Answer:
£3250
Explanation:
ann : ben : cheryll
3 : 7 : 10
The difference between ben and ann in the ratio is 7 - 3 = 4
The real difference between ben and ann is £650.
The real numbers are in the ratio 3:7:10, but they are many times greater than 3, 7, and 10.
Introduce a variable in the ratio.
3x : 7x : 10x
The difference between ben and ann is 7x - 3x = 4x.
The real difference between ben and ann is £650.
Therefore,
4x = £650
x = 162.5
The total money in the ratio is 3x + 7x + 10x = 20x
20x = 20(162.5) = 3250
