weigh the two groups of three against each other. If equal, weigh the group of two to find the heavier. If one group of three is heavier pick two of the three and compare them to find the heaviest.
What is the fewest number of weighings You need to find the odd ball out?
Each weighing weighs one ball. The minimum number of weighings to identify a difference is two, i.e the first two balls are different in weight. The third weighing will confirm which of the previous two is part of the set of eight balls with the other being the odd one out.
Can you have one epididymis bigger than the other?
It’s normal for one testicle to be slightly larger than the other, and for one to hang lower than the other. You should also know that each normal testicle has a small, coiled tube (epididymis) that can feel like a small bump on the upper or middle outer side of the testicle.
Which is the correct answer to the balance puzzle?
There are three possibilities: 1.a) The same side that was heavier the first time is still heavier. This means that either the coin that stayed there is heavier or that the coin that stayed on the lighter side is lighter. Balancing one of these against one of the other ten coins reveals which of these is true, thus solving the puzzle.
Which is the lighter coin in the balance puzzle?
For the third attempt, weigh two of these coins against each other: if one is lighter, it is the unique coin; if they balance, the third coin is the light one. 1.c) Both sides are even. This means that one of the three coins that was removed from the heavier side is the heavy coin.
Which is heavier a coin or a coin not on the balance?
If the two coins balance then the third coin not on the balance is the odd one out and it is heavier. 2.c) The three remaining coins balance. In this case you just need to weigh the remaining coin against any of the other 11 coins and this tells you whether it is heavier, lighter, or the same.
What happens if two of the three coins balance?
Take two of those three coins and weigh them against each other. If the balance tips then the heavier coin is the odd one out. If the two coins balance then the third coin not on the balance is the odd one out and it is heavier. 2.c) The three remaining coins balance.
