Answer:
C) personally have to contribute an additional $6,000
Step-by-step explanation:
X's capital balance = $90,000.
Y's capital balance = $60,000.
Z's capital balance = $30,000.
The partnership lost $120,000 which must be covered proportionally by the partners:
X has to cover 35% of the losses = $60,000
Y has to cover 35% of the losses = $40,000
Z has to cover 30% of the losses = $36,000
Since Z's capital balance is only $30,000, he owes the partnership $6,000 because his proportional losses were larger than his capital balance = $36,000 - $30,000 = $6,000
