# Q.6 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}

Compare the elements of A,B,C,D,E,F,G,H.

$\in$ A but $8\notin B,8\in C,8\notin D,8\notin E,8\notin F,8\notin G,8\notin H$

Now, 2$\in$ A  but 2$\notin$C.

Hence, A$\neq$B,A$\neq$C,A$\neq$D,A$\neq$E,A$\neq$F,A$\neq$G,A$\neq$H.

$\in$ B,3$\in$D but 3$\notin$C,3$\notin$ E,3$\notin$F,3$\notin$G,3$\notin$H.

Hence,B$\neq$C,B$\neq$E,B$\neq$F,B$\neq$G,B$\neq$H.

Similarly,comparing other elements of all sets , we conclude that elements of B and elements of D are equal  also elements of E and G are equal.

Hencw, B=D  and E = G.
