Answer:

Basically this depends on the type of cell division the cell undergoes.

if the cell undergoes reduction division of meiosis(n) the chromosome number will be reduced to 20 so the centromere will be 20, However if the cell undergoes multiplication division of mitosis,(2n) the centromere will be 40, since the chromosomes number will increases and sister chromatids holding the chromosomes are held at centro mere.
