A. (16)
Concept
At least one is (31+29-11=49), so neither is (65-49=16). In survey questions, finding the union first is useful.
Why this answer is correct
The correct answer is A. (16). At least one is (31+29-11=49), so neither is (65-49=16). In survey questions, finding the union first is useful.
Exam Tip
कम से कम एक (31+29-11=49) है, इसलिए कोई नहीं (65-49=16)। सर्वे प्रश्नों में पहले संघ निकालना उपयोगी है।
