Six countries in a certain region sent a total of 75 representatives to an international congress, and no two countries sent the same number of representatives. Of the six countries, if Country A sent the second greatest number of representatives, did Country A send at least 10 representatives?
(1) One of the six countries sent 41 representatives to the Congress.
(2) Country A sent fewer than 12 representatives to the Congress.
The question stem asks whether A≥10.
Plug in A=10 (which satisfies statement 2 and is at least 10) and A=9 (which also satisfies statement 2 but is NOT at least 10).
To save time, let F=41, which satisfies statement 1.
Case 1: Total = 75, F=41, A=10.
Remaining representatives for B, C, D and E = 75-41-10 = 24.
The following combination works for B, C, D and E:
B=9
C=8
D=6
E=1.
Thus, it's possible that A=10.
Case 2: Total = 75, F=41, A=9.
Remaining representatives for B, C, D and E = 75-41-9 = 25.
The following combination works for B, C, D and E:
B=8
C=7
D=6
E=4.
Thus, it's possible that A<10.
Since it's possible that A=10 or that A<10, the two statements combined are INSUFFICIENT.
The correct answer is E.

(1) One of the six countries sent 41 representatives to the Congress.
(2) Country A sent fewer than 12 representatives to the Congress.

> Total number of reps from 6 countries = 75;
> Country A sent the second greatest number of reps
Question: Did Country A send at least 10 reps?
Let's take each statement one by one.
(1) One of the six countries sent 41 representatives to the Congress.
Since 41 > 75/2, the country, which sent 41 reps, must be the country that sent the greatest number of reps.
Case 1: Say Country A sent 10 reps, thus, the remaining 4 countries, together would have sent 75 - 41 - 10 = 24 reps. This is possible, for example, the four countries sent 9, 8, 6 and 1 reps, respectively. The answer is Yes.
Case 2: Say Country A sent 9 reps, thus, the remaining 4 countries, together would have sent 75 - 41 - 9 = 25 reps. This is possible, for example, the four countries sent 8, 7, 6 and 4 reps, respectively. The answer is No.
No unique answer. Insufficient.
(2) Country A sent fewer than 12 representatives to the Congress.
Both the cases discussed above are applicable here too. So, even combining the two statements will not suffice. Insufficient.
The correct answer: E
Hope this helps!
