$A=\{a, e, i, o, u\}$ અને $B=\{a, b, c, d\}$ લો. $A$ એ $B$ નો ઉપગણ છે ? ના (શા માટે ?). $B$ એ $A$ નો ઉપગણ છે? ના (શા માટે ?)

$A=\{a, e, i, o, u\}$ and $B=\{a, b, c, d\}$

( $i$ ) For a set to be a subset of another set, it needs to have all elements present in the another

set.

In set $A,\{e, i, o, u\}$ elements are present but these are not present in set $B$

Hence $A$ is not a subset of $B$.

(ii) For this condition to be true, are elements of sets $B$ should be present in set $A$

In set $B,\{b, c, d\}$ elements are present but these elements are not present in set $A$

Hence $B$ is not a subset of $A$
