Answer:
Common Stock 30%
Step-by-step explanation:
a common size balance sheet means to express each value of the balance sheet as a percentage of total assets.
as total liabilities and stockholders' equity is 2,000
From the accounting equation
Assets = Liabilities + Equity
we get that total asset is also 2,000
now we express common stock based on total assets:
600 / 2000 x 100 = 30%
