Question
A 16-liter salt solution contains 6% salt. If 4 liters
of water are evaporated by boiling the solution, what is the new percentage of salt in the remaining solution?Solution
Quantity of salt in the solution = 16 x 0.06 = 0.96 litres After evaporating, remaining quantity of salt solution = 16 - 4 = 12 litres Therefore, percentage of salt in the final solution = (0.96/12) x 100 = 8%
