WHY TF IS THE ANSWER NOT 9 ??
c=cv +r/1-j then to calculate j i assumed the process to be a random pv ^j then differentiated it to get the slope -jp/v then equated it with the slope of the given graph which is po(n-3)/4vo from this j comes out to be =3-n/12 on putting it in the eq i get n =9 what am i doing wrong here pls someone explain
