Brain workouts

[ufo_investigations]

Welcome to brain workouts. For those of you tired of my ufo claims here is some exercises for your brain. The first person to submit the answer and an explanation of how you worked it out is the winner. Simply guessing which one it is wont cut it. You must explain how you came to the conclusion.

Puzzle #1

A wine merchant has six barrels of wine and beer containing: 30 gallons; 32 gallons; 36 gallons; 38 gallons; 40 gallons; 62 gallons

Five barrels are filled with wine and one with beer. The first customer purchases two barrels of wine; the second customer purchases twice as much wine as the first customer.

Which barrel contains beer?

Puzzle #4

What number, when you multiply it by 5 and add 6, then multiply that result by 4 and add 9, gives you a number that, when you multiply it by 5 and subtract 165, gives you a number that, when you knock off the last 2 digits, brings you back to your original number?
