A king asks a learned man to visit his palace. The man says I will come any day next month. But give me gold in gms equal to the date on which I come. The king asks the jeweler to make rings of 1 to 31 gms. The jeweler was smart and makes only 5 rings. What are the weights of those rings?

The jeweler was smart enough!
He didn't make 31 rings with that date's grams for the learner but instead he wisely only made five rings of 1,2,4,8 and 16 grams so that you can add up these grams to get the total equal to that date.
For instance, if the learner visits on 31st then the king can give him rings of 1,2,4 and 16 to add up to 31.
That's all

The smart jeweller makes five rings of 1gm, 2gm, 4gm, 8gm and 16 gm. Now he can get any weight between 1 to 31 adding these five rings
