liter water jug contains 1 liter water and 10 liter water jug contains 6 liter water.

Step 4:  Now put 3 liter water from 3 liter jug into 10 liter jug and put remaining 1 liter water from 7 liter jug into 3 liter jug.
Now 3 liter jug contains 1 liter water, 7 liter water jug contains 0 liter water and 10 liter water jug contains 9 liter water.

Step 5:  Fill 7 liter water from 10 liter jug to 7 liter jug. Since 3 liter jug has 2 liter empty space, put 2 liter water from 7 liter jug into 3 liter jug.
Now 3 liter jug contains 3 liter water, 7 liter water jug contains 5 liter water and 10 liter water jug contains 2 liter water.

Step 6: Solved! Now 7 liter jug contains 5 liter water and if we put 2 liters from 3 liter jug into 10 liter jug. Then 10 liter jug will contain 5 liter water.

Logic:

(7 * 2) - (3 * 3) = 5

If we able to measure 5 liter water then traumatically remaining water will be 5 liter.

As mentioned in the above formula we need to fill 7 liter jug 2 times and empty that into 3 liter jug then we can measure 5 liter water.
