A=5 OR 6 SINCE H*A=A SO A=5
A*D=R SO D WILL BE EVEN NO D=2,4,6,8 SO R=0 AS 5*EVEN NO WILL GIVE UNIT DIGIT 0
D+S+A=S SO D+A HAS TO GIVE 10 BT SINCE D IS EVEN AND A IS ODD SO THERE WILL BE A CARRY FOR IT TO BE 10 D+A+1=10 AS A=5 SO D WILL BE 4
TEA*A=HRSA IF E IS EVEN S WILL BE 2 AS THERE IS A CARRY OF 2(5*5=25) AND IF E IS ODD S WILL BE 7

NOW TAKE S=7 L+R+D=S L=2 YOU CAN TAKE S=2 AND CHECK BT IT WILL NOT SATISFY

E+1=L SO E=2

TEA*D=LDTR T15*4=24T0 USE THIS AND YOU WILL GET T=6

TEA*H=EWDA 615*H=1W45 H HAS TO BE ODD

H+W SHOULD BE 11 SO H WILL BE 3 AND W=8

@ arvind
As u can see A=5, A*D will always have 5 or 0 in units place,
So R can only be 5 or 0 (bt A=5)
Therefore R=0...

@alok kumar
from ur explanation, read the second line
"A*D=R SO D WILL BE EVEN NO"
A is odd, which is fine, but for D to be even R has to be even.
what is the logic behind assuming R to be even??
if any1 undrstood please do explain
