Answer:
a. Investment in Stain reported by paint would be $142,200 which is the fair value of common stock issued.
b. Fair value of common stock $142,200
Add: Fair value of non controlling interest $94,800
Less: Fair value of assets - Fair value of liabilities $208,000
(Assets - Liabilities) ($304,000 - $96,000)
Goodwill $29,000
c. Non-controlling Interest = 40% of [Fair value of common stock + Fair value of non controlling interest]
Non-controlling Interest = 40% of [$142,200 + $94,800]
Non-controlling Interest = 40% of $237,000
Non-controlling Interest = $94,800
