In order to play a certain game, 24 players must be split into n teams, with each team having an equal number of players. If there are more than two teams, and if each team has more than two players, how many teams are there?

(1) If thirteen new players join the game, one must sit out so that the rest can be split up evenly among the teams. (2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams.

As the OA is not provided, I would like to double check my solution for this problem. This is how I solved it.

Considering the Question Stem

Total players = 24 Number of Teams > 2 Players in each Team > 2 Number of Teams ---> We have to find.

Considering Statement 1

13 players join. So total players = 24+13 = 37. 1 sit out, so total players 36. So now the number of teams can be 18, 12, 9. Therefore insufficient

Considering Statement 2

7 new players join. So total players = 24 + 7 = 29. 1 sit out, so total players 28. Again, the number of teams can be 14, 7, 4. Therefore insufficient.

Combining the two statements - > We can't calculate the exact number of teams and therefore my answer is E. Can you please check and let me know your thoughts guys?

In order to play a certain game, 24 players must be split into n teams, with each team having an equal number of players. If there are more than two teams, and if each team has more than two players, how many teams are there?

Given: n>2 and 24/n>2, so basically n is a factor of 24 satisfying both requirements (2<n<12). n can take the following values: 3, 4, 6, and 8. Question: n=?

(1) If thirteen new players join the game, one must sit out so that the rest can be split up evenly among the teams --> (24+13)-1=36 is also multiple of n --> n can be: 3, 4, or 6. Not sufficient.

(2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams --> (24+7)-1=30 is also a multiple of n --> n can be: 3, or 6. Not sufficient.

when looking at each statement they give new scenarios but the we can only look at number of teams that match the original number of teams example in stmt 2 there's 30 ppl to make teams and factors are 3,5,6 but 5 is not a factor of 24

Grouping theory of divisibility helps you solve many questions very quickly, very easily and by just using a little bit of imagination. I would strongly advise you to check it out: http://www.veritasprep.com/blog/2011/04 ... unraveled/

I will show you how it is applicable in this question:

"In order to play a certain game, 24 players must be split into n teams, with each team having an equal number of players." There are 24 people. They are divided into groups with equal no. of people. They could be divided into 3 groups (8 people each) or 4 groups (6 people each) or 6 groups (4 people each) or 8 groups (3 people each). Once we know how many people were there in each group, we can find out the number of groups.

(1) If thirteen new players join the game, one must sit out so that the rest can be split up evenly among the teams. 1 player sits out so the rest of the 12 people can also be divided into groups of 6 people each or 4 people each or 3 people each. It is not sufficient to know how many people were there in each group.

(2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams. 6 people can also be made to form a group of 6 people or two groups of 3 people each.

Using both statements, we see that the groups could consist of 6 people each or 3 people each. So together they are not sufficient.

Thank you for the descriptions. I did not think of the factor approach. It makes sense to think of this problem as they are asking for N which is 2 < N < 24, and N are the factors of 24, which are 3, 4, 6, 8. Now statement 1 can have 12 divisible by 3, 4, 6 so not suff. and statement 2 has 6 divisible by 3, and 6 so not sufficient. Thank you.

(1)+(2) n can still be: 3 or 6. Not sufficient.

Answer: E.

Can You please explain me how (1)+(2) will appears? I mean what is the statement after combining (1)+(2)

From (1) we have that n could be: 3, 4, or 6. From (2) we have that n could be: 3, or 6.

So, when we combine we get that n could be 3 or 6.

; The question would had been solvable in case the statement were like ; 4 people joined and were accommodated or 4 people joined and 1 had to sit out for even distribution.

The question would had been solvable in case the statement were like ; 4 people joined and were accommodated or 4 people joined and 1 had to sit out for even distribution.

I think it's below 600 level question...Your thoughts please!

I will stick with 600-700

Some people could start off thinking it's a Permutation Combination problem. You cannot make an equation and solve it. You can imagine the scenario and see the answer quickly if you understand the concept of division - it may not be that clear otherwise.
_________________

You are using too many variables. Use only as many as you actually need.

Question says 24/n = an integer

Statement 1: 24+13 = 37 gives remainder 1. This means 36/n is an integer. Common factors of 24 and 36 are 3, 4, 6 which can equal n. Hence, not sufficient.

Statement 2: 24+7 = 31 gives remainder 1. This means 30/n is an integer. Common factors of 24 and 30 are 3, 6 which can equal n. Hence not sufficient.

Together, n can be 3 or 6. So answer (E)

(2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams.

hey.. 24 players to be split into n teams with m players each....

1) If thirteen new players join the game, one must sit out so that the rest can be split up evenly among the teams. Total no. of players now: 24+13= 37 One must sit out, hence no. of players: 36 With 36 players: n=6, m=6; n=3, m=12; n=12, n=3; i.e there are many ways for the team to be arranged.. Hence, INSUFFICIENT.

(2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams. Total no. of players now: 24+7= 31 One must sit out, hence no. of players: 30 There is more than one possibility for the team: n=5, m=6; n=6, m=5. Hence, INSUFFICIENT.

1 and 2 together: There are no common values.. Hence, INSUFFICIENT. ANS:E

conditions: 1).24 players. 2).each team having an equal number 3). more than two teams 4) each team has more than two players

(1) If thirteen new players join the game, one must sit out so that the rest can be split up evenly among the teams.

total players now = 24+13 =37 remove 1 = 36 this cab be divided in 9 x 4...and ...12 X 3 ....6x6....4x9....3x12....9x4.......(teams x player) NOT SUFFICIENT

(2) If seven new players join the game, one must sit out so that the rest can be split up evenly among the teams. Total players now = 24 + 7 =31 remove 1 = 30 options available = 3x10 5x6 6x5 10x3 (teams x player) more than options available not sufficient.

combining also we have 2 options. not sufficient

hence E
