Question

A mixture of 120 liters of wine and water contains 20% water. How much more water should be added so that water becomes 25% of the new mixture?

• A. 20 litres
• B. 10 litres
• C. 8 litres
• D. 12 litres
• E. None of the above

Answer 1

The correct option is C 8 litres

Quantity of water in the mixture initially = 20% of 120 litres = 24 litres Let the quantity of water added be x. Then, $\frac{24+x}{120+x}=0.25$ Solving, we get x = 8 litres
