## Puzzle One

Mikayla has to visit towns A, B and C in any order. Some new roads are now available for connecting these towns with her Home as shown on the diagram below. How many different routes can she now take starting from Home and returning to Home, going through towns A, B and C in any order, but not more than once through each and not travelling any road twice on the same route?

Solution:

CW (16) + CCW (16) = 32 routes

Going clockwise (CW) from Home through towns C, B & A. there is now a two-road option to C, followed by a two-road option to B, a further option of a two more roads to A, and finally a two-road option back to Home.. Thus, the number of different routes that Mikayla can take going CW is equal to 2 x 2 x 2 x 2 = 16 different routes
Going counter-clockwise (CCW) from Home through towns A, B & C. there is now a two-road option to A, followed by a two-road option to B, a further option of a two more roads to C, and finally a two-road option back to Home.. Thus, the number of different routes that Mikayla can take going CCW is equal also to 2 x 2 x 2 x 2 = 16.

## Puzzle Two

Sue has 6 siblings. They were all born 2 years apart. The youngest, Rose, will be 7 years old next year while Sue is the oldest. What is Sue’s present age?

Solution:

Rose, the youngest sibling, is presently 6 years old. It is said that each sibling was born 2 years apart, and in total, there are seven children (Sue and his 6 siblings). So Sue’s age is: 6 + 2 + 2 + 2 + 2 + 2 + 2 = 18 yrs. old

## Puzzle Three

There is a barrel with no lid and some wine in it. “This barrel of wine is more than half full,” says the woman. “No, it’s not,” says the man. “It’s less than half full.” Without any measuring implements and without removing any wine from the barrel, how can they easily determine who is correct?

Solution:

Tilt the barrel until the wine barely touches the lip of the barrel. If the bottom of the barrel is visible then it is less than half full. If the barrel bottom is still completely covered by the wine, then it is more than half full.
