Pail V has thrice as much water as Pail U. If Ahmad adds 0.5 ℓ of water to Pail V and 2.6 ℓ of water to Pail U, both pails will have the same volume of water. Find the volume of water in Pail V at first.
| |
U |
V |
| Before |
1 u |
3 u |
| Change |
+ 2.6 |
+ 0.5 |
| After |
1 u + 2.6 |
3 u + 0.5 |
Both pails have the same volume of water in the end.
3 u + 0.5 = 1 u + 2.6
3 u - 1 u = 2.6 - 0.5
2 u = 2.1
1 u = 2.1 ÷ 2 = 1.05
Volume of water in Pail V at first
= 3 u
= 3 x 1.05
= 3.15 ℓ
Answer(s): 3.15 ℓ
