Selecting an exact number of objects


I have 1500 surfaces in a surface component and I need to select 90 of them. The 90 Surfaces and the remaining 1410 surface are to be extruded at different heights. I used the random reduce component but I am not sure how to keep the surfaces that have been deleted so that I can extrude them. I also thought of cull pattern but I am not sure how to set an exact number of point to cull…

Any ideas? Thank you.

(There is not much in the rhino/grasshopper files but I attached them anyway)
