Question

There was a cup with tea in it and they weighed 200g altogether.

After I drank half of the tea, they then weighed 160g. How many
grams does this cup weigh?

Answer 1

120g is how much the cup weighs:)) hope this helped!!! explanation - 40g is half the tea so multiply that by 2 you get 80g. take the total weight of the tea and cup 200g and subtract the total weight of the tea 80g and you will get the remaining weight of just the cup at 120g.
