Q6.

imageIn the circuit shown, the identical transistors Q1Q_1 and Q2Q_2 are biased in the active region with β=120\beta = 120. The Zener diode is in the breakdown region with VZ=5V_Z = 5 V and IZ=25I_Z = 25 mA.

If IL=12I_L = 12 mA and VEB1=VEB2=0.7V_{EB1} = V_{EB2} = 0.7 V, then the values of R1R_1 and R2R_2 (in kΩ\Omega, rounded off to one decimal place) are ________, respectively.
