3.5.3.3 Why does Solve work in v9.0.1 but not in v10.3.1

http://mathematica.stackexchange.com/questions/107585/why-does-solve-work-in-v9-0-1-but-not-in-v10-3-1

 
I want to solve the following DE 
$$ P'=k(M-P)P, P[0]=53.08, P[50]=23.192, P[100]=76.212.$$ 
The Mathematica command is 
 
sol1 = DSolve[P'[t] == k (M - P[t]) P[t], P[t], t] 
 
P[t_] = sol1[[1,1,2]] 
 
sol2  ...
