RodolfoValentino Posted May 13, 2014 Share Posted May 13, 2014 Ok lets start with an easy one :-) If one brick has the weight of 1kg plus half a brick, what is the weight (kg) of the brick itself? Try to explain you answer and do not cheat with google! :-) Link to comment Share on other sites More sharing options...
Rubberduck Posted May 13, 2014 Share Posted May 13, 2014 Well my time in school is far away and without cheating with google i only can hope that my answer is right. I take your informations into a simple math formula: 1kg + 1/2 brick = 1 brick |- 1/2 brick1 kg = 1/2 brick | *22 kg = 1 brick It seems like the brick has a weight of 2 kg.

RodolfoValentino Posted May 13, 2014 Author Share Posted May 13, 2014 Yeah that's right! Even if i dont understand the first step xDLets explain it this way for the next generation lol Brick = x 1x = 1kg + 1/2x1/2x + 1/2x = 1kg + 1/2x So for semplification:1/2x = 1kgthen1x = 2kg The daily champion of the quiz is Rubberduck, congrats mate! :-)stay tuned for the next one!

RodolfoValentino Posted May 14, 2014 Author Share Posted May 14, 2014 Ok here is the daily quiz :-) You are a farmer and you have to cross the river in front of you bringing your cabbage, your goat and your wolf to the opposite riverbank. The only way to do that is using your little boat that can transport you and only one of your 3 friend at time. You can't even leave alone the wolf with the goat or the cabbage with the goat either.. So what are you going to do? :-) Link to comment Share on other sites More sharing options...

RodolfoValentino Posted May 14, 2014 Author Share Posted May 14, 2014 Wooohooo the champion of the day is Erdrick! Congrats! A kind of spoiler tags for solutions here would be useful for other players joining the quiz :-)however this is gone, stay tuned for the next one! Planning some prizes :-) Link to comment Share on other sites More sharing options...
Erdrick Posted May 14, 2014 Share Posted May 14, 2014 I have a quick one: A princess is as old as the prince will be, when the princess is twice as old as the prince was, when the princess's age was half the sum of their present age. What then would be a possible age of the prince and princess? (dont cheat, use your noggin!) Erdrick 1 Link to comment Share on other sites More sharing options...
Freya Posted May 14, 2014 Share Posted May 14, 2014 P = princep = princess If I understood it correctly (which is unlikely): p = 2P AND p = (P+p)/2 Therefore: p = (P + 2P)/2 p = 3P/2 Thus a possible age for both would be: P = 20p = 30 Link to comment Share on other sites More sharing options...
Camden Posted May 14, 2014 Share Posted May 14, 2014 Ok here is the daily quiz :-) You are a farmer and you have to cross the river in front of you bringing your cabbage, your goat and your wolf to the opposite riverbank. The only way to do that is using your little boat that can transport you and only one of your 3 friend at time. You can't even leave alone the wolf with the goat or the cabbage with the goat either.. So what are you going to do? :-) 1. Take the goat over.2. Come back.3. Take the wolf over.4. Come back.5. Take the cabbage.6. Come back.7. Take the goat. There is this one with a family and a robber.

Camden Posted May 14, 2014 Share Posted May 14, 2014 Here is the link to the game, Japenese IQ Test: http://www.ranaldofamily.com/SWF/riverIQGame.swf Here are the rules. You can also write your answer in post. The goal is to get everyone across the river. Only 2 persons on the raft at a time. The father can not stay with any of the daughters, without their mother's presence. The mother can not stay with any of the sons, without their father's presence. The thief (striped shirt) can not stay with any family member, if the Policeman is not there. Only the Father, the Mother and the Policeman know how to operate the raft.

Erdrick Posted May 14, 2014 Share Posted May 14, 2014 P = princep = princess If I understood it correctly (which is unlikely): p = 2P AND p = (P+p)/2 Therefore: p = (P + 2P)/2 p = 3P/2 Thus a possible age for both would be: P = 20p = 30 You're on the right track, but I believe you are incorrect.

I am updating this as I do the puzzle. I may make more steps than necessary. I got stuck the first time and had to redo it! 1: cop and robber2: cop3: cop and boy4: cop and robber5: man and boy6: man7: man and woman8: woman9: cop and robber10: man11: man and woman12: woman13: woman and girl14: cop and robber15: cop and girl16: cop17: cop and robber Erdrick and Camden 2 Link to comment Share on other sites More sharing options...

Erdrick Posted May 14, 2014 Share Posted May 14, 2014 x=princessy=prince x=y+2y-[(x+y)/2]2x=y+2y-x+y3x=4yx=4/3y So for example princess 16yo and prince 12yo Is that right? Yes! Basically, as long as the prince is 3/4 the age of the Princess, it should work. so- (Princess/Prince) - 4/3, 8/6, 12/9, 16/12, 20/15, etc Erdrick 1 Link to comment Share on other sites More sharing options...

Would you mind PM ing me explaining how you constructed the logic, if you have spare time? Thank you Link to comment Share on other sites More sharing options...
