hiiiii how to practice this expls…..which is the good book or website plz tell

2. PATOORI POOJITHA REDDY

first you have to divide given problem into three parts –

(1)E J M (2) E J M (3) E J M
N I D
—————- ——————- ——————

M J A N S I A S I S S A
—————- —————— ——————–

Now, in (1)
we have M*N=N It is possible either M=6(N=2 or 4 or 8) or N=5(M=3 or 7 or 9)
first take N=5 and M=3
E J 3
5
————–
3 J A 5
————–
here possible of J are {0,1,2,4,6,7,8,9}
try with J=0
E 0 3
5
————–
3 0 1 5
————-
Therefore E=6;

6 0 3
5
————-
3 0 1 5
————–
next in (3)

D*M=A here A=1.It is possible 7*3=21 or 3*7=21
therefore D=7

6 0 3
7
————-
4 2 2 1
—————

here we get I=4

therefore 6 0 3
4
——————
2 4 1 2
—————–

therefore E=6,J=0,M=3,D=7,I=4,N=5,K=9,A=1,S=2.

Thier is no specific book for Crypto arithmetic problem, You just need to practice more examples.😃
