SETS

Which of the following collections are sets.

i) All good books in your library.

ii) All planets in the solar system.

iii) All beautiful flowers in your garden.

iv) Three good persons in India.

• (i) and (ii)

• (II) and (iii)

• (i) and (iii)

• None

If set A = {.....,-3,-2,-1,0,1,2,3,4,......} and set B = { -5,-2,1}, then find the statement which is not correct?

• B $\subset$ A

• B $\in$ A

• 6 $\in$ A

• None

If 6  $\notin$  B, then the possible equal set of B among the following is 

• {x/x is a multiple of 2}

• {x/x is a multiple of 3}

• {x/x is an even integer}

• {x/x is an odd integer}

If set A contains vowels in the word "ECONOMICS", then the set Q is

• {E,O,O,I}

• {E,O,I,S}

• {E,O,I}

• Both A & C

C = {f, l, o, w}

• {x : x is a letter of the word FLOW}

• {x : x is a letter of the word WOLF}

• {x : x is a letter of the word FOLLOW}

• All of the above

Choose the finite set

• The set contain the points in a Line.

• The set contain the vertices of any triangle

• The set contain the drawing a line segments through a point A

• The set contain the sum of external angles of a polygon

If n(A) = n(B), then the two sets are called

• Null sets

• Equivalent sets

• Proper sets

• Subsets

If A ⊆ B, then AUB =

If set A = {1,2,4,6,7,9} and set B = {2,3,5,6,9} then find the B-A =

Let set A ={x : x is the element of word "FOLLOW"},

set B = {x : x is the element of word "WOLF"},

set C = {x : x is the element of word "FLOW"}

then these are the sets ?

• Equivalent sets

• Equal sets

• Both of these

• None of these
