In a row of students, if John, who is 16th from the left, and Johnson...
Given:
- John is 16th from the left.
- Johnson is 8th from the right.
- When John and Johnson interchange their positions, John becomes 33rd from the left.
To find:
The total number of students in the row.
Solution:
Let's assume the total number of students in the row is 'x'.
When John and Johnson interchange their positions, John becomes 33rd from the left. This means that there are 32 students to the left of John.
From the given information, we can deduce the following:
- Initially, there were 15 students to the left of John.
- After the interchange, there are 32 students to the left of John.
Therefore, the difference between the initial and final positions of John is 32 - 15 = 17.
This difference can be attributed to the students who were between John and Johnson initially. Since John was 16th from the left and Johnson was 8th from the right, the number of students between them would be (16 - 1) + (8 - 1) = 22.
Now, we can set up the equation to find the total number of students:
x = 15 + 17 + 22
x = 54
Hence, the total number of students in the row is 54.
Therefore, the correct option is C) 40.

When John and Johnson interchange their positions, John becomes 33rd from the left. This means that there are 32 students to the left of John.
From the given information, we can deduce the following:

Therefore, the difference between the initial and final positions of John is 32 - 15 = 17.
This difference can be attributed to the students who were between John and Johnson initially. Since John was 16th from the left and Johnson was 8th from the right, the number of students between them would be (16 - 1) + (8 - 1) = 22.
Now, we can set up the equation to find the total number of students:
x = 15 + 17 + 22
x = 54
Hence, the total number of students in the row is 54.
Therefore, the correct option is C) 40.
