Answer: A) 10 liters Explanation: 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
