In a row of trees, a tree is at 11th place in the row from the left and 16th place from the right. How many trees are there in this row ?

Question

Accepted Answer

To determine the total number of trees in the row, we need to consider the positions of the tree from both the left and the right sides. The tree is at the 11th position from the left and the 16th position from the right.

To find the total number of trees, we can use the formula:

$$ \text{Total number of trees} = (\text{Position from the left}) + (\text{Position from the right}) - 1 $$

Substituting the given values:

$$ \text{Total number of trees} = 11 + 16 - 1 = 26 $$

Therefore, the total number of trees in the row is 26, which corresponds to Option 2.

**Explanation for why each option is incorrect:**

1. **Option 1 (25):** If there were 25 trees, then the calculation would be $11 + 16 - 1 = 26$, which does not match 25. Therefore, Option 1 is incorrect.

2. **Option 3 (27):** If there were 27 trees, then the calculation would be $11 + 16 - 1 = 26$, which does not match 27. Therefore, Option 3 is incorrect.

3. **Option 4 (28):** If there were 28 trees, then the calculation would be $11 + 16 - 1 = 26$, which does not match 28. Therefore, Option 4 is incorrect.

In conclusion, the correct answer is Option 2, as the calculation accurately reflects the total number of trees in the row.
