Theory:

In their answers to the second question, some said that the people most necessary to the king were his councillors; others said, the priests. A few others chose the doctors. And yet others said that his soldiers were the most necessary.
 
To the third question, some said science. Others chose fighting, and yet others religious worship.
 
As the answers to his questions were so different, the king was not satisfied and gave no reward. Instead, he decided to seek the advice of a certain hermit, who was widely known for his wisdom.
Explanation:
  
For the second question (which people should he listen to/who are the most important people), the answers that the king received were:
 
  1. Councillors (members of the council)
  2. Priests
  3. Doctors
  4. Soldiers
For the third question (what is the most important thing to do), the answers got were:
  1. Science
  2. Fighting
  3. Religious worship
Since the king got all variety of answers, he was not satisfied at all. He was unable to give the reward to anyone. So he decided to meet a hermit (sage) who was famous for his wisdom.
