ВЭФ 12 (Astrad VEF 12 Project) - including a transistor tutorial

So what's the problem? Well, any valve example would give current values with the load. Say, 50,000 R, a curve in milliamps and a voltage. For example -5 bias, 50,000 R load and, say, 0.002 amp. Plucking currents just from resistance and voltage without impedance values or a q bias quoted is unusual for voltage amplification.

Hi there NM, Marks question wasn't about voltage amplification, that's a separate subject, the question was about determining the DC voltages and currents in the circuit that was provided from the information shown in the circuit.

I suspect the question was designed to see if you had a good basic understanding of DC current flow and voltage drop in a resistive circuit and the voltage drop across the base/emitter junction of a transistor, I suspect that you do but you need to put things across in a logical, reasoned and presentable manner otherwise it gives the impression that you don't understand.
