Sagot :
Answer:
- 30 liters
Step-by-step explanation:
When you make a such solution the alcohol content remains same. Let the added volume is x.
Then we have:
- x*60/100 + 60*30/100 = (x + 60)*40/100
- 0.6x + 18 = 0.4x + 24
- 0.6x - 0.4x = 24 - 18
- 0.2x = 6
- x = 6/0.2
- x = 30
The added volume is 30 liters
Answer:
30 Liters
Step-by-step explanation:
A × 60% + 60 × 30% = (A + 60) × 40%
60%A + 18 = 40%A + 24
60%A - 40%A = 24 - 18
20%A = 6
A = 6 : 20%
A = 30
