 You have 8 balls. All are identical except one is slightly heavier. You have a balance. What is the minimum number of weighings required to find the heavier ball?5 Answers2Min answer can be 2 if you get luck and pick 2 and weigh and see a diff. Else the general answer is =3. 1. div 4 and 4 and weigh, 2. take the heavier side, div in half, 2 and 2 and weigh, 3. take heavier side and weigh/compare the two.2: Start by weighing 3 and 3. Leave 2 off to the side. There are 3 possible outcomes: Case 1: The balance indicates that the piles of 3 are of equal weight. In this case, we know that one of the two off to the side is the heavy one. Weigh them against each other to determine the heavy one. Total weighings: 2. Case 2: The left pile of 3 is heavier. We know that one of the three balls on the left side is the heavy one. Randomly select two of the balls and keep the third off to the side. If the two selected balls weigh the same, we know that the one on the side is the heavy one. Otherwise, the heavier of the two balls is the heavy one. Total number of weighings: 2. Case 3: Without loss of generality, look at the balance from the other side and refer to case 2. In all cases, we find the heavier ball in a maximum of 2 weighings.Show More ResponsesHow will this work, if one of the ball is lighter? and what if the number of balls is increased to some other even number, such as 10. What happens if the total number of balls or what ever is an even number such as a 7?minimum number of time is 1. You may be able to find it in first time itself. Maximum is 4

 What is a "matching network" really trying to match?3 AnswersImpedance to provide for maximum transmission of power.It is trying to match both the real and reactive source or load impedance to the system Zo, usually. Doing so provides maximum gain, and in a purely linear system maximum power transfer Matching networks may also be quite commonly used to match the system Zo (say 50 Ohms) to the load line of a non-linear device such as a power amplifier, or just as similarly to match tot he optimum noise impedance of an LNA. In these cases a perfect match is not desired, as maximum gain is not the goal, but rather maximum efficiency or lowest noise figure.You want the real parts to match and the reactive components to cancel if you want max power transfer

 I expected questions, but not a grade school IQ test. Maybe a personality test would be more appropriate.2 AnswersAs someone who was once a part of the interview process you are not taking a test to be accepted. It's a front. You were probably eliminated because of a stereotype or because you didn't fit their appearance standards. For example, weight, gender etc...I disagree with the above comment. With the number of comments to interviews you have made saying the same thing, it is obvious that you have an ax to grind. Peddle your conspiracy theories somewhere else.
