Question 1175103
.


Unfortunately (or fortunately ?), this post DOES NOT provide all necessary input info to give a numerical answer.


Also, where I should "click to display that info" ?



In general, my feeling is that the problem is created by very weak "problems composer" and has educational value 

indistinguishable from zero (if not negative . . . ).


It is not able to inspire anyone to solve it.



THEREFORE, I think that it is mercifully that the problem has a lack of input data, making its solution IMPOSSIBLE.
