A tank in a Kolkata laboratory contains a solution of salt and water in the ratio 5:3. If 16 litres of water is added, the ratio becomes 5:4. Find the original quantity of solution.
Show answer & explanation
Correct answer: B
Explanation
Salt: Water = 5: 3, Water added = 16 liters, new ratio = 5: 4
Initial Salt = 5x, Water = 3x
New Water = 3x + 16
5x / (3x + 16) = 5 / 4
5x × 4 = 5 × (3x + 16)
20x = 15x + 80
5x = 80
x = 16
Total initial quantity = 5x + 3x = 8x = 8 × 16 = 128 liters
