Question

There is a question of class 11 in miscellaneous chapter 1, ques. 2 part 5  that , if x belongs to A  and  A is not subset of B , then x do not belongs to B.

I am satisfied by the answer, which is false.

For eg. If A= {1, 2,4 } and x =4  then x belongs to A .

Now B ={4,5,6} then A is not subset of B then also x belongs to B .

It should be true.

Give me an accurate and expanded ans.
