Ali puts sh 5000 for 1 year and Alex puts sh

8000 for 9 months to start a business.They
shared their profit at the end of the year.Ally
share comes to sh 2000.What will be Alex's
share? please I need your help*

the answer is 2400/= hw can I arrive that answer

Their share of the profit should be proportional to the amount of their investment

Total investment = 13000
Alex's share is 8000/13000 = 8/13
Ali's share is 5/13

So 5/8 = 2000/x , assuming Ali and Ally are the same person
5x = 16000
x = 3200

check:
2000 : 3200
= 5 : 8
