Pail F has thrice as much water as Pail E. If Warren adds 1.2 ℓ of water to Pail F and 2.5 ℓ of water to Pail E, both pails will have the same volume of water. Find the volume of water in Pail F at first.

E |
F |
| Before |
1 u |
3 u |
| Change |
+ 2.5 |
+ 1.2 |
| After |
1 u + 2.5 |
3 u + 1.2 |
Both pails have the same volume of water in the end.
3 u + 1.2 = 1 u + 2.5
3 u - 1 u = 2.5 - 1.2
2 u = 1.3
1 u = 1.3 ÷ 2 = 0.65
Volume of water in Pail F at first
= 3 u
= 3 x 0.65
= 1.95 ℓ
Answer(s): 1.95 ℓ
