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

Options

A. 25
B. 26
C. 27
D. 28

Explanation

To find the total number of trees in the row, we can use the following steps:

1. **Identify the positions**:
- The tree is at the 11th position from the left (denote this as L = 11).
- The tree is at the 16th position from the right (denote this as R = 16).

2. **Use the formula**:
The total number of trees (T) in the row can be calculated using the formula:
\[ T = L + R - 1 \]
where L is the position from the left and R is the position from the right.

3. **Substitute the values**:
Substitute the values of L and R into the formula:
\[ T = 11 + 16 - 1 \]

4. **Calculate the total**:
Perform the addition and subtraction:
\[ T = 27 - 1 = 26 \]

5. **Conclusion**:
Therefore, the total number of trees in the row is 26.
