91. SUPERBOWL Nine members of the American
football team were lined up waiting to take their place on the playing field.
If two players in the top row changed places with two players on the second
row, then the number reading across the jerseys of the players on the bottom
row would be exactly a fifth of the number across the five players on the top
row. Can you work out which two players on the top row, and which two players
on the second row, need to change places for this to occur? |

of being born, where it was the only inhabitant. There are now a total of 98
newts in this new pond. If all newts survived, and none had moved away during
the last year, how many had moved away over the six years? |

94. IN THE PARK A square park is
denoted by its North, East, South and West sides. It has two seats on each
side. The seats north and south sit a maximum of four people each and the
seats east and west sit a maximum of three people each. Two seats are full.
One seat has no one sitting on it. No seats next to or opposite each other
have the same number of people sitting on them. The total of people in the SE
corner equals the total of people in the NW corner, but none of the seats has
the same number of people on them. The total of people in the NE corner is
double that in the SW corner. How many people are sitting on the seats in the
park? |
