In a class, the set of students playing cricket is \(C=\{Amit,Ravi,Sita\}\) and the set playing football is \(F=\{Ravi,Neha\}\). Which student(s) play both games?
Answer and explanation
Correct answer: \(\{Ravi\}\)
Students who play both games must belong to both sets, so we find the intersection \(C\cap F\). Comparing the two sets, Ravi is the only name appearing in both; Amit and Sita appear only in C, while Neha appears only in F. Therefore \(C\cap F=\{Ravi\}\), making option A correct. Option D is the union, which lists students playing at least one game rather than both.
