Theory

• Number, ranking and time sequence test is based on arrangement of characters/ persons/ objects in a particular order based on some specific parameters.
• In this topic we deal with questions which have either a sequence of numbers, position of a person/object in a row/queue or time sequence test accompanied by some conditions.

Formula

• Total number of persons in a row = (Rank of a person from upper or left end) + (Rank of that person from lower or right end) -1 [because that particular place counts two times]
• Rank of a person from upper or left end = (Total number of persons in row) - (Rank of that person from lower or right end) + 1
• Rank of a person from lower or right end = (Total number of persons in row) - (Rank of that person from upper or left end) + 1
• In case of interchanging of positions
• Total number of persons = [Initial position of 1st person + Interchanged position of 2nd person] - 1
• New position of 2nd person = [Difference in the two positions of 1st person] + [Initial position of 2nd person]
