the ratio of Big Tang to small tang is 3: 1. How much water have added to each tang?

My answer is 190l but didn't know whether my working is correct. Please help Smile

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
Water Added
= 1 Unit - 170L
= 360L - 170L
=190L
