Question: Monir started a business investing Tk. 9000. After five months, Amir joined with a capital of Tk. 8000. If at the end of the year, they earn a profit of Tk. 6970, then what will be the share of Amir in the profit?

Solution:
Now as per the question,
Monir invested for 12 months
and Amir invested for (12 - 5) = 7 months.

So
Monir : Amir = (9000 × 12) : (8000 × 7)
= 108000 : 56000
= 108 : 56
= 27 : 14

Amir Ratio in profit will be = 6970 × (14/41)
= Tk. 2380
