Mega Shortcut - The 'Only' Trick:
When you see 'only son' or 'only daughter', that person becomes the direct link:
• 'Only son of my father' = Myself (if male) or My brother
• 'Only daughter of my mother' = Myself (if female) or My sister
Another Power Trick - Reverse Method:
Start from the answer choices and work backwards. This saves 30-40% time in complex problems.
