Pulley system of 2 fixed pulleys and 2 movable pulleys lift a rock that has 300N weight a constant speed. If effort used to lift rock is 100 N, what is the mechanical advantage of the system? 1/3, 3/4,3, or 6? I think 3.

Count the number of parallel attached to the lowest pulley. Thats the mechanical advantage

The 3 is true because the Mechanical advantage Formula is that the R/E means 300/100 = 3 . it is so easy .
