Grid Based Puzzle

admin — Mon, 13 Sep 2010 08:18:58 +0000

Friends based on the emails I am getting I think most of you like creative and interesting logical puzzles. So I am presenting another very interesting grid puzzle one for you.

Grid Puzzle

Below is a very special grid, around each shaded number are 8 white squares. However, each white square should have a number from 1 to 7. Once filled in, these 8 numbers will sum to the shaded number. In addition, once completed correctly, no row nor column will contain a duplicate number within a white square. For example, the top row may be 5 6 4 2 3 1 7, etc. hence no digit repeated (similar to Sudoko)

Try to fill all the blank spaces. Leave your answers below by writing the numbers row-wise.

Time Measurement Riddle

admin — Tue, 07 Sep 2010 20:58:12 +0000

After quite a few days I am posting a riddle. I assure you it's very interesting. Though it may seem a little difficult when you first read it, maintain your cool and ponder over it again.

Suppose you have ten threads and a lighter. If a thread is lighted, it will burn for exactly one hour. The threads do not burn at constant speed, in other words it can happen that the first half of the thread is burned in 15 minutes, while the remaining part will take three quarters. How can you measure exactly 45 minutes using these threads, and what is the minimum of threads you need for this?

If you need any clarification, leave your queries as comment.

Most Difficult Riddle: One of my friend have forwarded me this mentioning the background. It claims that this mathematical puzzle was created by Einstein. Though we don't vouch for this claim but in any case it is very interesting to solve this. So guys go ahead and solve. We are ready to give the solutions too, if you all fail to solve it. But hope that's not the case. All the best!

Albert Einstein created this riddle in the late 1800s, and claimed that 98% of the world population couldn't solve it. It is a good brain exercise. Here it is:

- In a street there are five houses, painted five different colors.

- In each house lives a person of different nationality.

- These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.

Einstein's riddle is: Who owns the fish?

1. The British man lives in a red house.
2. The Swedish man keeps dogs as pets.
3. The Danish man drinks tea.
4. The Green house is next to, and on the left of the White house.

Fruit Seller’s Paradox

admin — Wed, 03 Mar 2010 04:16:44 +0000

Fruit Seller's Paradox- Each of two apple women had 30 apples for sale. The first sold hers at the rate of 2 for a nickel, the second at the rate of 3 for a nickel. At the end of the day their respective receipts were 75 cents and 50 cents, or $1.25 in all.

The next day the women decided to do business together, so they pooled their 60 apples and sold them at the rate of 5 for a dime (2 for a nickel plus 3 for a nickel). Upon counting their joint receipts at the end of the day they were dismayed to find that they had only $1.20. They searched all about them for that other nickel, and wound up by bitterly accusing each other of having taken it. Where was it? (1 Nickel = 5 Cents)

Windy Flight Paradox

admin — Sun, 21 Feb 2010 17:22:15 +0000

A plane makes a trip from New York to Washington and back to New York. Call the distance between the two cities 200 miles and the speed of the plane 100 miles per hour. Then the time required for the round trip, ignoring stops, is 4 hours. Now suppose there is a strong wind which blows throughout the entire trip with the same speed and in the same direction-from New York directly toward Washington, say. Then the tail wind on the way south will speed up the plane to the same extent that the head wind will retard it on the way north.

Windy Flight Paradox

In other words, both the average speed of the plane and the time for the round trip will be independent of the speed of the wind. But this means that the plane can still make the trip in 4 hours even though the speed of the wind is greater than that of the plane, in which case the plane would be blown backward on the trip from Washington to New York!

Puzzling Puzzle

Who should be the Boss?

A large business firm was once planning to open a new branch in a certain city, and advertised positions for three clerks. Out of a number of applicants the personnel manager selected three promising young men and addressed them in the following way : "Your salaries are to begin at the rate of $1000 per year, to be paid every half-year. If your work is satisfactory, and we keep you, your salaries will be raised.

Which would you prefer, a raise of $150 per year or a raise of $50 every half-year?" The first two of the three applicants eagerly accepted the first alternative, but the third young man, after a moment's reflection, took the second. He was promptly put in charge of the other two. Why? Was it because the personnel manager liked his modesty and apparent willingness to save the company money?

Weird Brain Teaser...isn't it?

A certain sportsman, experienced in shooting small game, was out on his first bear hunt. Suddenly he spotted a huge bear about a hundred yards due east of him. Seized with panic, the hunter ran out directly away from the bear, but, in his confusion, due north. Having covered about a hundred yards, he regained his presence of mind, stopped, turned, and killed the bearwho had not moved from his original position-by shooting due south. Have you all the data clearly in mind? Very well, then what color was the bear?

Teasing Brain Teaser!!

I met Sweety first time in a marriage party in Kolkata. We exchanged our phone numbers and decided to meet each other soon. When she rang up and invited me to her house, she decided to tease me.

This is how she gave me the number of her house on a particular street:

“I live in a long street. Numbered one the one side of my house are the houses one, two, three and so on. All the numbers on one side of my house add up to exactly the same as all the numbers on the other side of my house. I know there are more than 50 houses on that side of the street, but not so many as 500”

Can you help me find Sweety’s House number?
