When fresh fish is dried it becomes one-third its weight. In one month they plan to dry $6000 kg$ of fresh fish. How much-dried fish will they get in a month?

Given:

Weight of a dried fish $= \frac{1}{3}$ initial weight 

Weight of the fish to be dried $= 6000kg$

To find: The amount of dried fish obtained in a month

The amount of obtained dried fish in one month

                                      $=$ The initial amount of fresh fish $\times \frac{1}{3}$

                                        $= 6000\times \frac{1}{3}kg$

                                        $=2000kg$

They will get $2000kg$ of dried fish in a month.

Hence, Option B is the Correct Answer.
