Charlotte's Adventure

Charlotte's* baby Joy flew in the air and got stuck on the other side of the road.

Luckily, a fifteen feet long ladder is placed across the street such that while its base is at one edge of the street its top rests against the opposite wall at a height of nine feet. Similarly, another ladder, twenty feet long, is placed resting across the other side-wall so that the two ladder cross each other.

Charlotte wants to use the ladder to cross the street.

How long will Charlotte take to accomplish the crossing assuming that he covers one foot in ten seconds ?

* Charlotte is the name of the barn spider

Help Me Cross the River

I have been traveling across the country with my wolf, a sheep, and sack of grain. We have traveled a long way and finally reach the river. The ferry is broke and current is too strong to wade across.

The ferryman tells me I may use the smaller raft, but it cannot hold much weight. Only two items may be on the raft at any time.

I must get across with my wolf, the sheep, and the sack of grain. The four of us cannot all be on the raft at once, so I must make the trip across in stages.

If I leave the sheep with the grain, it will eat the grain. If I leave the wolf with the sheep, it will eat the sheep.

How do I get all items and myself across the river without losing any of the items?

Spot on the Table

A boy, recently got home from school, wished to give his father an exhibition of his precocity. He pushed a large circlular table into the corner of the room, so that it touched both walls, and he then pointed to a spot of ink on the extreme edge.

"Here is a little puzzle for you, father," said the youth. "That spot is exactly 8 inches from one wall and 9 inches from the other. Can you tell me the diameter of the table without measuring it?"

The Riddle Poem

You're looking for a one-word answer to this riddle

Leave the tea and get me a pot,
And I'll devise a devious plot.
Ideas are fixed firmly in my mind,
As I lay in my bed, my thoughts entwined,
I cannot sleep, so I take a drink,
Breath in the air, I'm on the brink
This story will be the best seller yet,
The sweet smell of success I'll surely get

It Could Happen To You

Michael was going to his hometown to see his mother who had fallen ill suddenly. He had been driving through the hills since mid-night. The day had just broken and he was happy to get a view of the country he was passing through. Suddenly he had to jam the brakes when a missing culvert alerted him. He did managed to stop just in time and was glad he had not driven over it during the hour of darkness. Perhaps the culvert had been washed away by rain the previous evening.

After he got over the initial shock, he went about inspecting the site with the idea of finding a diversion but due to the nature of the terrain, any bypassing seemed impossible. It had to be over the missing culvert; but what chances was there of making it, he wondered !

Three meters of the road was not there and the car was five meters long. He noticed that there was a gradual climb of one in ten just before the culvert and that the road on the far side was level with the near end of the culvert. He estimated that his car could pick up a speed of atleast seventy two kilometers an hour just before the jump. It occured to him that he could make it. He had been known to be a brave man; moreover the love for his mother inspired confidence.
"It's now or never," he thought and off he went.

Did he make it ?

The Mirror does Lie

Imagine, you are standing in front of a mirror, facing it. Raise your left hand. Raise your right hand. Look at your reflection.

When you raise your left hand your reflection raises what appears to be his right hand. But when you tilt your head up, your reflection does too, and does not appear to tilt his/her head down.

Why is it that the mirror appears to reverse left and right, but not up and down?

What is it ?

I could not resist. It was just sitting there in the store, silent, waiting. Every day I would stop and look at it, with the freakish fascination of bystanders at the scene of an accident.

It kept calling to me. I kept coming back to it.

A friend was wondering what was wrong with me. "Why do you look at that? You don't even like it!". How could I explain to him the indifferent compulsion that drew me again and again? How could I explain that words such as "like" became meaningless, hollow noise when compared to the universe of my fascination?

And then one day, I bought it: ?

Timeless puzzle

"Boss."
"Yes Tom."
"How long did you take to get home from the office?"
"Well, when I started from the office the hour hand and the minute hand were together and when I got home they had just about got exactly opposite each other."

"And Boss."
"Go on. Tom"
"Had you left the office when the two hands were exactly opposite each other, you would have got here exactly when the two met."

"I don't know, Tom"

Sharp Tom did manage to get the Boss muddled up, but was he right ?

Alice said to Bob "Give me one of your pieces so that we shall both be carrying the same number of pieces"

"No" said Bob, proudly wanting to display his strength. "Give me one of yours and I shall be carrying twice your weight."

How?

The Billionaire Club

Bill Gates, and Warren Buffett were sitting together in the Billionaire Club with 56 and 52 billion dollars respectively. Suddenly Gates hit upon a new idea.

"We'll throw six dice together," he said.
"If we get two pairs I win, otherwise I lose."
"But what about four or more dice show the same digit?" enquired Warren.
"That makes two pairs; so that too gives me a win."
"And if only three dice have the same digit?"
"You win in that case because it does not make two independent pairs."

"Each games of chance will cost 2 Billion dollars to the looser" added Gates. "You want to play?"

Warren, a little confused calls YOU and asks "Who is more likely to win in this scenario?" What will you say ? Assuming they do play, how many games they can play at the least ?
