Trying to earn some extra cash, Roland decided to open a lemonade stall.

On his first day, he only managed to sell 16 cups of lemonade. The next day wasn't any better. It was raining really heavily and few people passed by his stall, so he only managed to sell 8 cups.

After reviewing his performance for the past 2 days, he decided to decorate his stand to make it look more attractive so that it will draw more people to his lemonade stand. His publicity stunt worked, for he managed to sell 33 cups of lemonade the next day.

Soon, word went round that there is a new lemonade stall selling cheap and nice lemonade. To Roland's surprise, sales was so good the next day that a whooping 89 cups of lemonade were sold. On the fifth day, Roland's good sales continued - he managed to sell 78 cups of lemonade.

It was soon obvious that Roland's sales were following a certain pattern.

A few days later, it was the first time after the 3rd day that Roland sold less than 40 cups of lemonade.

How many cups of lemonade did Roland sell that day?

On another of Chork's trips, he visited this small rural village called the Village of Uso. There were only 11 inhabitants in this village and the interesting fact about them is that they either always lie or always tell the truth. Upon reaching the village, Chork was warmly welcomed by the villagers who held a small party for him. As 2 of the villagers, Jessie and Kevin were sick, they were not present at the party. Nevertheless, Chork soon engaged himself with a conversation with the 9 other villagers:

"Say, out of the 11 villagers here, how many of you always lie?" Chork asked.

And Chork received a rather interesting reply from the 9 villagers present.

Andy's answer was 10.
Ben's answer was 7.
Colin's answer was 3.
Debbie's answer was 6.
Eric's answer was 11.
Fanny's answer was 5.

Previous Riki's Adventures: Puzzle 25

Riki the explorer bids you to follow him on his latest adventure again! Having secured the Everstone in puzzle 25, Riki feels more confident to go for another treasure hunting trip! Here's Riki, all packed and ready to go!

This time round, he is journeying into the depths of the Amazon rainforest to hunt for a rare tribal totem.

After a long trudge through the forest, Riki and you finally found yourselves before an ancient tomb. The tomb was well hidden amongst lush vegetation, and the stone tomb door was closed. Beside the tomb were some statues with letters engraved below them. Are they worth inspecting...?

Just then, the sharp-eyed Riki quickly spotted 10 levers near the tomb, labelled A-J from left to right. The levers look old from disuse. Still, both of you do not have any other clues to help you all along, so perhaps pulling one of these levers might help.

Riki was about to pull the lever nearest to him when he realised a similar message was engraved on each of the levers: "Be warned, intruders! Only one lever opens the door to the sacred chamber. The rest will bring you certain doom..."

Riki gulped. This is too risky to be left to chance.

Which lever should he pull?

Jack owns a paint shop. As business had been rather bad lately, he decided to clear his older stock by holding a promotion, where customers get to buy 3 cans of paint for the price of 2. He decided to package these cans of paint in a promotion box, which has a square base area. The cans of paint are perfectly cylindrical in shape and the diameters of the tin lids are all 10cm. He was pondering over how he should best fit the cans of paint in a square base box such that he would minimize the materials used for the box.

"How about this arrangement?" His friend suggested, "We just need a 20cm by 20cm square base box."

Jack gasped at the gaping hole in this arrangement. What a waste of space! Surely, there was a better arrangement to place 3 cylinders in a square base box?

To the nearest 0.01cm, what is the side length of the smallest square base that can fit the 3 cans of paint?

It was raining really heavily and 4 children, Armin, Bob, Chork and Don were stuck in school. They all wanted to get to the nearby MRT station but the route there was completely unsheltered and they all didn't want to get wet. Luckily, they had an umbrella. However, the umbrella could only shelter 2 people at any one time.

Armin takes 3 minutes to cover the distance from school to the MRT station (and vice versa). Bob takes 4 minutes. Chork takes 6 minutes and Don, who is rather slow, takes 10 minutes.

Now, their task is to get to the MRT station in the shortest time possible. However, note that when 2 people are sharing an umbrella, the faster person must accomodate the slower one and walk at his speed. Also, someone would have to bring the umbrella from the MRT station back to school so that the remaining children can continue using the umbrella.

What is the shortest time needed to get all 4 children to the MRT station, sheltered with an umbrella?

Previous hanjies: Puzzle 09 | Puzzle 16

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 43!

