What is the logic ?

Answer 3

consider
a=1,
b=2,
c=3,
.
.
z=26.
here
(m+f+k) - (e+j+i) = (13+6+11) - (5+10+9) = 6.
(d+p+g) - (e+j+i) = (4+16+7) - (5+10+9) = 3.
(n+r+g) - (m+f+k)=(14+18+7) - (13+6+11)=9.
finally the "?" is exactly what you have guessed.
(n+r+g) - (d+p+g) = (14+18+7) - (4+16+7) =12.
so 12 is the answer.

Answer 4
