Chork's Puzzle 19

Difficulty Rating: 5

Jon set off from his home to his office on his brand new car, driving at a constant speed of 66km/h. After driving for 16km, Jon realises that he left an important document at home and checks his watch to see if he has enough time to drive back home to collect the document. When he glanced at his watch, the minute hand was exactly over the hour hand.

Assuming at the time Jon set off, it was a whole number of minutes (ie. it just reached a particular minute and not halfway into the minute),

What time did Jon set off?

Previous hanjies: Puzzle 09

Hanjie is a fascinating Japanese picture puzzle. Each puzzle consist of a grid of empty white squares. At the bottom and right hand side of each puzzle are a set of numbers which dictate how many cells in that row or column must be coloured in. Shading the grid according to this set of numbers will reveal a picture! (:

Now, if the bottom of a column says "5", it means that in that column, 5 consecutive cells are coloured. If a row says "2, 3, 4", it means that in the row, there are 3 discrete sets of cells to be coloured, and each set of cells are 2, 3, 4 cells in length, and in that order. There must be at least one empty cell between each set of cells to distinguish between them (ie the 2, 3, 4 cannot be joined together to form a long 9 cell set).

Using logic, you should be able to deduce which cells in a particular row or column should be coloured in. You may, however, need to use cross referencing with different rows and columns or elimination.

And here's the hanjie for puzzle 16!

One festive season, Andrew was enjoying a quiet time at home when 4 men barged in, nabbed him and forcefully brought him away. "Where are you taking me to?" asked Andrew in terror.

"Happiness to the global ecosystem!" barked one.
"In a remote location in a barn stall!" screamed another.
"I am fantasizing about a colourless holiday!" howled a third.
"Small male percussionist," growled the last.

And Andrew knew all was lost.

Where were the men taking him to?

Since I have been getting requests to post puzzles of different nature, I have decided to create a SPOT THE DIFFERENCE puzzle! (: In the first picture, I present to you a scene on my table:


In the second picture, it is supposed to be the same scene of my table, taken from a slightly different angle.


However, if you are quick enough, you would have realised that besides being taken from a different angle, there are some changes to the things on my table - in fact 9 in total!

Unlike other puzzles where you have to post the full solution, you can post partial solutions to this puzzle (ie only some of the 9 differences) and let others finish it up for you!

Can you spot the 9 differences?

Once upon a time, there lived three little pigs. The three little pigs lived in the depths of a forest, where they each built a house of their own.

The youngest pig imported the finest straws from Australia, and built a snuggly straw house. The middle pig imported the sturdiest timber from Finland, and built a rustic timber house. The eldest pig, being the most practical, imported the best bricks from Italy and built a strong brick house.

The pigs had a merry time in the forest until a big bad wolf walked by their houses one day. Feeling nasty, the big bad wolf set their houses on fire, which instantly triggered the fire alarms of the houses. The fire alarm scared the wolf away, but also jolted the pigs awake from their beauty sleep. Seeing the blazing flames, they panicked and quickly phoned for help.

While waiting for help to arrive, the pigs tried to put out the fire on their own, but to no avail. The fire just seemed to get fiercer and wilder. At last, the pigs were delighted to hear the sounds of sirens. Aid had arrived! Leading the way was a police car, followed by an ambulance.

Which house did the ambulance try to put the fire out first?

Chork's Puzzle 08

Tom decides to play a coin flipping game with Mary. He bets that heads will turn up when he flips the coin.

On the first game, he starts off with a stake of $1. If he loses, he doubles his stake in the next game, and for subsequent games, he will continue to double his stake until he eventually wins. However, at any point of time should he win the bet, in his next game, his stake will return to $1 again.

Tom continues playing in this manner (ie doubling stakes for the next game if he loses, or decreasing his stake back to $1 if he wins) for 200 rounds. Tom prayed fervently for a heads to appear on each toss, but unfortunately, he is rather down on luck, and tails seem to show up more frequently than usual. In fact, on the 200th round, Tom only managed to toss his 16th heads.

"Looks like I'm not so lucky today," mutters Tom, and he decides to quit the game on the 200th round.

How much did Tom lose?
