12 landlords gift 12 lumps of gold each weighing 1kg. each to their king, one of whom used vacuum in each of his lump of gold which makes his lump of gold weigh less by 100 gms each. Now King orders PM to identify the culprit weighing once only. How?
 
This is a classic puzzle.

What ideas have you tried? How many lumps from each landlord might you weigh in the one weighing? What went wrong with your attempt?

Since this is a tricky puzzle I will give you a hint. PM get to choose as many gold lumps as desired but in the end only get to weigh once. Do not pick the same amount from each of the 12 landlords.
