Find the numbers which are in the ratio 3:2:4 such that the sum of the first and the second added to the difference of the third and the second is 28?
Select:	A) 4,3,22	B) 4,4,22	C) 12,6,16	D) 9,6,12	E) 9,2,23
Let the numbers be a, b and c.   a:b:c = 3:2:4   Given, (a + b) + (c - b) = 21   =&gt; a + c = 28   =&gt; 3x + 4x = 28 =&gt; x = 4   a, b, c are 3x, 2x, 4x   a, b, c are 12, 8, 16.   Answer:12,6,16
