Q |
R |
| Before |
1 u |
3 u |
| Change |
+ 1.8 |
+ 1.1 |
| After |
1 u + 1.8 |
3 u + 1.1 |
Both buckets have the same volume of water in the end.
3 u + 1.1 = 1 u + 1.8
3 u - 1 u = 1.8 - 1.1
2 u = 0.7
1 u = 0.7 ÷ 2 = 0.35
Volume of water in Bucket R at first
= 3 u
= 3 x 0.35
= 1.05 ℓ
Answer(s): 1.05 ℓ
