Puzzle 53
I recently gave a new carriage clock to my friend for a very special birthday.
However, as usual with my presents, it was quite useless as it loses 6 minutes every hour.
I set it using my own accurate clock at midnight and the clock now shows 10:12am.
I know that it stopped 2 hours ago, so what is the correct time now?

Hint
How many clock minutes pass in a real hour?
Answer
1:20pm.
Reasoning
The clock now shows 10:12am, so we know that 10 x 60 + 12 = 612 clock minutes have passed.
Since the clock is losing 6 minutes every hour, for every real hour that has passed the clock will show 54 minutes.
So, 612 ÷ 54 ≈ 11.33 real hours have passed.
This equals 680 minutes, which is 11 hours and 20 minutes = 11:20am.
The clock stopped 2 hours ago, therefore the time must now be 1:20pm.

ru- = run
How many of the following words are not complete words? Proper nouns and names are not allowed.
team

Each of these words can have a letter added, and then be rearranged to make a new 5-letter word.
For example: DENY + B = BENDY (not part of the answer!).
If the 7 added letters are an anagram of CHEMIST, what are the new words?
deny
mail
exit
gosh
city
newt
type

Frankie came second in croquet, the 15-year-old won, Dale beat the 18-year-old, and the 19-year-old came third.
Emery is 3 years younger than Glen.
The person who came last in chess came third in croquet, and only one person got the same position in both games.
Can you find the ages of the people and their positions in the two games?

Hint
How old could Glen be?
Answer
Name Age Chess Croquet
Dale 15 3 1
Emery 16 1 4
Frankie 18 2 2
Glen 19 4 3
Reasoning
The possible ages are: 15, 16, 18, 19.
Breaking the clues down, and numbering them:
Frankie beat Glen in chess.
Dale came third (chess).
The 16-year-old won (chess).
Frankie came second in croquet.
The 15-year-old won (croquet).
Dale beat the 18-year-old (croquet).
The 19-year-old came third (croquet).
Emery is 3 years younger than Glen.
The person who came last in chess came third in croquet.
Only one person got the same position in both games.
By (4), Frankie came 2nd in croquet.
Name Age Chess Croquet
Dale
Emery
Frankie 2
Glen
By (2), Dale came 3rd in chess.
Name Age Chess Croquet
Dale 3
Emery
Frankie 2
Glen
By (8), Emery is 15 or 16, and Glen is 18 or 19.
By (9), the person who came 4th in chess, came 3rd in croquet, and by (7), they are 19. This can't be Dale (3rd in chess), or Frankie (2nd in croquet), or Emery (aged 15 or 16), so it must be Glen.
Name Age Chess Croquet
Dale 3
Emery
Frankie 2
Glen 19 4 3
By (6), Dale can't have been 4th in croquet, so must be 1st. Leaving Emery in 4th.
Name Age Chess Croquet
Dale 3 1
Emery 4
Frankie 2
Glen 19 4 3
By (10), only one person got the same position in both games, this can't be Emery 4th in both (as Glen is already 4th in chess), so must be Frank, 2nd in both. Leaving Emery 1st in chess.
Name Age Chess Croquet
Dale 3 1
Emery 1 4
Frankie 2 2
Glen 19 4 3
By (3) and (5) we know the ages of the winners in each competition, and Frankie is therefore 18.
Name Age Chess Croquet
Dale 15 3 1
Emery 16 1 4
Frankie 18 2 2
Glen 19 4 3