The emperor gathered the 100 wisest men in his empire and set them a task. If they manage to complete the task impressively, they will be generously rewarded.

The task is as such. The 100 men will be placed in a straight line and either a black hat or a white hat will be placed on their heads. Once they are lined up, they are not allowed to
(1) communicate amongst themselves
(2) turn back and look behind them
(3) remove the hat on their heads

The wise men will be able to see all the hats in front of him, but not the colour of his own hat or the colours of the hats behind him. They will, however, be able to hear the answers of the people behind them.

The king will then start with the man right at the back and ask: "What is the colour of your hat?" The wise man is only allowed to answer "black" or "white" and nothing more. After which, the man is not allowed to say anything more.

The king will the move on to the next man in line and ask the same question, all the way until he reaches the last man. Each man can only speak up when the king asks him the question and can say nothing more than "black" or "white". At the end of the whole task, the king will then tally the number of correct answers.

Before the wise men were lined up, they were allowed to get together and strategise, but they were told that the king would randomly line the men up.

What is the maximum number of correct answers that is GUARANTEED if the men strategise correctly?

On a recent trip to USA, Chork decides to go shopping with Thomas, Alexander and Benjamin. He had quite a lot of money with him but couldn't seem to find anything worth buying. At last, Chork spotted a shop selling odd gadgets and gizmos and was very interested in this spy kit which was on sale in the shop. Imagine all the mischief he could do with the kit!

He headed over to the counter to check the price of the spy kit and realised, to his delight, he had just enough money for 4 spy kits! He promptly paid for 4 spy kits and left the shop feeling very proud of his purchase.

Starting from the top left hand corner (S), you are to move to the bottom right hand corner (Y). However, there are a few rules which you must obey when moving through the grids:

1. Each time you make a move, you can only move to an adjacent grid, ie. one grid to the left, to the right, on top, at the bottom, or diagonally across.
2. You may not move to a grid which you have already stepped on previously.
3. When you trace the words of your route in the order which you take, you will form ONLY proper English words.

Riki the explorer was casually flipping through an ancient Egyptian text in his library when he read that the EverStone (supposedly the most beautiful, rarest and most expensive gem in the world) actually exists, contrary to the beliefs of many people who think that this gem is but a myth. Apparently the Everstone is located in a pyramid, where the body of a famous pharoah lies. In the book were several blurred paintings of the interior of the tomb:

Based on these pictures, the experienced adventurer was able to locate the tomb in which this mystical EverStone lies, and headed for the Egyptian tomb. Upon stepping into the pyramid, Riki noticed that the entrance of the cave was rather dark:

But the rooms within the tomb seemed surprisingly bright. He found many artifacts in the first room he entered, but could not seem to find the prized gem:

In another room, he spotted nothing but a rotting skeleton.

He headed to the last room, feeling rather hopeful, especially since the room was glittering gold. Unfortunately, he was disappointed with his findings in that room.

Surely the elusive EverStone is more than just a myth?

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!

What is the hidden picture?

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?

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?

Nick was doing target practice one day. Unfortunately, he wasn't a good shooter and his shots landed all over the board! After 25 shots, he decided to go for a break. Here's a layout of his shots on the board:

His sister, Sally came over, took a look at the board and observed: "You are not a bad shooter actually - all but one of your shots follow a pattern!"

NOTE: In the diagram above, the shots are not labelled in order of how they were fired. The numbering is only for referencing to the first diagram so that you can point out a particular shot more easily.

Which shot (1-25) is the odd one out?

In this room, there are 2006 opened lockers, numbered 1-2006. On Day 1, Ella decides to close every second locker. On Day 2, she heads to every third locker and opens it if it is closed and closed it if it is open. On Day 3, Ella repeats her action of day 2 on every fourth locker (ie open it if it is closed and closes it if it is opened.)

She repeats this action on subsequent days, ie. on day n, she heads to every (n+1)th locker and opens it if it is closed and closes it if it is opened. On Day 2005, she heads to the 2006th locker and shuts it and completes her cycle of actions. (At last she can take a break!)

How many lockers are open at the end of day 2005?

After looking at the paper for the one millionth time, Hannah sighed, crumpled the paper and tossed it away. Surely YOU won't be giving up on the very first Chork's puzzle too? (:
