1.	If A-B=B-A then A and B are ____________(a) equivalent sets(b) equal sets(c) disjoint sets(d) empty setsThe question was posed to me during an online exam.Enquiry is from Operation on Sets-2 in section Sets of Mathematics – Class 11
Answer» Right CHOICE is (B) equal sets Easiest explanation: A-B is the SET of elements that belongs to A but not to B and B-A is the set of elements that belongs to B but not to A. A-B=B-A is POSSIBLE only when A and B are equal sets.
