Seriously, he burned down the store to get the insurance money of 50lakh, which is pretty obvious that lalaji will have to share with Alka's husband so Lalaji will get only 25 lakhs, in that he needs money for his operation, and the rest needs to be divided equally with Kasturi and her sisters. So anway he won't get much. But if he had waited for sometime and seen wht happens, then maybe Alka wud have been able to sell the shop and they wud have got 1crore, which she wud have had to share with Lalaji as he is 50% partner in it. So after all the sharing and operations, Girish wud have got double the money he wud have got if he had married Kasturi(which I highly doubt will happen, as Robbie has realized he loves Kasturi and he won't give up without a fight😳), don't u think so???
