Question

if a:b=2:3,b:c=4:5,C:d=5:3 then find a:b:c:d.?​

Answer 1

Answer:

a:b:c:d is 2:3:4:5:5:3

Answer 2

A:B = 2:3

A = 2x, B = 3x

B:C = 4:5

B = 4x, C = 5x

A:B = 8x : 12x

B:C = 12x : 15x

A:B:C = 8x : 12x : 15x

Now,

C:D = 5:3

C = 5x, D = 3x

A:B:C = 24x : 36x : 15x

C:D = 15x : 3x

Therefore,

A:B:C:D = 24 : 36 : 15 : 3
