1.

D= {x:xis a factor of 21,x€N}

Answer» ONG>Answer:Here, `A = {1,2,3,4,5,6,7...}`

`B = {2,4,6,8,10...}`

`C={1,3,5,7,9...}`

`D={2,3,5,7,11...}`

Now, `AnnB={2,4,6,8,10,...} = B`

`ANNC = {1,3,5,7,9...} = C`

`BNNC = {}->` As there is no common ELEMENTS.

`AnnD = {2,3,5,7,11...} = D`

`BnnD = {2}`

`CnnD = {3,5,7,11...} = D-{2}`
