Dolly is 9 years old and her aunt is 27 years old.

Let Dolly's current age be #x# years

We are told that when Dolly was born her aunt was 18.

Hence, the aunt was, and continues to be, 18 years older than Dolly.

So, the aunt's age now is: #x+18#

Then we are told that the aunt's current age is three times Dolly's age.

#:. x+18 = 3x#

#2x=18 -> x=9#

So, Dolly is 9 years old.

Therefore, the aunt must be: #3xx9 = 27# years old.
