Question 1

In a row, A and B interchange positions. After interchange, A is 8th from left and B is 15th from left. If originally A was 3th from left, how many people are in the row?
Distance A moved = 5 positions. B moved same distance, so B's original position = 10. Total = B's original left position + (new_left_A - 1) = 20

Question 2

In a row, A and B interchange positions. After interchange, A is 14th from left and B is 24th from left. If originally A was 11th from left, how many people are in the row?
Distance A moved = 3 positions. B moved same distance, so B's original position = 21. Total = B's original left position + (new_left_A - 1) = 27

Question 3

In a row, A and B interchange positions. After interchange, A is 11th from left and B is 16th from left. If originally A was 3th from left, how many people are in the row?
Distance A moved = 8 positions. B moved same distance, so B's original position = 8. Total = B's original left position + (new_left_A - 1) = 24

Question 4

In a row, A and B interchange positions. After interchange, A is 14th from left and B is 20th from left. If originally A was 9th from left, how many people are in the row?
Distance A moved = 5 positions. B moved same distance, so B's original position = 15. Total = B's original left position + (new_left_A - 1) = 25

Question 5

In a row, A and B interchange positions. After interchange, A is 10th from left and B is 16th from left. If originally A was 4th from left, how many people are in the row?
Distance A moved = 6 positions. B moved same distance, so B's original position = 10. Total = B's original left position + (new_left_A - 1) = 22

Question 6

In a row, A and B interchange positions. After interchange, A is 8th from left and B is 16th from left. If originally A was 5th from left, how many people are in the row?
