# Help to calculate the collector current

Above circuit is taken from a book. It uses an NPN and a PNP transistor combination. In saturation, the author's answer to the Q2's collector current is 4.4mA and claims only 0.6mA of it comes from R3.

When I try to calculate this I get different answer. Apparently something wrong with my way here:

When Q2 is saturated I follow the following logic:

1-)The current comes down to Q2's qround through R3 and R2 resistors is: 15V/4.3k

2-)The current comes through emitter-base of Q3 is: (15V-0.6V)/3.3k

note: here 0.6 is the voltage in emitter-base junction in saturation

3-)The total collector current is the some of above two currents which is way above the author's answer

How can I analyse this circuit to find Ic of Q2? Whats wrong with my assumption?
