Answer 1

Solve it Using maths percentage

Answer 2

30 liters is an appropriate answer.

Given:

• The combination of wine and water = 70 liters.

• Initial water concentration = 10%.
• Calculations:
• Amount of water in 70 liter of combination = 10% of 70 = 7 liters.
• Let x liters of water is added to the combination.
• According to question, 7 + x = 37/100 x (70 + x)  
• 100(7 + x) = 37 (70 + x)
• ⇒ -x = 189/63 = 30  

Therefore, x = 30 liters.
