Dudee Uncle,
I have an answer but it is rather language based...I think if we replace each number in the magic square by the number of letters in each word..when these numbers are written in english then we will again have a magic square...I have already checked it for this problem and it works...and the magic constant for this new magic square is 21.
eg replace five with 4 twenty-two with 9 twenty five with 10 we again have a magic square..
6 11 4
5 7 9
10 3 8
but sahi uttar to sirf aapko hee pata hai...
Regards,
