As we learnt 

 

EQUAL SETS -

 

Two sets A and B are said to be equal iff they have exactly the same elements and we write A = B. Otherwise, the sets are said to be unequal and we write A B.

- wherein

eg. A= {3,2,1,4} and B= {2,3,4,1}

 

 Clearly A_1 and B_1 are equal sets since they have exact same elements.

 


Option 1)

A_{1} is a set of letters of ALLOY and B_{1} is a set of letters of LOYAL.

Option 2)

A_{2}={n:n\epsilon Z\: \: and \: \: n^{2}\leq 4}  andB_2={{n:n^{2}-3n+2}=0}

Option 3)

A_3={x:x^{2}= 9}  and B_3={3}

Option 4)

A_4={x:x is a vowel}  and B_4={a,e,i,u}
