If any amount is distributed among A ,B and C so that the part of A is doubled that of the part of B and part of b is 6 time the part of C .Find the ratio among their parts.  Choose the correct choice from the following options:
A) 1:2:4
B) 1:4:1
C) 8:4:1
D) 12:6:1
E) 4:3:2
By the assumptions as mentioned we have A=2B and B=6C. So A=2(6C) and we get A=12C. We have, therefore, A:B:C = 12C:6C:C. By cancelling the ratio with C we have 12:6:1. The answer is, therefore, 12:6:1.
