ans 12
H,I,D are distinct prime nos, can be 2,3,5,7
HI,DI are prime, so options are 23,53,37 since I occurs in both and 3 occurs 2 times in nos I is 3
so HI/DI =23/53
N and G are not prime so options are 4,6,8,9 (1 is neither prime nor composite, neglected)
NG also prime, from options only 89 possible
N=8=2^I=2^3
take H=2 D=5 since both are added take as u like
therefore, 2+3+5+3 +8-9 = 12

i=3;h=2;d=5;then n=2^i=2^3=8
then g=7 (because ng is a prime number so, ng=87)
hence, H+I+D+N-G=2+3+5+8-7=11

Question is incomplete, One more condition was there HIH is divisible by (2D+1)
So,according to this I=3,H=5,D=1,N=8,G=7
H,I,D are prime numbers
HIH is divisible by (2D+1)
HI, DI, NG are two digit prime numbers

suryakant singh  (8 years ago)

H=7,I=3,D=5
HI=73 prime,DI=53,N=8,NG = 89
then HIDING is also prime, HIH = 737 is also divisible by 2D+1=11
so,7+3+5+8-9=14
answer is 14
