A couple of people got the answers right to yesterdays puzzle but I had to be harsh because the question asked for the logic in obtaining the answers which not everybody got right.
Onto todays puzzle then.
3 customers in a barbers shop need a haicut and a shave. There are 2 barbers working at the same speed. Each takes 15 minutes for a haicut and 5 minutes for a shave. They need to be off in a hurry. How quickly can they finish the work.

Customers are A, B + C.
Barber 1 cuts A’s hair whilst Barber 2 shaves B + C. He then shaves A. After 15 minutes A has had his haircut and A, B + C have all been shaved. Barber 1 then cuts B’s hair whilst Barber 2 cut’s C’s. Away in 30 mins.
???????????

1 minute.
The barbers sucked and wanked off the customers so they completely forgot about needing a haircut and shave and left.
