I got #940#

Explanation:

Let us call the total number of sudents #x#; this corresponds to #100%# or the total number of stdents.
We can now relate the quantities with the percents as:
#(100%)/(40%)=x/376#
i.e. in "percent world" you have #40# out of #100# students while the corresponding in "students world" will be #376# out o#x# (the total).
Rearranging:
#x=(100cancel(%))/(40cancel(%))*376=940# students in total.

Hope it helps!
