Que- A boat carrying steel balls is floating on the surface of water in a tank. If the balls are thrown into the tank one by one, how will it affect the level of water?

The boat with metal balls has more weight as compared to only metal balls, hence, initially due to weight of the boat+metal balls the level of water is more. but when the balls are thrown into tank the weight of boat decreases and so water lvl decreases. you must have heard the story of crow and the water pot, that he keeps on adding stones and water lvl increases but here it's totally opposite. I hope it helps you. :))
