To estimate the number of foxes in an area, a researcher conducted a mark-recapture survey. In the first survey, he caught and marked N number of foxes. In his second survey a week later, he caught 120 foxes of which 90 were unmarked (recaptures). If you are told that the actual number of foxes in this area is 400, what is value of N in this area?
