PwC Associate Consultant interview questions

the problem they gave me was as follows; suppose you have a client in bangalore where it rains a lot, your client has to work outdoors everyday so if it rains on a particular day and he had not ordered for a tent beforehand then he has to pay up rs. 5000 for the tent but if he is sure that it will rain tomorrow then he can order for the tent in advance and pay 1000 only.
