 Brain Teaser: you have 7 seemingly identical looking balls, only 1 is slightly lighter than the other 6. You are given a scale. How can you find the 1 lighter ball is you are only allowed to use the scale twice.4 Answerspick 3 random balls on one side of the scale, pick 3 more to put on the other end. if scale equals, the 1 unpicked ball is the lighter one. if one side is lighter than the other one, the lighter ball is among them. take 1 random ball out of 3 to put on one side the scale, put another on the other side...you get it by now.can we not pick 2 on each side?You can start with 2 or 3 on each side and still only measure twice...doesn't matter. Second step would be to measure 2 of the 3 balls from the lighter side. Regardless, it's a dumb question to ask someone on an interview.Show More ResponsesAdd one ball to the scale at a time continuously . The lighter ball will show a slight difference at the scale when you adding up the weight. Like if the first ball is 12g, then adding the next one will be 24, 36, etc and the one that was slightly off will be the lighter one. I think this count as using the scale once because I use it continuously

 You are in a boat which is in the middle of a pond and you are holding a rock in your hand. You throw the rock into the lake. Does the water level of the lake rise?6 AnswersNo right or wrong answer. They just want to see how you think.The water level will drop. When you hold the rock, the extra displaced volume of water equals the weight of the rock. When you throw the rock into the lake, displaced volume is the size of the rock, which is less.both wrong. the water level does not change. at first the density the boat has is density of the boat + density of rock affecting water level. in the final situation the boat has gotten rid of the rock's density, but the rock (and its density) have been added to the lake, so we still have density of boat + density of rock affecting water level. location doesn't change physics.Show More ResponsesThe water level decreases when the rock leaves your hand, then increases again when the rock enters the water.Does the final answer depend on the rock's density compared to the density of water?While the rock is in the boat the displaced water has the same weight as the rock when the rock is in the water the volume of water displaced is the same as the volume of the rock. So the level of the water rises or falls depending on the density of the rock
