Hi,

this was my approach:
because VESLO is also 5 digits long, K must be less then 1/6 of 10 which means it´s 1.
That make O=6.
"V" must be greater or equal 6 and not equal "O". So it is greater equal 7.
"A" must be less then 6 in order to keep the sum 5 digits long.

The rest was more or less brute force.
I saw that A=3 and A=4 did not work well because of repeating digits on the VESLO side.

What I would like to know:
Is there a more elegant approach to the solution of this riddle ?

Regards
Shryke

Found the answer mostly thru trial and error.
Like Shryke, I knew K=1 and therefor O=6, because VESLO was only 5 digits long like KAJAK.
"V" then had to be >6. Substituting numbers>1 I soon found that "A" was not 2,3, or 4.
Everything soon fell into place and I had the answer.
