Given:
Total tip = £77.40
Paul, Colin and Brian share the tips in the ratio 2:3:4.
To find:
How much more does Brian get over Paul?
Solution:
Let the shares of Paul, Colin and Brian are 2x, 3x and 4x respectively.
[tex]2x+3x+4x=77.40[/tex]
[tex]9x=77.40[/tex]
[tex]x=\dfrac{77.40}{9}[/tex]
[tex]x=8.6[/tex]
Now, the different between Brian and Paul share is
[tex]Difference=4x-2x[/tex]
[tex]Difference=2x[/tex]
[tex]Difference=2(8.6)[/tex]
[tex]Difference=17.2[/tex]
Therefore, Brain get £17.2 much more over Paul.
