Answer:
Consider the following calculations
Explanation:
Value of levered firm = Value of unlevered firm + debt*tax rate
As tax rate = 0
Value of levered firm = Value of unlevered firm =100m
Levered cost of equity = Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
Levered cost of equity = 11+0.5*(11-5)*(1-0)
Levered cost of equity = 14
