Question

A mixture of 150 liters of wine and water contains 20% water. How much more water should be added so that water becomes 25% of the new mixture?

Options:

A . 10 liters

B . 20 liters

C . 40 liters

D . 30 liters

Answer: Option A

Number of liters of water in 125 liters of the mixture = 20% of 150 = 1/5 of 150 = 30 liters Let us Assume that another 'P' liters of water are added to the mixture to make water 25% of the new mixture. So, the total amount of water becomes (30 + P) and the total volume of the mixture becomes (150 + P) Thus, (30 + P) = 25% of (150 + P) Solving, we get P = 10 liters
