Concept:Goodwill is an intangible asset that arises when a buyer pays more for a business than the fair value of its identifiable net assets.Explanation:Identify all assets: Plant and Machinery =190,000, Motor Vehicle =170,000, Stock =60,000.Total assets =190,000+170,000+60,000=420,000.The business also has current liabilities of 50,000, so the net worth of the business is:Net assets =420,000−50,000=370,000.Goodwill is the difference between the purchase consideration and the net assets acquired:Goodwill =400,000−370,000=30,000.This 30,000 represents the amount paid for the reputation and earning power of the business beyond its physical assets.Answer:D. ₦30,000
