A = 5
B = 9
C = 18
D = 6
Try and error...
B = 9
C = 18
D = 6
Try and error...
A is multiple of 5, therefore
A = 5 10 15 20
B is greater than A,
Therefore A can't be 20,
A = 5 10 15
Ratio C : B = 2:1
B can't more than 10 as c will be more than 20.
Therefore, A = 5
And B = 6 7 8 9 10 as B greater than A.
½ D = ¹/6 C, ratio D:C = 2:6
D is not the smallest, D must be more than A (5)
D must be 6 so that C = 18 then B = 9 due to ratio B:C = 1:2
If D More than 7 or 8, C will be more than 20.
So,
A = 5
B = 9
C = 18
D = 6
Hope this helps
