A sum of money is distributed among A, B and C in the ratio 8 : 4 : 3. If A divides his part between D and E in the ratio 9 : 7, then what is the ratio of the share of C to that of D?

2 : 3

 A  :  B  :  C 

 8  :  4  :  3

Multiplying by 2,

16 :  8  :  6

Now, A's part is divided among D and E in the ratio = 9 : 7

Ratio of C and D = 6 : 9 = 2: 3
