Ravi used to live in a village that was next to the forest. One day he crossed paths with a genie. The genie was in a generous mood and granted Ravi one wish. Ravi, thinking it was a joke, wished for a 100 grams of gold. The genie agreed and behold! Ravi had a kilo of gold. Shocked and feeling upset that he asked for so little, Ravi requested the genie if he could ask for another wish. The genie agreed but only on one condition. The genie would come back next month on any date and Ravi would need to present him with gold rings. However, the gold rings had to be the same weight as the date on which he arrived. This means that if the genie came on the 20th, he would need 20 grams of gold. What did Ravi do next?

Ravi could make gold rings of different weights,
mainly of 1 gram, 2 grams, 4 grams, 8 grams and 16 grams.
With these gold rings he can give the same amount of gold equal to the date of that Month.
For example, if on 20th then 16+4
if on 31st then 1+2+4+8+16
And so on...
