The capital contributions of A, B, and C are in the ratio \[ \cfrac{1}{x} : \cfrac{1}{y} : \cfrac{1}{z} \] This can be rewritten as: \[ = yz : zx : xy = \cfrac{yz}{xy + yz + zx} : \cfrac{zx}{xy + yz + zx} : \cfrac{xy}{xy + yz + zx} \] Therefore, C’s share of the loss \[ = z \times \cfrac{xy}{xy + yz + zx} = \cfrac{xyz}{xy + yz + zx} \text{ taka} \]
