12 Identical Balls
I have a doubt if this is right. There are 12 balls out of which 11 are identical in mass. Take the first one. Keep it on one side of a balance. Then in a series, keep the other balls one by one, on the other plate. There are 2 possible outcomes. 1) out of the 11 balls, 10 are identical in weight with the 1st ball. Find out which is different and if it's heavier or lighter. 2) the ball you took is the different one. In this case, check whether the other balls are different in weight compared to this one, and note down. Is it right? Or am I missing something? context |
