Answer:
Total Amount of money = £4800
Step-by-step explanation:
Let the shares of Dan, Ellen and Fred be 4x, 7x and 9x respectively.
According to the given information:
Amount received by Ellen = Amount received by Dan + £720
7x = 4x+720
7x-4x=720
3x = 720
x = 720/3
x = £240
now,
4x = 4*240 = £960
7x = 7*240 = £1680
9x = 9*240 = £2160
Total Amount = £960 + £1680 + £2160
Total Amount = £4800
