<PRE><B>Question 816844</B>
w = weak solution volume
s = strong solution volume
---
alcohol in the mixed solution:
0.25w + 0.60s = 0.53*40
---
total volume in the mixed solution:
w + s = 40
w = 40 - s
---
0.25w + 0.60s = 0.53*40
0.25(40 - s) + 0.60s = 21.2
10 - 0.25s + 0.60s = 21.2
0.35s = 11.2
---
Answer:
s = 32 liters
w = 8 liters
