Trees! How many trees? Mani and Kani are neighbours. They go to school together from their homes. One day on the way to school, Mani started counting the trees on his right side and said the total as 7. Kani also counted the trees on her left side and said the total as 5. When they reached the school, they told their friend Selvi about this.
