Solution

The number of chromosomes in the endosperm of a plant is typically triploid, or three times the haploid number of chromosomes.

In this case, the male plant contributes one set of chromosomes (n=20) and the female plant contributes two sets of chromosomes (n=30).

So, if they are artificially hybridised, the number of chromosomes in the endosperm would be 20 (from male) + 30*2 (from female) = 80 chromosomes.
