Question

question 7 with ful process

Answer 1

Let a be 2x b be 3x c be 4x

A/b 2/3

B/c 3/4

C/a 2

2/3:3/4:2 multiply by 12

8:9:24

Answer 2

A : B : C = 2 : 3 : 4

Define x:

Let x be the constant ratio

A : B : C = 2x : 3x : 4x

Find A/B:

A/B  = 2x/3x = 2/3

Find B/C:

B/C = 3x/4x = 3/4

Find C/A:

C/A = 4x/2x = 2x

Find A/B : B/C : C/A

A/B : B/C : C/A = 2/3 : 3/4 : 2

Multiply by 12 through:

A/B : B/C : C/A = 8 : 9 : 24

Answer: (D) 8 : 9 : 24
