In a 120 litre of solution of Acid and water, acid is 75%. A person takes out 20 litres of this solution and added 16.2 litres of acid and 3.8 litres of water in the remaining solution. What is the percentage of water in the final solution?
Answer and explanation
Correct answer B
The correct choice is: “24”
Initially: acid 90 L, water 30 L. Removing 20 L of solution (75% acid) leaves 100 L with 75 L acid and 25 L water.
After adding 16.2 L acid and 3.8 L water: total 120 L, water 25 + 3.8 = 28.8 L.
Water % = 28.8 ÷ 120 × 100 = 24%.
