newspaper company currently sells 20000 newspapers per day. When it sells one newspaper at ₹5, it makes a profit of ₹2 per paper. It is observed that if the selling price of a newspaper is increased by ₹xx, then the number of newspapers sold per day decreases by 2000xx. What should be the selling price per paper (in ₹) to obtain the maximum profit?

Overall profit = customer ( Selling Price - Cost Price )
Cost Price of one Newspaper = Selling Price - Profit on one Newspaper
= 5 - 2
Overall profit = 20000 ( 5 - 3 )
Selling is increased by x and newspapers sold decreased by 2000x
Overall Profit = (20000 - 200x ) ( (5 + x ) - 3 )
Overall Profit = (20000 - 200x ) ( (2 + x )
Because we have to maximize the profit , we have to find the max. value of the quardatic function
