Answer:
Ratio of Ed's share : Dave's share = 4 : 5
Step-by-step explanation:
Total amount shared = £720
Let us assume that Dave receives = £m
So, Chris's share = £90 + m
Also, Chris's share : Dave's Share = 7: 5
⇒
Here, solving for m , we get : 5(90 + m) = 7m
or, 450 + 5m = 7m
⇒ 2m = 450, ⇒ m = 225
So, Dave's Share = m = £225
Chris's share = £90 + m = 225 + 90 = £ 315
Hence, Ed's share = Total - ( sum of Dave's and Chris's share)
= 720 -( 315 + 225) = £180
So, ratio of Ed's share : Dave's share = £180 : £225
or, Ratio of Ed's share : Dave's share = 4: 5
