A battery dealer incurs an expense of Rs. 150 for producing every battery.
He also incurs an additional expenditure of Rs. 30000, which is independent of the number of batteries produced.
If he is able to sell a battery during the season, he sell it for Rs.250.
If he fails to do so, he has to sell each battery for Rs. 100.
If he produces 1500 batteries, what is the number of batteries that he must sell during the season in order to break-even, given that he is able to sell all the batteries produced?
