No I dont know anyone who has undergone this certification, even I tried finding out but was unable to search for someone within such a short time. Try texting those who already working in this position at Merkle on Linkedin. Moins

### You have 8 marbles and a balance scale. One marble weighs more than the others, but you don’t know which one. How can you identify the heavier marble using only two weighs of the balance scale?

2 réponses

We put 3 marbles on each side of the scale for a total of 6 marbles that are being weighed. We leave 2 marbles off the scale. Then, we compare the 6 marbles… There are two possible outcomes: If one side is heavier than the other then we only have 3 marbles left. Then, in the second weighing, we can compare 2 of those 3 marbles to each other. If they are the same weight, then the 3rd is the heaviest. If one is heavier than the other, then we’ve succeeded in just two weighings. If, when comparing the 6 marbles, we find that both sides are equal, then we know that the heaviest marble has to be in the 2 marbles that are not on the scale. This means that we only have to compare on those 2 remaining marbles and we have the heaviest marble in only two weighings. Moins
