1 Answer

Answer :

If the girls had been on a standing train, the first girl's calculations would have been correct, but their train was moving. It took 5 minutes to meet a second train, but then it took the second train 5 more minutes to reach where the girls met the first train. So the time between trains is 10 minutes, not 5, and only 6 trains per hour arrive in the city.

Once upon a time, in a temple, there were three deities: Truth, Lie and Wisdom. The Truth Deity always told the truth. The Lie Deity always told the lie. The Wisdom Deity sometimes told the truth, sometimes told the lie. Unfortunately, those three deities looked exactly the same, so that no one could distinguish them. One day, a sage came by and he differentiated them by the following trick: He asked the deity sitting on the left: 'Who is the middle deity?'- 'Truth', said the deity. He asked the deity sitting in the middle: 'Who are you?'- 'Wisdom', replied the deity. He asked the deity sitting on the right: 'Who is the middle deitie?'- 'Lie', the deity answered.How could the sage distinguish the three deities? -Riddles
