How is the zakat calculated for joint money and livestock left for trade and care in exchange for half the produce?

If trade money reaches the nisab (definition) and a year passes over it, its zakat (definition) is obligatory, which is a quarter of a tenth. As for sheep, if they reach forty and a year passes over them, one sheep is obligatory therein, and the amount increases with the increase in number, according to the details mentioned in the fatwa (definition). Sheep are considered mixed, and no distinction is made between them when giving out zakat.
