Answer 2

Answer:

The correct answer for this question is (c) 18:24:30:35

Step-by-step explanation:

A:B=2:3 and B:C = 4:5

making common base for B

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

so A:B:C= 8:12:15…..(1)

now again C:D=6:7 let’s make common base for c now with proportion 1

A:B:C=16:24:30 and C:D=30:35

so we get A:B:C:D=16:24:30:35
