An organism has a haploid number of 20 what is the organisms diploid number

Explanation:

The number of chromosome sets in a diploid is just the double of number of chromosomes in its haploid. For instance, if a haploid has “n” number of chromosome set, then a diploid will have “2n” of chromosome sets.  

Here, the number of chromosome sets in haploid is equal to

Then the number of chromosome sets in diploid will be equal to  

Hence, the organisms diploid number is

weathering is the answer.
