Bucket H has thrice as much water as Bucket G. If Ian adds 0.4 ℓ of water to Bucket H and 2.1 ℓ of water to Bucket G, both buckets will have the same volume of water. Find the volume of water in Bucket H at first.

G |
H |
| Before |
1 u |
3 u |
| Change |
+ 2.1 |
+ 0.4 |
| After |
1 u + 2.1 |
3 u + 0.4 |
Both buckets have the same volume of water in the end.
3 u + 0.4 = 1 u + 2.1
3 u - 1 u = 2.1 - 0.4
2 u = 1.7
1 u = 1.7 ÷ 2 = 0.85
Volume of water in Bucket H at first
= 3 u
= 3 x 0.85
= 2.55 ℓ
Answer(s): 2.55 ℓ
