Correct Answer

A. \((W'={\)सोमवार,मंगलवार,बुधवार,गुरुवार,शुक्रवार})\((W'={\)Monday,Tuesday,Wednesday,Thursday,Friday})

Step 1

Concept

(W) is the set of weekend days, so (W') contains the other five days. Always find complement with respect to (U).

Step 2

Why this answer is correct

\(The correct answer is A. (W'={\)सोमवार,मंगलवार,बुधवार,गुरुवार,शुक्रवार\(}) / (W'={\)Monday,Tuesday,Wednesday,Thursday,Friday}). (W) is the set of weekend days, so (W') contains the other five days. Always find complement with respect to (U).

Step 3

Exam Tip

(W) सप्ताहांत के दिनों का समुच्चय है, इसलिए (W') में बाकी पांच दिन आएंगे। पूरक हमेशा (U) के संदर्भ में निकालें।
