Q. No. 57:
In a row at a bus stop, A is 9th from the right and B is 7th from the left. They both interchange their positions. If there are 20 people in the row, what will be the new position of B from the left ?
Answer: B Number of people in the row = Position of person from left + Position of person from right - 1. A is 9th from the right. Also, there are 20 people in the row. Thus, 20 = Position of A from left + 9-1 Position of A from left = 12. When, A and B interchange positions. As old position become Bs new position. Thus, B is now 12th from left.
