Since the stick by itself is unbalanced with the fulcrum off center, the weight must be placed on the short (40 cm) side. Let x be the distance of the 1 N weight from the fulcrum, measured toward the short end, in cm. The stick's weight acts at the center of mass at x = -10 cm
0.8*(-10) + 1*x = 0 at equilbrium
x = 8 cm
0.8*(-10) + 1*x = 0 at equilbrium
x = 8 cm

0.8*40-1x=0
x=32cm
