Finally you will have HAHHH =12111, and 1+2+1+1+1=6 divisible by 3, it is B

1-2+1-1+1=0 divisible by 11 (12111=11*1101) it is C

Yes, I love you man! :lol: , it is C. "1-2+1-1+1=0" is a rule, may you generalize it?

Yup I got it !

I still am not sure about the approach, I tried with hit and trial and seeing the pattern went ahead with 1 in place of H, what is the general approach in such problems?
