Ok..
Pot at grounded point is zero...
Potential at A is clearly +12 ...(is it clear?)
pot at D is -6... (clear?)
so pot diff across resistances is 18..
so i=3
so potential diff accross 1 ohm is 3 (3*1) (.....I*R) so pot of B=12-3=9
pot diff across 2 ohm is (3*2) so pot at C=9-6=3
pot diff across 3 ohm is (3*3) so pot at D =3-9 = -6 (which was clear above and is proof that there is no calaculation mistake above

see the point earthed has 0 potential,so lower terminal of upper battery has 0 potential
Now upper terminal of lower battery will be at 0 potential
and the upper terminal of upper battery at 12V,and lower terminal of lower battery at -6 V
also equivalent of batteries=18V
18=6I
I=3A
Remaining can be easily done
plz denote clearly d positive n negative potential of d battery.
it looks lik a capacitor.
assuming both upper plates of battery are +ve...
pot at A=+12
B=+9
C=+3
D=-6
