The ratio of water and acid is 3 : 4. If 39 liters of acid is mixed in the solution then the ratio changed to 2 : 3. Find the ratio of water in initial and acid in final mixture.
Answer & explanation
Correct answer: option 3
Water : Acid
Initial → 3 : 4
Final → 2 : 3
Here if we add only acid in initial mixture, then ratio of water should be same. Therefore,
Water : Acid
Initial → 6 : 8
Final → 6 : 9
Required ratio = Intial water : Final acid = 6 : 9 = 2 : 3
