Question

Identify the type of set $A^{\prime }=\{1,2,6,7\}$ and $B=\{6,1,2,7,7\}$

• A. Overlapping Sets
• B. Unequal Sets
• C. Equal Sets
• D. None of these

Answer 1

Answer: (C)

Equal Sets

The two sets $A$ and $B$ are called equal sets if all the elements of $A$ are present in $B$ and all the elements of $B$ are present in $A$.

Here all the elements of $A^{\prime }$ are present in $B$ and all the elements of $B$ are present in $A^{\prime }$. Hence they are equal sets.
