The cup originally contained 800 ml of water. Pour the water into the cup. The consumption situation is as shown in the picture on the right. Find the water in the cup.

If you use an equation to solve:

Suppose: A originally had X milliliters of water, and B originally had Y milliliters of water.

Then X+Y=800

X-50-(y+50)=30

The final solution is X=465, Y=335
