Answer:
The total number of winners is 17.
Explanation:
Let's assume that the number of winners is "x". Then the number of participants who did not win is "45 - x".
The amount of money awarded to the winners is 1000x rupees.
The amount of money awarded to the participants who did not win is 200(45 - x) rupees.
According to the question, the total amount of prize money distributed is 22600 rupees. So we can write:

Simplifying this equation:



Therefore, the total number of winners is 17.
