No idea is this hard or easy but believe or not, I invented this version and I say it is solvable, give a shot!
WARNING! THIS HAS NOTHING RELATED TO COMMON SENSE THOUGH
Three guys, Scawen, Victor and Eric went to brick shop and now they have exact amount of differently coloured bricks:
Scawen has 77½ Red Bricks|23 Blue Bricks|19 Yellow Bricks.
Eric has 30 Red Bricks|30 Blue Bricks|30 Yellow Bricks.
Victor has 0 Red Bricks|26½ Blue Bricks|24 Yellow Bricks.
Scawen gives now to Eric 4½ Bricks of each color. Eric gives to Victor 2 Red Bricks and 3 Blue Bricks. No one shares to anyone bricks anymore.
Random thief comes and steals 4 Full Bricks coloured Red/Blue From Scawen and Eric, ½ Blue Brick from Victor and ½ Blue Brick by randomly from those three guys.
All three Wants more Bricks:
Scawen wants three times more Red Bricks than Victor has total amount of Bricks at the end.
Eric wants twice more Blue Bricks than Victor has total amount of Bricks at the end.
Victor wants exactly total amount of 56 Bricks at the end.
Now You decide to buy 100 Yellow Bricks from the shop. Now you have also Bricks. You won't share any of your bricks to anyone or vice versa.
No one has more money, but Red/Blue Bricks are now FREE at local shop. You decide to help guys by carrying bricks to the them. You can carry up to 6 Full and only Full bricks per round, but not less than 1 Full Brick per round. 1 Round is counted when you go to carry the bricks from shop to guys and you.
Two thieves. Yann and Richard are interested about to steal Yellow Bricks.
Yann steals 1 Full Yellow Brick every 4th round from everyone you go to shop.
Richard steals ½ Yellow Brick every 9th round from everyone you go to shop.
Richard is the only one who can Split Bricks now.
Yann ONLY steals FULL BRICKS. ( No ½ ones at all! )
You decide to want to keep exact total of 100 Bricks at the end for you with no matter what colour they are now.
Now question is: How many bricks you bring up from the shop as total if subtracting the amount of stolen bricks from that amount?
EDIT: Sorry for stupid typos :P But now it is good to read, re-read again pl0x incase if, well yeah
EDIT: Only the "final result" matters!
