Question: A and B start a business by investing Tk 20,000 and Tk 30,000 respectively. After one year, the profit is Tk 10,000. What is A's share of the profit?

Solution:
A and B start a business by investing Tk 20,000 and Tk 30,000 respectively.
→ Investment ratio = 20,000 : 30,000 = 2 : 3

→ After one year, Profit = Tk 10,000
→ A's share = (2/5) × 10,000 = Tk 4,000
