Marks: +1, -0

If

1/ 2

of A

2/ 3

= of B

1 /3

= of C, then A : B : C is:

4 : 3 : 6
6 : 4 : 5
5 : 4 : 6
4 : 6 : 5

Solution:

1/ 2

of A

2/ 3

= of B

1 /3

= of C

A={2B}/3×2={4B}/3

B=C/3×3/2=C/2

Now the ratio of A : B : C

{4B}/3:C/2:C=4/3×C/2:C/2:C

={2C}/3:C/2:C=4C:4C:6C

Ratio of A : B : C is 4 : 3 : 6
