To me, the images are symbolic and communicate a clear intent, leading to an answer of 54kg. But if you're looking to be duplicitous about it then torque and the varying length of the lever make it unsolvable.

2x = 18
x = 9

5x + y = 72
5(9) + y = 72
45 + y = 72
y = 27

2y = ???
2(27) = 54

u impressed?

Pretty much how I worked it out too, and how the math problem leads you to work it out. So either that is the correct answer or there is some trick in which they purposely mislead you to solve it that way.

Is it just me or is the second balance slightly heavier on the left side?
