A Hindu woman aged twenty years adopts a Hindu boy aged twenty years. The adoption is:

HAMA section 11(iv) requires a female adopting a male to be at least twenty-one years older than him. Both are twenty here, so that mandatory age gap fails. Section 10(iv) also normally restricts adoption to a person below fifteen unless an applicable custom permits otherwise, but such a custom would not cure the separate mandatory age gap. Section 5 makes a noncompliant adoption void; ordinary court leave cannot validate it.
