Answer:
Option (b) $30,000
Explanation:
Data provided in the question:
shares of common stock issued @ $7 per share = 10,000
shares of common stock issued @ $8 per share = 20,000
Net income = $100,000
Dividend paid = $50,000
Number of treasury stocks purchased = 3,000
Price per stock of treasury stocks = $10
Now,
The balance in the Treasury Stock account at the end of 2021
= Number of treasury stocks purchased × Price per stock of treasury stocks
= 3,000 × $10
= $30,000
Hence,
Option (b) $30,000
