After meiosis, how many chromosomes does each new gamete have if the original organism has 20?

Meiosis divides the number of chromosomes by half, forming haploid cells. The sperm and the egg are haploid cells and when they fuse during fertilisation, voila! you get back your diploid original.
The answer to your question would then be 10.

Half as many, so if your diploid number of chromosomes is 20, then after meiosis, each gamete will have 10.

If the original organism has twenty, there will be TEN in each cell after meiosis is complete (gametogenesis).
Humans have 46 chromosomes so the same process in us leaves our diploid cells (ie 23 pairs of chromosomes) in a haploid state (ie 23 unpaired chromosomes).

If the division is meiosis, then each new gamete will have half the original no of chrosomes.
In this case it is 10.

10, if the original organism has 20 chromosomes in total (if that is actually what you mean).
Just out of curiosity which species are you referring to?

10 of coarse.
