A

Answer: A

Let C be x years old.
Then B is 2x years old.
And A is (2x)+2 years old.
So the equation is: x+(2x)+((2x)+2)=27
This simplifies to: 5x+2=27
Subtracting 2 from both sides gives: 5x=25
Dividing both sides by 5 gives: x=5
So C is 5 years old.
B is 25=10 years old.
A is (25)+2=12 years old.
Therefore, B is 10 years old.
