cost of capital

thank you so much sir , doubt has been cleared for kd(1-t)
don’t get me wrong i watched all lectures in prior months in order to practice now the revision kit questions , when i get stuck i use your notes but that question was difficult to find , when you told me that it is in the notes then i refered and hence doubt is cleared
sorry for your time , i thought all the notes could be fresh in my mind all the time
