Question 1

In a row, A and B interchange positions. After interchange, A is 11th from left and B is 17th from left. If originally A was 7th from left, how many people are in the row?
Distance A moved = 4 positions. B moved same distance, so B's original position = 13. Total = B's original left position + (new_left_A - 1) = 21

Question 2

In a row, A and B interchange positions. After interchange, A is 11th from left and B is 19th from left. If originally A was 4th from left, how many people are in the row?
Distance A moved = 7 positions. B moved same distance, so B's original position = 12. Total = B's original left position + (new_left_A - 1) = 26

Question 3

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 8th from left, how many people are in the row?
Distance A moved = 6 positions. B moved same distance, so B's original position = 14. Total = B's original left position + (new_left_A - 1) = 26

Question 4

In a row, A and B interchange positions. After interchange, A is 15th from left and B is 20th from left. If originally A was 4th from left, how many people are in the row?
Distance A moved = 11 positions. B moved same distance, so B's original position = 9. Total = B's original left position + (new_left_A - 1) = 31

Question 5

In a row, A and B interchange positions. After interchange, A is 9th from left and B is 19th from left. If originally A was 5th from left, how many people are in the row?
Distance A moved = 4 positions. B moved same distance, so B's original position = 15. Total = B's original left position + (new_left_A - 1) = 23

Question 6

In a row, A and B interchange positions. After interchange, A is 11th from left and B is 17th from left. If originally A was 4th from left, how many people are in the row?
