1) This is a simple classic. Peter is cleaning up after a marathon poker party and feels the need to smoke. He finds 29 cigarette butts in various receptacles. He recalls that four butts yield enough tobacco for one cigarette and begins to build cigarettes from the butts. He smokes as many cigarettes as he can make. How many butts will remain at the end of the clean-up?

 

2) Another simple classic. Five men, namely Anderson, Baker, Campbell, Draper and Emory dined with their wives at a circular table. Men and women alternated, and husbands and wives sat three places apart (ie two other diners sat between husband and wife in every case). Mrs Campbell was on Mr Anderson’s right. Mr Campbell sat two seats to the right of Mr Emory (ie one intervening diner). Mrs Baker was two places to the left of Mrs Emory. Who sat on Mrs Anderson’s left?

 

 

The answers to March’s puzzles were supplied in the March issue.

 

Here are the answers to this month’s puzzles:

 

1) 29 butts produce seven cigarettes with one butt left over. The seven cigarettes produce seven butts, which makes eight in all. These in turn yield two cigarettes, which produce two butts to be disposed of.
