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 5 time the part of C .Find the ratio among their parts.	Choose the correct choice from the following answers:  A) 10:5:1  B) 1:4:1  C) 8:4:1  D) 2:4:1  E) 4:3:2
By the assumptions as mentioned we have A=2B and B=5C. So A=2(5C) and we get A=10C. We have, therefore, A:B:C = 10C:5C:C. By cancelling the ratio with C we have 10:5:1. The answer is, therefore, 10:5:1.
