Answer:
$90,000
Step-by-step explanation:
We are assuming that the $210,000 paid for 70% of Pumpkin Corporation represents a fair value for their stock. The non-controlling interest is 30% of the company's stocks and we can use the value paid to determine the value of the non-controlling interest.
Non-controlling interest = ($210,000 / 70) * 30 = $90,000
