Given:
Actual salt water = 4 litres (with 15% salt in it)
Spilled out = 1.5 litres (with 15% salt in it)
Remaining is = 2.5 litres (with 15% salt in it)
Now filled with pure water = 2.5 litres (with 0% salt)
Solution:
So, new quantity = 5 litres
Water quantity doubles and
hence, salt must dilute into half
Therefore, salt % is 7.5% |
