Question

If set A = {x : x is even} and B = {x : x is a multiple of 4}, then A) A ⊂ B b) A & B are disjoint c) B ⊂ A none of these

Answer 1

$A = \{x : x \: is \: even \} \\\implies A = \{ 2,4,6,8,10,\ldots \}$

$B = \{ x : x \: is \: a \: multiple \: of \: 4 \} \\\implies B = \{ 4, 8,12,16,20,24, \ldots \}$

/* Each element of set B is element of set A */

Therefore.,

$\green { B \subset A }$

$Option \: \pink{ ( c ) } \: is \: correct$
