This is a old one.

 

In the following addition sum, ten letters have been used consistently to replace the ten digits 0-9.
The sum will total correctly when each letter is replaced by the appropriate digit.

ELEVEN
THREE
THREE
  ONE
  ONE

TWENTY

What is the 6-figure total represented by TWENTY?

I am throwing it again here.

I think there might be more than one answers as L,V,H and R are independant of TWENTY, I found one of them is

332232

My result based on following values

N	2
E	2
O	2
T	3
H	4
L	6
V	3
Y	2
R	6
W	3

Correct me If I am wrong.

In my question, each letter represent different unique digit. I am afraid you are wrong this time.

TWENTY is 645368. Now guess what is others? anyone

L=0,V=1,O=2,N=3,W=4,E=5,T=6,R=7,Y=8,H=9.

ELEVEN=505153

THREE=69755

ONE=235

TWENTY=645368
