Big Tang filled with 890l of water while small tang filled with 170l of water. After same amount of water were added into both tangs,
the ratio of Big Tang to small tang is 3: 1. How much water have added to each tang?

Yes it is 190L.

Since the same amount of water was added, therefore

2 Units = 890 - 170 = 720L
1 Unit = 360L

Now 1 Unit = Water Added + 170L, therefore
= 1 Unit - 170L
= 360L - 170L
=190L
