Hi,
My mid-term quiz is next week. I have tried to solve this question but I'm stuck on Qn 4 Part H. Any hints?? The image at imgur is much clearer.

I don't know what that book defines as applicable to the "voltage divider rule".. I always thought that a load not less that 10 times the resistance of the divider resistor was recommended. The load is 3k times beta = 300k . Therefore, R2 should not be greater than 300k/10 = 30K. To keep the same ratio, R1 should be one and one half times greater or 45k .
