Bucket B has thrice as much water as Bucket A. If Ken adds 0.8 ℓ of water to Bucket B and 1.7 ℓ of water to Bucket A, both buckets will have the same volume of water. Find the volume of water in Bucket B at first.

A |
B |
| Before |
1 u |
3 u |
| Change |
+ 1.7 |
+ 0.8 |
| After |
1 u + 1.7 |
3 u + 0.8 |
Both buckets have the same volume of water in the end.
3 u + 0.8 = 1 u + 1.7
3 u - 1 u = 1.7 - 0.8
2 u = 0.9
1 u = 0.9 ÷ 2 = 0.45
Volume of water in Bucket B at first
= 3 u
= 3 x 0.45
= 1.35 ℓ
Answer(s): 1.35 ℓ
