Divya has 1500 coins which are in the combination of gold and silver in the ratio of 5 ∶ 7. She distributed the silver coins among his three sons Nimesh, Monil and Gaurav in the ratio of 7 ∶ 12 ∶ 6. If Gaurav and Monil combined 60% of their silver coins and made jewelry from it and sell the remaining silver coins at Rs. 500 per coin, then the amount earned from selling of silver coin was distributed between Monil and Gaurav in the ratio of 12 ∶ 13. Find the difference between the amount earned by Gaurav and Monil from the silver coin transaction.
