Question 891845
Three students Phumelo, Ivan and John painted a room together.
 They spent 4 hours, 3hours and 1hour respectively on the task.
 They earned R400 in total. For the job. How much should each of them receive?
:
We can say the ratio is: 4:3:1
let x = the multiplier
then
4x = P's share
3x = I's share
x = J's share
:
4x + 3x + x = 400
8x = 400
x = 50 is the multiplier
then
4(50) = $200 is P's share
3(50  = $150 is I's
$50 is J's share
