A container contains acid and water in the ratio of 5 : 4 respectively. 20% of the total is drawn off and replaced by water, Find the new ratio of water and acid now.
Answer & explanation
Correct answer: option 2
Acid : Water
5 : 4
Let the quantity of acid & water = 90 liters
20% of 90 is drawn off & replaced with water i.e. 18 liters
Acid drawn off = 18 × \(\frac{5}{9}\) = 10 liters
Water drawn off = 18 × \(\frac{4}{9}\) = 8 liters
Water : Acid
50 - 10 : 40 - 8 + 18
40 : 50
4 : 5
