Answer 2

1) that's not correct
2) this doesn't have an "LGBARIDDLE" heading so im asking for solution

Answer 3

Answer 4

i think that's right, but let me double check

Answer 5

18 DAYS

Answer 6

yep, 13C2

Answer 7

all possible ways to choose 2 team out of 13

Answer 8

how are you all getting those?

Answer 9

and i've tried 13C2 @pizzapi it's not that

Answer 10

12 days. <-'
I guess

Answer 11

no. it's supposed to be 13 gamedays with 6 games each. but i don't know how

Answer 12

13C1?

Answer 13

wait, so all the teams play 6 games each?

Answer 14

i have no idea. i suppose it means each day has 6 games

Answer 15

13C2 divided by 6

Answer 16

since 6 games per day

Answer 17

but how do you know 6 games per day?

Answer 18

it wasn't given

Answer 19

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

Answer 20

6 teams can play 1 game everyday

Answer 21

that's the maximum possible games

Answer 22

per day

Answer 23

it's looking for minimum though

Answer 24

no, its 13 days, with 6 games per day

Answer 25

because a maximum of 6 games can be played per day

Answer 26

12 teams can play 6 games on day 1
repeat for day 2
etc.

Answer 27

i still don't get the logic why that's the solution

Answer 28

total games=13C2

Answer 29

maximum games per day=6

Answer 30

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

Answer 31

minimum days=total games/max games per day

Answer 32

@ganeshie8 each team can only play 1 game for day

Answer 33

*per

Answer 34

if you divide total by max..won't that make the final answer max?

Answer 35

oops ! bad logic disregard that
