From the sets given below, select equal sets

Monday, 7 April 2014

From the sets given below, select equal sets:

A = {2, 4, 8, 12}, B = {1, 2, 3, 4}, C = {4, 8, 12, 14}, 
D = {3, 1, 4, 2} E = {-1, 1}, F = {0, a}, G = {1, -1}, H = {0, 1}
Answer
The order in which the elements of a set are listed is not significant.
Set B and D both have elements 1 ,2, 3 and 4.
Hence B and D are equal set
Set E and set G both have element -1 and 1.
Hence, among the given sets, B = D and E = G.
