The other IAS question and find the solution with a challenge from Tapasya...


The Barbershop
A traveler arrives in a small town and decides he wants to get a haircut. According to the manager of the hotel where he's staying, there are only two barbershops in town — one on East Street and one on West Street. The traveler goes to check out both shops. The East Street barbershop is a mess, and the barber has the worst haircut the traveler has ever seen. The West Street barbershop is neat and clean; its barber's hair looks as good as a movie star's.
Which barbershop does the traveler go to for his haircut, and why?

Which Way?
Once a boy was walking down the road, and came to a place where the road divided in two, each separate road forking off in a different direction.
A girl was standing at the fork in the road. The boy knew that one road led to Lieville, a town where everyone always lied, and the other led to Trueville, a town where everyone always told the truth. He also knew that the girl came from one of those towns, but he didn't know which one.
Can you think of a question the boy could ask the girl to find out the way to Trueville?

Outsmarting the Donkey
Amir tied two sacks of salt to the back of his donkey and headed for the market to sell the salt. On the way, Amir and the donkey passed a stream. The donkey jumped in to cool himself. As a result, much of the salt dissolved into the water, ruining the salt for Amir but improving matters for the donkey because his load became much lighter. Amir tried to get to the market on the following days, but the donkey always ruined the salt. Finally, Amir decided to teach the donkey a lesson. He once again set out with the donkey and the two sacks.
What did Amir do differently this time so that after that day the donkey stopped taking a swim?
