• 120 students attended the interview of company A or company B or company C. The number of students who attended the interview of company A is greater than that of company B,  which in turn is greater than that of company C. Also, the number of students who attended the interview of exactly one company is more than the number of students who attended the interview of exactly two companies, which in turn is greater than the number of students who attended the interview of exactly 3 companies. It is known that there is atleast one person who attended the interview of all three companies.

a. Find max. number of students who attended the interview of exactly 3 companies.
b. Find min. possible number of students who attended the interview of company A.
c. Find max. possible number of participants who attended the interview of company C.
d. What is the min. possible number of students who attended the interview of only company A?

• @laavanya-ramaul

120 = I + II + III (Where I - number of students who attended exactly one interview, II - exactly two interviews and III - exactly three interviews)
I > II > III
III is at-least 1

a) maximum number of students who attended exactly 3 companies.
We have to minimize I and II.
Let say x people attended all three. and let x + 1 attended exactly two companies and x + 2 attended exactly one company.
So 3x + 3 = 120
x = 39
