1 L of water is added to 5 L of alcohol and water solution containing 40% alcohol strength. The strength of alcohol in the new solution will be?
Correct Answer: 331/3%
Explanation:
Quantity of alcohol in 5 L of solution = (40/100) x 5 = 2 L
Quantity of alcohol in 6 L of solution = 2 L
∴ Strength of alcohol in new solution = (2/6) x 100%
= 331/3%
