How do you get to know if the auto-waala is fooling you?

On the journey, if the auto-waala makes two consecutive right turns or two consecutive left turns, then there might be something fishy.... though not necessarily... if he makes 3 consecutive same turns then 99% of the time, he thinks you are a dupe!!

How do you get to know the age of a lady?

If she passes by your city in train, then go meet her and secretly view her age from the reservation list stuck outside the compartment. Nowadays, people buy e-tickets and hence unlike few years ago, ladies cannot mention their incorrect age on the ticket, because they have to produce a photo-id proof.. which mostly contains the date of birth.
