st: Randomly picking observations based on a certain condition

[Nikhil Srivastava <nikhil.del85@gmail.com>]

Hi,

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?

I would really appreciate any help in this regard. Thanks

Regards,
Nikhil Srivastava
