Question

on. 2. Lake Don Juan in Antarctica is believed to be the saltiest body of water on earth. The lake water is approximately 40% salt. If you collected 125 liters of water from the lake, how many liters of salt would it contain?

Answer 1

Determine the litre of salt in lake water.

$\begin{gathered} \frac{40}{100}\times125=\frac{4}{10}\times125 \\ =\frac{500}{10} \\ =50 \end{gathered}$

So lake water has 50 litres of salt.
