Question: Sayed started a software business by investing Tk. 20000. After six months, Rafi joined him with a capital of Tk. 30000. After 3 years, they earned a profit of Tk. 13950. What was Sayed’s share in the profit?

Solution:
Ratio of capitals of Sayed and Rafi
= (20000 × 36) : (30000 × 30)
= 720000 : 900000
= 4 : 5.

Sayed’s share is = Tk. (13950 × 4)/9 = Tk. 6200.
