Let S = {1,2,10,20} and T = {a,b,c,d}. Then show that S ~ T but S ≠ T.

 Let S = {1,2,10,20} and T = {a,b,c,d}.      Then show that S ~ T but S ≠ T.

Solution:

    S = {1,2,10,20} and T = {a,b,c,d}

The number of element in the set S and T are same therefore set S and T are equivalent  S ~ T but S ≠ T
