Question

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

Only in pair of sets B and D where (N.C.E.R.T.)

B = {1, 2, 3, 4} and D = {3, 1, 4, 2} and in pair of sets E and G where

E = {-1,1} and G = {1, -1}, the elements are exactly same.

Hence, B = D and E = G.

In all other cases, either the number of elements or the elements or both are not the same.

Hence, the other pairs are not equal.
