Answer: There are 3 quarts of concentrate and 9 quarts of water.
Step-by-step explanation:
Since we have given that
Ratio of number of quarts of water to number of quarts of concentrate is
3:1
Number of quarts of orange juice from concentrate and water = 12 quarts
So, the number of quarts of concentrate would be
[tex]\dfrac{1}{4}\times 12\\\\=\dfrac{12}{4}\\\\=3\ quarts[/tex]
the number of quarts of water would be
[tex]\dfrac{3}{4}\times 12\\\\=3\times 3\\\\=9\ quarts[/tex]
Hence, there are 3 quarts of concentrate and 9 quarts of water.
