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.

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?

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.
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?"
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?
