- through last line we get C+1 = E
last to second line we can write C+1+G = C
let us assume that we get 2 as carry
then C+1+G+2 = C
G+3 = 10 ->G = 7
last to third line A+G+D = C(carry 2)
to get carry 2,A+D should be greater than 14(so A and D also should be big values)
we hv BCD * G(7) = AFBA, with this we come to know that A can hv max value 6 (because multiple of 7)
and by some multiplications we get D = 8
now we hv BCD and G so we can multiply BCD * G we get A,F values
and finally we can get all values - 10 years agoHelpfull: Yes(5) No(1)

- (D*F=C, D*E=F)
(2*4=8
2*7=14)
(2*8=16 ,2*4= 8).........ALL PAIRS ACC. TO d
...
....
.........
(8*2=16, 8*4=32), (8*4=32,8*3=24)
THIS PAIR= (8*4=32, 8*3=24 ) Satisfy the values of D,F,C,E
D=8 F=4 C=2 E=3
B28*E=CGDF
B28*3=2G84 USING HIT AND TRAILS FOR B... B=9.
928*3=2784
B=9,G=7
PUT ALL THIS VALUES AND FIND ANOTHER VALUES
