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