Hi MikeMl,
I agree that with a real transistor an iterative solution would be required. The value for the hfe of the transistors quoted by the OP (443.3) is higher than the maximum value of 300 shown on the data sheet that I have. Also the value of hfe varies with the collector current so the method I used would not work with a real transistor. I don't see the point of this exercise as the result is so dependent on the hfe value which has quite a wide spread for any particular type of transistor.
