The sum of the digits of N*k
(for k=any positive integer below 73)
is 36.
Find N.
Bonus: What is the significance of the number 36 in Judaism,
especially relating to forever?
(In reply to
re: The last one by Ady TZIDON)
I did a quick search fruitless. I'll do it mre extensive but not now.
As for the k value:
9*11=99
99*101=9999
999*1001=999999
9999*10001=99999999
If k<10001 k*9999 has 36 as sum of digits.
