Answer:
There are 20 R100 notes and 80 R50 notes.
Explanation:
Let's call the number of R100 notes "x" and the number of R50 notes "4x" (since there are 4 times as many R50 notes as R100 notes).
We can set up an equation to represent the total value of the notes:
100x + 50(4x) = 6000
Simplifying:
100x + 200x = 6000
300x = 6000
x = 20
So there are 20 R100 notes and 4 times as many R50 notes:
4x = 4(20) = 80
Therefore, there are 20 R100 notes and 80 R50 notes.
