How many total quarts in the original mixture?

anonymous · Answer

20 quarts?

triciaal · Answer

20% of 20 = 4 quarts of red originally 
add 5 quarts now you have 9 quarts of red in the total mix of (20 + 5 ) 
as a percentage = 9/25* 100 = 36 %

triciaal · Answer

check  9/25 + 7/25 + 9/25 = 25/25
  red , yellow and water respectively
36% + 28% + 36% = 100%
