A farmer wanted to sell watermelons in the city. To reach the city, he had to cross a river. So, he embarked on the journey while it was raining. On the way, he felt hungry and thus ate one of the watermelons. Further on a certain distance, he came across a Shark. In order to save himself, he hit the shark with the watermelon.
At this point of time, can you find out if there is any change in the water level?
