Explanation

His tattered coat needs mending means اس کے پھٹے ہوئے کوٹ کو ٹھیک کرنے کی ضرورت ہے

"Tattered" is the correct adjective meaning torn or worn out.

Explanation

"Old" starts with a vowel sound, so we use "an" before it.

Correct sentence: "Is your mother working in an old office building?"
