  1.  
    • Calculate the amount of money Kimani contributed. (2 marks)  
    • Find the ratio of the contributions by the three partners. (2 marks)   
  2. The money earned a compound interest at a rate of 8% per annum. After 3 years, the  partners withdrew the interest and donated 10% to a charitable organisation. The partners then shared the remainder in the ratio of their contributions.

  1. Ko :  Ki : At
    0.2: 0.3: 0.5
    Ki = 30 % of 1,750,000
    =Ksh. 525,000

    2:3:5
  2. A =PRnwhere R = 1+r
    =1750000(1.083)
    =2204496
    Shared amount=90% × 2204496
                              =1984046.4
    Kosgei=0.2 ×1984046.4
                  =Ksh. 396809
    Kimani=0.3 ×1984046.4
                       =Ksh. 595214
    Atieno=0.5 x1984046.4
                      =Ksh. 992023
