1) No number was chosen by more than 3 people.
2) More people chose the number 5 than the number 4. 1) No number was chosen by more than 3 people.there are 12 people and they have to choose any of the 5 numbers.. worst case  all 2, 3, 4 and 5 were choosen by 3 each.. so total = 4*3 =12.. hence no one chose 1.. NO In all other scenarios, some one chose 1..YES Insuff 2) More people chose the number 5 than the number 4Nothing much Insuff combined..it tells us that 4 was not choosen by 3 but less than 3.. so worst case 2, 3, and 5 were chosen by 3 each and 4 by2.. total 3*3+2 = 11.. so atleast ONE chose 1 Suff C

1) No number was chosen by more than 3 people.
2) More people chose the number 5 than the number 4. The language in (1) threw me off and I was not able to understand what was going on in the question. For someone who is also confused by it, all it says that "a number can not be selected more than 3 times".With that in mind, here is the solution: (1) The constraint is that no number can be selected more than 3 times. Case 1: Is it possible that 1 is not selected at all with this constraint? Yes, that is possible. 12 people can pick numbers { 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5 } and still meet the constraint in the condition. Case 2: Is it possible that 1 is selected at least once with this constraint? Yes, this is also possible. 12 people can pick numbers { 1, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5 } and still meet the constraint in the condition. Since both the cases are possible, this condition is INSUFFICIENT. (2) This condition only tells you that 5 is selected more times than 4Case 1: Is it possible that 1 is not selected at all with this constraint? Yes, that is possible. Consider 12 people picking numbers { 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 } and still meeting the constraint in this condition. Note that this is only 1 possible case out of many such cases in which 1 will not appear and we can have more 5s than 4s.Case 2: Is it possible that 1 is selected at least once with this constraint? Yes, this is also possible. 12 people can pick numbers { 1, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 } and still meet the constraint in the condition. Note that this is only 1 possible case out of many such cases in which 1 will appear and we can have more 5s than 4s.Since both the cases are possible, this condition is also INSUFFICIENT. (1) + (2): Since a number can only be selected at most 3 times and there are more 5s than 4s, consider this: If 1 is not selected, the only possible selection that satisfies condition (1) is { 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5 } BUT this selection does not satisfy (2) condition. With similar reasoning, you can see that if you try to satisfy (2) condition you will break (1) without having 1 selected by at least 1 person. Hence, for both the conditions to be true simultaneously, 1 should be selected by at least 1 person. SUFFICIENTAnswer: C

1) No number was chosen by more than 3 people.
2) More people chose the number 5 than the number 4. Statement 1. 3 people choose 2, 3 choose 3, 3 choose 4 and 3 choose 5. Hence the answer is No. Another scenario. 1 person choose 1, 2 people choose 2, 3 choose 3, 3 choose 4 and 3 choose 5. Then asnwer is Yes. Insufficient Statement 2. 11 people choose 5 and 1 person choose 4. Answer is NO. Or 10 people choose 5, 1 choose 4 and 1 choose 1. Answer is Yes. Insufficient. Both statements together. If number of people who choose 5 is more than number of people who choose 4 and maximum number of people to choose any number is 3 then 1 person is left out and can only choose 1. Sufficient
