एक बार एक दामाद अपने ससुराल फोन करता है कि, मैं अगले महीने ससुराल आऊंगा। पर मैं जिस तारीख को आऊंगा मुझे उतने ग्राम सोना चाहिए। ससुर तुरंत अपने पहचान के सुनार के पास गया और बोला क़ि वो 1 से 31 ग्राम तक की अंगूठी तैयार करके रखे, जिस तारीख को दामाद आये उतने ग्राम वाली अंगूठी मैं ले जाऊंगा। पर उस सुनार ने सिर्फ 5 अंगूठियां बनायीं जिनसे किसी भी तारिख की ज़रूरत पूरी हो जायेगी। सुनार ने कितने कितने ग्राम की अंगूठियां बनायीं और कुल कितना सोना इसमें लगा...? सही उत्तर बतायें।

Thanks for the question!!!
If son-in-law arrives on 3rd day, he can get ring with 1 & 2 grams.
If son-in-law arrives on 15th day, he will be given ring with 1, 2, 4, 8 grams.
If son-in-law visits on 30th day, he will get ring with 2, 4, 8, 16 grams.
So,rings with weight 1, 2, 4, 8, 16 grams will be made and the combination of these five numbers will give all date range from 1-31 of any month.
Following are the date-wise combination of rings--
1 = 1
2 = 2
3 = 2+1
4 = 4
5 = 4+1
6 = 4+2
7 = 4+2+1
8 = 8
9 = 8+1
10 = 8+2
11 = 8+2+1
12 = 8+4
13 = 8+4+1
14 = 8+4+2
15 = 8+4+2+1
16 = 16
17 = 16+1
18 = 16+2
19 = 16+2+1
20 = 16+4
21 = 16+4+1
22 = 16+4+2
23 = 16+4+2+1
24 = 16+8
25 = 16+8+1
26 = 16+8+2
27 = 16+8+2+1
28 = 16+8+4
29 = 16+8+4+1
30 = 16+8+4+2
31 = 16+8+4+2+1
Therefore, the goldsmith made five rings of 1,2,4,8,16 grams, and counted 31 grams of gold in it.
It is a very simple riddle that can be easily solved.
Hope it is helpful to you and solves your query too!!!!
