Container Z has thrice as much water as Container Y. If Reggie adds 0.5 ℓ of water to Container Z and 1.8 ℓ of water to Container Y, both containers will have the same volume of water. Find the volume of water in Container Z at first.

Y |
Z |
Before |
1 u |
3 u |
Change |
+ 1.8 |
+ 0.5 |
After |
1 u + 1.8 |
3 u + 0.5 |
Both containers have the same volume of water in the end.
3 u + 0.5 = 1 u + 1.8
3 u - 1 u = 1.8 - 0.5
2 u = 1.3
1 u = 1.3 ÷ 2 = 0.65
Volume of water in Container Z at first
= 3 u
= 3 x 0.65
= 1.95 ℓ
Answer(s): 1.95 ℓ
