Question

Consider the set A={1,2,3,4} . Find a proper subset B of A then find proper subset C of B. then find a proper subset D of C​

Answer 1

Step-by-step explanation:

Well there are many possible solutions . Here I give you idea how to do it .

By a proper subset we mean that subset set is not as same as original set or null set . So since given set A has 4 elements so It's subset should have 3 or 2 or 1 element . But since we need 2 more proper subsets . so B will have 3 elements , following C , 2 elements and D - 1 element .

Now choose elements as you wish

B - { 1 , 2 , 3 }

C - { 1 , 2 }

D - { 1 }

Answer 2

Answer:

$\large \dag$ Question :-

Consider,

• The set A={1,2,3,4}.Find a proper subset Bof A then find the proper subset C to B ,then find a proper subset D to C.

$\large \dag$ Some ideas :-

Here,

• I will share some of the ideas then you will get perfect answer to your question.. That is ,

Proper set :-

• It is nothing but A proper subset of a set A is not equal to A .In other words we can say that B is a proper set of A .Then all the elements of B is in A but A contains at least one element that is not in B.

Therefore,

We can tell according to the given question that is ,

• B element has B={1,2,3}
• C element has C={1,2 }
• D element has D={1}

I hope you got it .

$\large \dag$ Thank you .
