You are provided with a 230 V / 50 Hz ac supply, a 6-0-6 centre-tapped transformer and a BJT of dc current gain 150. Biasing the transistor using a supply of 5.6 V (develop your own), (i) design an amplifier of voltage gain 200

i have designed could anyone correct me
design as follows
Av=200
Av=-gmRc
assuming ic =1mA
200=1*10^-3xRc/0.025
Rc=5Kohm
beta=ic/ib
ib=6.67uA
Vce=Vcc-IcRC=0.6
we take voltage divider ckt
SO assuming Rb as 6.8 kohm
vth=0.752
solving we get
so we get r1 as 52.4 kohm
r2as 7.14
re is not there

vbe is 0.68

can anyone correct me

We are not mind readers -- please provide a schematic for your design so that we know what you are talking about.
