A 50-liter solution contains acid and water in the ratio 3 : 2. How much water must be added to make the ratio 1 : 1?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10 L.
Acid-water ratio = 3 : 2
Acid = (3/5) × 50 = 30 L
Water = (2/5) × 50 = 20L
Let water added = x L
(20 + x) = 30
⇒ x = 30 - 20 = 10 L
