God gave him one stone and said, "Find out the value of this stone, but don't sell it."
The man took the stone to an Orange Seller and asked him what it's cost would be.
The Orange Seller saw the shiny stone and said, "You can take 12 oranges and give me the stone."
The man apologized and said that the God has asked him not to sell it.
He went ahead and found a vegetable seller. "What could be the value of this stone?" he asked the vegetable seller. The seller saw the shiny stone and said, "Take one sack of potatoes and give me the stone."
The man again apologized and said he can't sell it.
Further ahead, he went into a jewellery shop and asked the value of the stone.
The jeweler saw the stone under a lens and said, "I'll give you 50 Lakhs for this stone." When the man shook his head, the jeweler said, "Alright, alright, take 2 crores, but give me the stone."
The man explained that he can't sell the stone. Further ahead, the man saw a precious stone's shop and asked the seller the value of this stone.
