Tank K has five times as much water as Tank J. If Andy adds 0.3 ℓ of water to Tank K and 1.7 ℓ of water to Tank J, both tanks will have the same volume of water. Find the volume of water in Tank K at first.

J |
K |
| Before |
1 u |
5 u |
| Change |
+ 1.7 |
+ 0.3 |
| After |
1 u + 1.7 |
5 u + 0.3 |
Both tanks have the same volume of water in the end.
5 u + 0.3 = 1 u + 1.7
5 u - 1 u = 1.7 - 0.3
4 u = 1.4
1 u = 1.4 ÷ 4 = 0.35
Volume of water in Tank K at first
= 5 u
= 5 x 0.35
= 1.75 ℓ
Answer(s): 1.75 ℓ
