Two-only 12 + 9 + 7 = 28, plus all three 4 → 32.

180 − 2 × 60 + 3 × 10 = 90 (only A 40, only B 25, only C 25).
5.
Assertion–ReasonAssertion (A): If 40 of 60 students like X and 35 like Y, at least 15 students like both.
Reason (R): n(A ∩ B) is never less than n(A) + n(B) − Total.
Reason (R): n(A ∩ B) is never less than n(A) + n(B) − Total.
Correct Answer: A [Both A and R are true and R explains A]
Explanation:
R is the squeeze rule: the overlap is at least A + B − Total, because the union A + B − overlap cannot exceed the total; 40 + 35 − 60 = 15 gives A.
6.
