62

Explanation:

Easy way:
#155/2=31# Then take #2*31# to get the number of nurses which is #61#

Harder way:
#2/5*x/155# Then cross multiply. You should get #5x=310#. Then to get #x# by itself, divide both sides by #5# to get #x=62# and that's the number of nurses on duty if there were #155# patients in the hospital.
