Question : 12
Total: 73
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}
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}
Solution:
From the given sets, we see that sets B and D have same elements and also sets E and G have same elements.
∴ B = D = {1, 2, 3, 4} and E = G = {–1, 1}.
∴ B = D = {1, 2, 3, 4} and E = G = {–1, 1}.
