Yes, that's true, sometimes we do have assumptions in such a scenario but for more clarity, the question should have mentioned that there should be atleast 1 delegate in each of the conference for each of the clgs.

Alright, Thank you sir.

Alright, Thank you sir.

Question's language In this line the question states that not more tha 5 delegates were sent from 1 B-school, and there is nowhere mentioned that every B-school has to compulsorily send atleast 1 delegate to any conference. So, from the above given language, we can conclude that the possible values of students in a conference from a single B-school can be 0,1,2,3,4,5. But the solution does not contain 0 as a possibility. Why is it so?5 B-School.png 891.14 KB
