pay attention: What is the minimum number of days can they all play without any team playing more than one game a day?
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
6 teams can play 1 game everyday
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
that's the maximum possible games
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
it's looking for minimum though
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
no, its 13 days, with 6 games per day
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
because a maximum of 6 games can be played per day
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
12 teams can play 6 games on day 1 repeat for day 2 etc.
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
i still don't get the logic why that's the solution

im getting 12 days : first team finishes all its games(12) first day, second team finishes all its remaining games(11) second day, ... 12+11+10+9+8+7+6+5+4+3+2+1

minimum days=total games/max games per day

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
@ganeshie8 each team can only play 1 game for day
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
if you divide total by max..won't that make the final answer max?
 2 years ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.0
oops ! bad logic disregard that
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
no cuz the minimum would be 1 game per day
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
you are trying to minmize the number of days, by fitting the most games in one day

I don't think you're reading the whole question and given correctly.

what dp you mean @panlac01 ?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
is there a different solution?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
13C1 gives the same result though...
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
13 teams..one game per day...so 13C1 would make sense right?
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
no, there must be a total of 78 games
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
13 teams must play all the other teams
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
isn't that what 13C1 means?
 2 years ago

panlac01 Group TitleBest ResponseYou've already chosen the best response.0
with 13 teams, only 12 teams can play in one day
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
no 13 C 1 means the number of ways you can select 1 team from 13 teams
 2 years ago

panlac01 Group TitleBest ResponseYou've already chosen the best response.0
the question is, what is the minimum day that they can ALL play without any team playing more than 1 team a day
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
so what are you implying?
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
12 team playing on 1 day=6 games in total for the day
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
this was a question in a board exam back in '94 so it's meant to be tricky
 2 years ago

panlac01 Group TitleBest ResponseYou've already chosen the best response.0
in the first day, you are left with one team unable to play
 2 years ago

panlac01 Group TitleBest ResponseYou've already chosen the best response.0
so you need to move on to the second day to give that specific team who didn't play to play.

i really think 13C1 makes sense
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
in the case of (13C2)/6...why divide by 6? of all the numbers?
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
6 is the number of games played in 1 day by 12 teams
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
but what about for the case of 13 teams?
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
only 12 teams can play per day because they have to be grouped in teams of 2
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
i don't think that means the other team should be disregarded
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
its a 1v1 match, 2 teams per game
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
okay, on the first day team 1 vs 2 3 vs 4 5 vs 6 7 vs 8 9 vs 10 11 vs 12 the 13th team can't play because all the other teams have already played a game
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
yes i get that. but im asking for the case of 13 teams. is that logic applicable in that case?
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
you used 13C2 and then divided by 6 (which is for 12 teams)
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
13C2 represents the total games because you are select teams of 2 out of 13 teams if you organize all the games, 6 games per day, it would take 13 days in total
 2 years ago

pizzapi Group TitleBest ResponseYou've already chosen the best response.1
*groups of two teams out of 13 teams

panlac01 Group TitleBest ResponseYou've already chosen the best response.0

(13C2)/6 I really need to work on explaining things, hopefully openstudy will help me with that
 2 years ago

panlac01 Group TitleBest ResponseYou've already chosen the best response.0
don't worry bro, you got it from the first time. Illustration makes a better explanation sometimes.
 2 years ago

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
so do you agree with pizzapi already @panlac01 ?
 2 years ago

PhoenixFire Group TitleBest ResponseYou've already chosen the best response.1
@pizzapi Is right. Because there has to be a total of 78 games played for each team to play each other team. It asks for the minimum number of days for these 78 games to be played in (at least that's the interpretation of the question). So to find that you divide 78 by the maximum number of games that can be played on a single day, which is 6. Therefore, 78/6=13. It takes 13 days for all teams to play each other.
