An electronic weighing machine is provided to you and you are allowed only one chance of weighing on it.
How will you find out which box has defective balls ?
Hint:
Let us simplify boxes by naming them from 1 to 10.
Now the trick here is to pick different number of balls from different boxes. So to simplify things, we will pick balls corresponding to box number.
Thus, pick 1 ball from Box 1, 2 balls from box 2, 3 balls from box 3 and so on. You will have 55 balls altogether. Now, put them all in the balance.
If all balls were weighing accurate 10 grams, the total weight of the 55 balls would have been 550 grams. But one of the box must have had the defective balls.
Suppose if the defective balls were in box number 2, then the total weight will be 2 grams less than 550. If the defective balls were in box 8, the total weight will be less than 8 grams from 550. In this way, you will be able to identify which box has the defective balls. Did you answer this riddle correctly?
YES NO

Husband, Wife And Mailman Riddle
A married couple went to the hospital to have their baby delivered. Upon their arrival, the doctor said he had invented a new machine that would transfer a portion of the mother's labor pain to the baby's father. He was asked if they were willing to try it out. They were both very much in favor of it.
The doctor set the pain transfer to 10% for starters, explaining that even 10% was probably more pain than the father had ever experienced before. However, as the labor progressed, the husband felt fine and asked the doctor to go ahead and kick it up a notch. The doctor then adjusted the machine to 20% pain transfer. The husband was still feeling fine. The doctor checked the husband's blood pressure and was amazed at how well he was doing. At this point, they decided to try out for 50%. The husband continued to feel quite well.
Since the pain transfer was obviously helping out the wife considerably, the husband encouraged the doctor to transfer all the pain to him. The wife delivered a healthy baby with virtually no pain. She and her husband were ecstatic. When they got home, the mailman was dead on the porch. What happened?

Hint:
Dunsinane
Macduff and the opposing forces camouflage themselves with branches from Birnam Forest. Dunsinane is a peak of the Sidlaw Hills, in the parish of Collace, Perthshire, Scotland, 8 m. N.E. of Perth. It is 1012 ft. high, and commands a fine view of the Carse of Gowrie and the valley of the Tay. Its chief claim is due to the association with Birnam Wood (about 12 m.
