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?

Redmonds Runs Riddle
During a baseball game in Redmond, John was Redmonds lead-off batter. There were no substitutions or changes in the Redmond batting order at all during the nine-inning game. John came to bat in every inning. What is the least number of runs Redmond could have scored?
Hint:
Zero. In the first inning John and the next two batters walk and the next three strike out. In the second inning, the first three walk again, which brings John back to bat. But each runner is caught off base by the pitcher, so John is back at the plate at the start of the third inning. This pattern is now repeated until the game ends with no joy in Redmund, even though the mighty John never once strikes out. Did you answer this riddle correctly?
