Since Vc is given, Assume β is 100 to get Ic, then β = Ic/Ib.

Use kvl: Vcc-RbIb-Vbe=0.
12V-226k(I) - 0.7V = 0, R = 50microA.
12V-226k(I) - 0.7V = 0, R = 50microA.

@Radhika,
Also 0.7 is general cut in voltage for silicon.

I have find that Ib =0.01. Then I can't go anywhere.

(12v - 0.7v)/226000 = 50uA.
@Radhika is right.
@Radhika is right.
