Answer» The FIRST CARAVAN left half of the water. The second caravan left \BEGIN{lgathered}\frac{2}{3} \times \frac{1}{2} = \frac{1}{3} \\ \frac{3}{4} \times \frac{1}{3} = \frac{1}{4}\end{lgathered}32×21=3143×31=41of the water. Continuing the pattern, the 20th caravan LEAVES \frac{1}{21}211 or 50 m3 of water.
