Question

- 3 - 3x < 3 if x belongs to [- 5 - 4 - 3 - 2 - 1 0 1 2 3 4 5]
​

Answer 1

Answer:

Given, X={1,2,3,....,10}

and A={1,2,3,4,5}

Now, A−B={4}

⇒B=A−{4}={1,2,3,4,5}−{4}

={1,2,3,5}

∴X−{4}−B

={1,2,3,...,10}−{4}−{1,2,3,5}

={6,7,8,9,10}

Therefore,number of subsets B of X i.e., {6,7,8,9,10} =2

5
