The cost price of 1,000 shirt is 9,000 Tk.
∴ The cost price of 1 shirt is
Sales in 1st month = (75% of 1,000) = 750 Shirts
∴ Selling price of 750 shirt in 1st month
∴ Remaining shirt = 1,000-750 = 250
∴ 50% of remaining shirt after 1st month's sale
Then selling price is
∴ Total sales = 12,150+ 1,350 = 13,500 Tk.
∴ Gross Income = 13,500 Tk.
