I am not explaining why A is wrong as you also eliminated it. Here is reason for why B is wrong.

6 countries total 75 representative. If B true then A sent less than 12 representative. A can send any representative from 1 to 11, then what proof is there it sent only 10 or 11 representative.

Even if we combine both equations 1 country sent 41 and other sent 71-45 = 26 countries. There be many possibilities in which country A's representation can be less than or equal to or more than 10. E.g. 10,1,2,4,9 or 9,1,2,4,10, or 11,1,2,4,8.

1) one of the country sends 41 reps.
Which means that 75-41=34 reps for the rest. Now, there is one more criteria, that A should send the second highest number of reps. we should take two cases to prove 1) is may or may not be true. Pick A=9 reps which leaves 25 reps for 4 countries and they can be easily spread with no overlaps(satisfying on other condition). Now, pick A=10 (as it is mentioned atleast)- when A=10, there are 24 reps left that can also be spread across the rest of the 4 countries. Hence, 1) does not answer the question definitively. Hence, choice A and D are ruled out.

2) Country A sends fewer than 12 which means upto 11 reps. Now again pick A=9 and since, A sends the second highest number of reps, one other country sends >9 say 10 reps which leaves, 56 reps to be spread among rest of the 4 countries. Now, pick A as 10 and another country that sends more than A as 11 which leaves, 54 reps to be spread among the 4 countries.
Since, A can send 10 or 9 reps and still satisfy the conditions, we cannot answer the question with statement 2.
Hence, choice B is ruled out.

Combining 1) and 2) gives- one of the country sends 41. Pick A=9 and A=10 and apply the same process as before which satisfies the conditions for both A=9 and A=10- does not give a definitive answer. Hence C is not sufficient.

So, the answer should be E. What is OA?

Really?What good is your clear E doing here. If it is that clear "share your" method. May be that will add some value to the post.

I post questions here to understand why my approach to a problem is incorrect and learn from my mistakes and not to quantify how clear the question is to you.

A+B+C+D+E+F = 75

First consider (1) & (2) together:
from (1) A+B+C+D+E = 75-41 = 34
One possible solution of A satisfying both (1)&(2) statement:
A+17+1+2+3 = 34
A = 11
Another possible solution of A satisfying both (1)&(2) statement:
A+24+1+2+3 = 34
A = 4
So, Not Suff

Ans is E
