Question

Given that A = {x : x is a even natural number less than or equal to 10} and B = {x : x is an odd

natural number less than or equal to 10}

Find:

(i)

A -B

(ii)

B -A

Answer 1

Answer:

firstly A = { 2, 4 , 6, 8 , 10}

& B = { 1, 3 , 5, 7, 9}

now

A-B (only A) = {2, 4, 6 , 8 , 10, }

therefore A-B= { x : x is a even natural number less than or equal to 10}

B-A (only B) = { 1, 3 , 5, 7, 9}

therefore B-A = {x : x is an odd

natural number less than or equal to 10}

Answer 2

Given ,

A={x:x is a even Natural number < or = 1 0 }=)A={2,4,6,8,10}

B={x:x is an odd Natural number < or = 10}

=)B={1,3,5,7,9}

1) A-B={2,4,6,8,10} - {1,3,5,7,9}

={2,4,6,8,10}

2)B-A={1,3,5,7,9} - {2,4,6,8,10}

={1,3,5,7,9}
