The sum of the present ages of A, B, C is 27 years. Three years ago their ages were in the ratio 1:2:3. What is the present age of A?	Pick
A) 10 B) 6 C) 8 D) 9 E) 7
Three years ago:   a:b:c = 1:2:3   Let a = 1x, b = 2x, and c = 3x.   Today:   (x+3) + (2x+3) + (3x+3) = 27   x = 3   So the present age of A is x+3 = 6   The answer is 6.
