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.

Selvi told the number of trees that had been counted by Mani and Kani is 12. Kani and Mani were surprised and asked "How did you say that?"

Selvi’s way of counting

Trees counted by Mani is 7     |  |  |  |  |  |  |  (Draw 7 lines)

Trees counted by Kani is 5     |  |  |  |  |  (Now draw 5 lines)

Total number of trees counted by both of them 12  

|  |  |  |  |  |  |  |  |  |
