Razli is m years old. Stanely is twice as old as Razli. Theo is 3 years older than Stanely. How old was Theo 2 years ago?

R=m

S= m ^ 2 

T= S + 3

Theo was m ^ 2 + 1

There are infinite solutions to this...for instance :

Razli                 Stanley           Theo

6                        12                   15        →    and Theo was 13, two years ago

10                      20                   23        →    and Theo was 21, two years ago

etc.
