Full explain this question and text typing work only thanks

We are trying to size the sub-lists in MOM algorithm. We want the guaranteed number of
elements in the list that are less than the generated pivot to be at least 40 percent of n. Assume
that n ≥ 9, the size of a sub-lists is an odd number, and n is a multiple of the size of the
sub-lists. Is this possible? If it is, what would be the maximum size of the sub-lists? Show
your work and justify your answer.
