This doesn't strike me as a precise specification. Would you be satisfied with the first random sample of 100 from the whole that includes observations from each quintile? 

Why sample any way? Why divide into quintiles?

I have a dataset at the household level which contains the expenditure
details of a sample of households. The dataset also records the number
of adults within each household. I have divided this dataset into 5
quintiles based on the level of expenditure. Now I need to randomly
select a set of observations within each quintile so that the sum of
the adults for those observations comes to 100. Could somebody please
help me in writing a code for this part?
