What is wrong with this premise?

Here's an analogy.

10 mathematicians have a very complex equation, and they are trying to determine its solution; or whether indeed it can be solved at all. 9 of them are working really hard at it, but at the end of the first day, they still haven't cracked it. The 10th mathematician instead says the answer is 5.7, because at least that's an answer.

The next day, the 9 mathematicians continue to work hard, still don't get an answer. The 10th one does no work, because he already has an answer, 5.7 and he stick to it. He sees no point changing his answer, because the other 9 don't even have any answer.

Weeks pass...

Scenario (a)

Finally there is a breakthrough, the 9 mathematicians crack the equation and find that the answer is 92. The 10th one had been wrong all along, and had got no closer to the real answer.

Scenario (b)

After years of study, the 9 mathematicians eventually die without finding the answer to the equation, but their work is available for future generations. The 10th one sticks to his answer of 5.7, and passes this on to his children. They stick to this answer also, do don't do any work in trying to solve the equation.
