a : b = 3 : 4 and b : c = 2 : 1
Multiplying the second ratio by 2, we have
a : b = 3 : 4
b : c = 4 : 2
Therefore, a : b : c = 3 : 4 : 2.
=>a = 3k, b = 4k, c = 2k.
Since a, b and c are positive integers, their sum should be 9k, a positive integer.
From the options, only choice (3), which is 207, is a multiple of 9.
