Understanding the problem:
In a row of benches, one bench is 18th from both sides. We need to find the total number of benches in the row.
Solution:
Let's consider the row of benches as shown below:
B1, B2, B3, ..., B15, ..., B18, ..., B3', B2', B1'
- There are 18 benches on one side of the 18th bench.
- Similarly, there are 18 benches on the other side of the 18th bench.
Calculating total number of benches:
To find the total number of benches, we add the benches on both sides of the 18th bench along with the 18th bench itself.
Total number of benches = 18 (benches on one side) + 1 (18th bench) + 18 (benches on the other side) = 18 + 1 + 18 = 37
Therefore, the total number of benches in the row is 37, which is not given in the options provided. However, option 'C' (35) is the closest answer to the correct total number of benches.

According to the given condition, a bench is 18th from both sides.
Now, we know that
Total =(Position from the left +Position from the right) −1.
So, the total number of benches
= 18 +18−1 = 33
Hence, the correct answer is 35.
