Since the object is at rest, the forces in the vertical direction must balance each other out. Thus, the weight of the object must be equal to the combined tension of the two ropes. 
Therefore, weight (W) = Tension in rope 1 + Tension in rope 2 
W = 25 lb + 31 lb 
W = 56 lb 
Thus, the weight of the suspended object is 56 lb.
