One fine day, while the bellringer was ringing his bells, the bishop approached him and said:
"O Bellringer, knowing your passion for mathematical problems, I have a puzzle to set thee. In my flock there are three persons whose ages added together are twice your age. The product of their ages is 2450. Please let me know their respective ages."

The next day the bellringer approached the bishop and said: "O Bishop, you did not give me sufficient information to solve the problem yesterday."

To which the bishop replied: "My apologies, o Bellringer. I had omitted to tell you that I am older than any of you."

With this information the bellringer was able to tell the bishop the solution to the problem.
