- 1) c*e=c it means 6*2=12,6*4=24, 6*8=48
2) h+h is not give carry it means h =1,2,3,4 not more than 4 bz 5+5=10 its generate carry
3) e+j+j=e in this case may be j=0

- 1) h+h=b,so h=1,2,3,4.....h have no carry
2)E*c=c....so put there 6*2 or6*4 or 6*8
now ,we put 6*2 ,thn it fail
again we put 6*4 and H=1 and H+H+c1=B.so B=3..
thn we get solution...

- As C*E=C . So,for this equation 2*6=12; 4*6=12; 8*48 will be applicable.E will be 6 for sure.
Now if we select 2*6=12. We will stuck in doing the multiplications with E.
So we will select 4*6=24.
Now, As E+J+J=E ,So E will definitely 0 or 5.
As 4 & 6 are already booked and 1 can't be B . So, we start with 2 . As it will not fit in our criteria As J should come 0 or 5. So, B will be 3, it fulfills our requirement .
Since H+H+carry=B. Hence H==1.
as we know the value of E & C and we know the carry for that equation will be 2 , So solve the equation A*6+2=14.From this A will come 2.
On the solution we can see the equation H+C+D=A . We can put all the values then D will come 7.
Now, Only 0,5&9 digits are left over there.
F can't be 0.
So,start with 5 and it will fulfill our all solution.

take J=0 and E=6
bcz J+J+E+[C]=E so J+J+[c]=10 so j wil be 0 or 5 but 5 is not possible here bcz E*C=C - 9 years agoHelpfull: Yes(0) No(0)
