Ответ:
£78
Step-by-step explanation:
Given:
£130 is divided between Dan, David & Mark so that Dan gets twice as much as David, and David gets three times as much as Mark.
To find: How much does Dan get?
Solution:
Let D represents Dan, V represents David and M represents Mark.
Now we have given that Dan gets twice as much as David:
D = 2V (i)
David gets three times as much as Mark
V = 3M (ii)
The total sum of money is D + V + M = 130 (iii)
Putting (i), (ii) in (iii), we get:
2V + V + V/3 = 130
6V + 3V + V = 390
10V = 390
V = 39
Putting the value of V in (i), we get:
D = 2(39)
D = £78
Therefore, Dan gets £78
