Answer: 4.8 liters
Step-by-step explanation:
Let x liter of water is added with y liter of 25% beach solution.
Thus, According to the question,
x + y = 12 -------(1)
0% of x + 25 % of y = 15 % of 12
25 % of y = 15% of 12



Put this value in equation (1),
We get,




Therefore, the quantity of water = 
And, the quantity of 25% bleach solution = 
Answer:
