Answer: Option (b) is correct.
Explanation:
Given that,
Net income = $160,000
Dividend paid to common stockholder = $50,000
Dividend paid to preferred stockholders = $20,000
common stockholders' equity at the beginning = $870,000
common stockholders' equity at the end = $1,130,000
[tex]Average\ common\ stockholders\ equity=\frac{Beginning\ Balance + Ending\ Balance}{2}[/tex]
[tex]Average\ common\ stockholders\ equity=\frac{870,000 + 1,130,000}{2}[/tex]
[tex]=\frac{2,000,000}{2}[/tex]
= 1,000,000
[tex]Return\ on\ common\ stockholders\ equity=\frac{Net\ income-preferred\ dividend}{Average\ common\ stockholders\ equity}[/tex]
[tex]Return\ on\ common\ stockholders\ equity=\frac{160,000-20,000}{1,000,000\ equity}[/tex]
= 14%
