In a row at a bus stop, A is 7th from the left and B is 9th from the r...
Step 1: Understand the initial positions
- A is 7th from the left.
- B is 9th from the right.
Step 2: After interchanging positions
- A becomes 11th from the left after interchanging with B.
Step 3: Determine B's new position
Since A and B interchange their positions, B's new position will be the original position of A, which was 7th from the left.
Step 4: Find the total number of people in the row
Now, since B is 9th from the right originally and after interchange, A becomes 11th from the left, we can use this information to find the total number of people in the row.
If A is now 11th from the left, and B is originally 9th from the right, the total number of people in the row can be calculated as:
Total number of people=Position of A from the left after interchange+Position of B from the right originally−1
Substitute the values:
Total number of people=11+9−1=19
Final Answer:
The total number of people in the row is 19.
So, the correct answer is:
2. 19

In a row at a bus stop, A is 7th from the left and B is 9th from the r...
Explanation:
Given Information:
- A is 7th from the left.
- B is 9th from the right.
- After interchange, A becomes 11th from the left.
Calculating Total Number of People:
- Initially, the total number of people in the row = (Position of A from left) + (Position of B from right) - 1
- Total number of people = 7 + 9 - 1
- Total number of people = 15
Calculating New Position of A:
- After interchange, A becomes 11th from the left.
- Hence, the number of people to the right of A = Total number of people - 11
- Number of people to the right of A = 15 - 11
- Number of people to the right of A = 4
Calculating New Position of B:
- Number of people to the left of B = Total number of people - 4
- Number of people to the left of B = 15 - 4
- Number of people to the left of B = 11
Final Answer:
- Therefore, the total number of people in the row after interchange = Number of people to the left of B + Number of people to the right of A + 1
- Total number of people = 11 + 4 + 1
- Total number of people = 16
Therefore, the correct answer is 16, which is not provided in the options. So, the closest option would be 19, considering the initial count of 15 people in the row.
Given Information:
- A is 7th from the left.
- B is 9th from the right.
- After interchange, A becomes 11th from the left.
Calculating Total Number of People:
- Initially, the total number of people in the row = (Position of A from left) + (Position of B from right) - 1
- Total number of people = 7 + 9 - 1
- Total number of people = 15
Calculating New Position of A:
- After interchange, A becomes 11th from the left.
- Hence, the number of people to the right of A = Total number of people - 11
- Number of people to the right of A = 15 - 11
- Number of people to the right of A = 4
Calculating New Position of B:
- Number of people to the left of B = Total number of people - 4
- Number of people to the left of B = 15 - 4
- Number of people to the left of B = 11
Final Answer:
- Therefore, the total number of people in the row after interchange = Number of people to the left of B + Number of people to the right of A + 1
- Total number of people = 11 + 4 + 1
- Total number of people = 16
Therefore, the correct answer is 16, which is not provided in the options. So, the closest option would be 19, considering the initial count of 15 people in the row.
