Question 1195130
<br>
The ratio of their contributions is 250:100:50 = 5:2:1.  So the fractions of the total that each of them provided is<br>
George: 5/8
Jenna: 2/8
Doreen: 1/8<br>
Dividing the profit of R160000 into 8 equal parts makes each part R20000.  So the profit for each of the three is<br>
George: 5*R20000 = R100000
Jenna: 2*R20000 = R40000
Doreen: 1*R20000 = R20000<br>
