In March 2019, the data is following: Primary applicants : 1438 Secondary applicants : 1398 Total applications : 2836
If we subtract the primary and secondary applicants we get (1438 - 1398) 40 applicants. This means there are 40 single applicants because with the secondary applicants(1398) there has to be equal number of primary applicants (1398) associated with it. And the number of single applicants (40) will have no secondary applicants linked with it.Just for the simplicity lets keep 1:1 ratio for primary and secondary applicants for each case.Now, is it correct understanding that are only 40 single applicants in the month of March this year?
