Given,
A:B=2:3 ________(i)
B:C=4:5 ________(ii)
C:D=5:8 ________(iii)
Let in eq.(i)
A=2x and B=3x
Now, multiplying by 4 in eq.(i)
A=8x and B=12x
And, multiplying by 3 in eq.(ii)
B=12x and C=15x
So, A:B:C=8x:12x:15x
Again, multiplying by 3 in eq.(iii)
C=15x and D=24x
Therefore,
A:B:C:D=8x:12x:15x:24x
A:B:C:D=8:12:15:24
Thus, A:D=16:24
