BRAIN TEASER!
There are ten boxes containing some balls. Each of the ball weighs exactly 10 grams. One of those boxes has defective balls (all the defective balls weigh 9 grams each). 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?
◆ Proper explanation needed.

Hey Friend!!!
Here is your answer.
To find it I will have two conditions.
★ If luck helped me. I will pick up a ball from any box and weigh it. If it will be of 9 gram then I will know it have defective balls.
★ But if luck didn't helped me and it weighted 10 grams then I shall compare the weight of the ball with other balls picking one by one from rest of the box. The ball which will be felt less heavier than the ball which I weighted then only I will come to know that the balls in that box are defective .
Thank You!!!
Hope this will be helpful for you.

There is no way you can measure and surely can predit which box contains the defective balls. It will at least take 3 such measurement and if lucky 2 will be enough. weighing something by hand and then guessing which one is heavier is not at all a scientific technique. If you can measure that little difference of weight by hand then why are you taking the pain of bringing the weighing machine into the question.
