Question

Let A be the set of multiples of 3 less than 20 and B be the set of multiples of 4 less than 25, then which of the following statements is true ?
1) A and B are equal sets
2) A and B are equivalent
3) A and B are disjoint
4) None of these

Please explain the reason also​

Answer 1

Answer:

$\huge\boxed{\fcolorbox{blue}{orange}{HELLO\:MATE}}$

#Stay home. stay safe

Clearly from the given data

Set A = {3, 6,9,12,15,18}

and

SetB = { 4,8,12,16,20,24}

Here the cardinal number of both the sets are equal.

Therefore A & B are equilavent sets.

This is so, because two sets are said to be equivalent if they have sane cardinal number.

Answer 2

Answer:

1)A and B are equal sets. ≈»is the true statement.
