প্রশ্ন: Arif, Kamal and Shajib invested Tk.8000, Tk.4000 and Tk.8000 respectively in a business. Arif left after six months. If after eight months, there was a gain of Tk.4005, then what will be the share of Kamal in this gain?

সমাধান:
Arif : Kamal : Shajib = (8000 x 6) : (4000 x 8) : (8000 x 8)
= 48 : 32 : 64
= 3 : 2 : 4

∴ Kamal's share = {4005 x (2/9)}
= 890 Taka
