Time it was somebody got the answer (you guessed, right?).
Scoreboard:
Cirno - 8
Blue Phoenix - 6
Lauli - 5
NightElb - 2
RectumHoward - 1
Question 14 (5 points):
A number with 1000 digits (namely 200820082008...) needs some digits removed to get the cross sum 2008. How many digits can you MAXIMAL remove from that 1000-digited number to get the cross sum 2008?
(Fun fact: This was a question in the Känguru of Mathematics today. And I solved it in short time :P (I know I'm a show-off xD))
