After reading this post, I think that it is written INCORRECTLY, and in this form DOES NOT represent any Math problem,
To become a Math problem, it must be totally re-written.
The original text is GIBBERISH in its purest form, and there is nothing to discuss around it.
Its only destination is to be thrown into the GARBAGE BOX (and wash the hands after that (!) )
Also, do not consider the post by @MathLover1 as something reasonable.
It is of the same degree of inadequacy, as the given formulation itself.
