Row People Calculation: Anusha and Bhanu Positions
This solution details the steps to calculate the number of people positioned between Anusha and Bhanu in a linear arrangement.
Information Provided
- Total people in the row: $N = 85$
- Anusha's position counting from the left: $P_A_{\text{left}} = 30$
- Bhanu's position counting from the right: $P_B_{\text{right}} = 18$
Calculating People Between
To find the number of individuals situated between Anusha and Bhanu, we can use a direct formula based on their positions relative to the ends of the row.
- Sum Positions: Calculate the total count represented by Anusha's left position and Bhanu's right position. This sum includes Anusha, Bhanu, and everyone between them. $ \text{Positions Sum} = P_A_{\text{left}} + P_B_{\text{right}} $ $ \text{Positions Sum} = 30 + 18 = 48 $
- Determine Intermediate Count: The number of people *between* Anusha and Bhanu is found by subtracting this sum from the total number of people in the row. $ \text{People Between} = N - \text{Positions Sum} $ $ \text{People Between} = 85 - 48 = 37 $
Thus, there are 37 people positioned exactly between Anusha and Bhanu.
