Question 1173660
.
Three partners Otieno , Ouma and Makotsi decide to start an export business together. 
If Otieno contributes sh 20000 for 9 months, Ouma contributes sh 25000 for 6 months and Makotsi contributes sh 35000 for 4 months,
find their share in profits of sh 1310000.
~~~~~~~~~~~~~~



<pre>
Otieno's  money contribution to the profit is proportional to the product (sh 20000 * 8 months) = 160000 (sh*month).


Ouma's    money contribution to the profit is proportional to the product (sh 25000 * 6 months) = 150000 (sh*month).


Macotsi's money contribution to the profit is proportional to the product (sh 35000 * 4 months) = 140000 (sh*month).


    ( the proportionality coefficient is the "interest rate" , obviously ).


Therefore, according to the common sense,  the total profit of sh 1310000 shoud be divided in proportion

    160000 : 150000 : 140000 = 16 : 15 : 14.


The number of equal parts is  16 + 15 + 14 = 45.


The parts to share the profit for each participant are:


    Otieno  :  sh  {{{(16/45)*1310000}}},

    Ouma    :  sh  {{{(15/45)*1310000}}},

    Makotsi :  sh  {{{(14/45)*1310000}}}.    


To get the numbers, use your calculator.
