My question to you is: What is the exact age of the person in the red t-shirt?

Maybe I should pass on how I work out my age (mod 25)! Well I suppose that actually describes my mental age, but nevertheless it works. I'll add to this post later tonight with the answer, which I hope is correct, and how I obtained it.

(Without giving it away for those who would like to attempt it, is the answer a multiple of 3? Just so I know I did it right!)
