Question: A, B, C started a business investing Tk. 250000, Tk. 300000, and Tk. 350000 respectively. Find the share of B, out of an annual profit of Tk. 187200.

Solution:
Given that,
A invests = Tk. 250000
B invests = Tk. 300000
C invests = Tk. 350000

∴ Ratio of investments = 250000 : 300000 : 350000
= 25 : 30 : 35
= 5 : 6 : 7.
Total profit = 187200.

Total ratio parts
= 5 + 6 + 7
= 18.

∴ B's share = (6/18) × 187200
= (1/3) × 187200
= Tk. 62400.
