Can anyone give me the quickest idea to solve the question below?
Read the information below and answer the question that follows.
In a mathematical game, one hundred people are standing in a line and they are required to count off in fives as "one, two, three, four five, one, two, three, four, five," and so on from the first person in the line. The person who says "five" is taken out of the line. Those remaining repeat this procedure until only four people remain in the line.
What was the original position in the line of the last person to leave?
A. 93 B. 96 C. 97 D. 98
If any one can elaborate with more similar kind of example then it will be very nice.
