1 kg: put 2kg and 5kg on one side. On other side put the newapapers and 6 kg on a balance. 2 + 5 kg will give you 7 kg. And other side we have put 6kg and newspapers. If the the balance is equals, it means we have placed 1kg of newspapers (1 + 6kg = 7kg).
3kg: In the similar way, put 2kg and 6kg on one side and 5kg and newspapers on the other. 2 + 6 gives us 8kg. If the balance is equal, it means we have placed 3kg of newspapers (3 + 5kg = 8kg).
4kg: Put 5kg and 6kg on one side. And on the ither put another 5kg, 2kg and newspapers. 5 + 6 will give us 11kg. On the other side it is 2 + 5 + newspapers, which is nothing but 7kg + newspapers. If the balance equals it means, we have placed 4kg of newspapers (4 + 7kg = 11kg).
7kg: Put 2kg and 5kg on one side and newspapers on the other side. If the balance equals, it means we have placed 7kg of newspapers.
