Had there been no friction, the monkey would have slipped down the moment it tries to pull the rope. Therefore, frictional force acts upward to prevent this.

mg-f = ma

=>f= m(g-a)

Since the monkey''s hands would slip downward if there was no friction, friction will act upwards to prevent this from happening.

 

mg-f=ma

f=m(g-a)
