When I read that averages are going to be distinct but the sum will be same, I used the magic square formula. I drew a sample square on the side. It helped me decipher that if a box has an average of 9, the average of other 2 boxes in that row/column can only be either 1 and 5 or 2 and 4. It helped me narrow down the pairs. That helped me solve the numbers much faster. Although, that didn't occur to me in the actual CAT exam, only ocurred to me now when I actually read the question, rather than just breezing through it. A very good question.
Valid argument. But as per the question the total score on day 5=18, which atleast requires each score to be 6. And if that's the case than C's unique maximum score can't be 6 it has to be more than that

How can score be 9 if it is mentioned that balls are between 1 and 9?
Sir why each box sum has to be multiple of 3?
There are nine boxes in two tables that means 9 +9 = 18 boxes why dont you see like that?
18:05 score should be 2,3,4,5,6,7,8. 1 and 9 are not inclusive. Then how chaturs max score is 9 ?
