Number, Ranking and Time Sequence Test

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 chapter, 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.

Type of Questions

Generally three types of questions based on number, ranking and time sequence test are asked in various competitive exams.

Type #1:

Number Test

In this type of questions, a number/a set of In this type of questions, a number/a set of numbers/a series of digits is given and the candidates are asked to find out digits following certain given conditions.

Example:  How many 5's are there in the following sequence which are preceded by 3 but not followed by 8?

4 5 8 3 2 7 3 5 1 7 8 9 3 5 8 3 1 3 5 2

(a) 4 (b) 3 (c) 2 (d) 1

Solutions (c) 4 5 8 3 2 7 3 5 1 7 8 9 3 5 8 3 1 3 5 2So, it is clear from above that three are two 5's in the given sequence which are preceded by 3 but not followed by 8.

Type #2:

Ranking Test

In this type of questions, generally, the rank of a person either from the top/bottom or from right/left or the total number of persons is to be find out based on conditions given in question.

The position or rank can be calculated with the help of following formulae

1. 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]

2. 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

3. 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

4. In case of interchanging of positions

(a) Total number of persons =

[Initial position of 1st person + Interchanged position of 2nd person] - 1

(b) New position of 2nd person =

[Difference in the two positions of 1st person] + [Initial position of 2nd person]Type #3:

Time Sequence Test

In this type of questions, candidates are required to find out a particular day or time based on some given conditions.

To solve such type of problems, the candidate must have a basic knowledge regarding calendar and clock.

Example: Sunita leaves her house at 20 min to seven in the morning, reaches Vineeta's house in 25 min, they finish their breakfast in another 15 min and leave for their office which takes another 35 min. At what time, did they leave Vineeta's house to reach their office?

(a) 7 : 40 am (b) 7 : 20 am

(c) 7 : 45 am (d) 8 : 15 am

Solutions (b) Sunita leaves her house at 6 : 40 am.

She reaches Vineeta's house in 25 min,

i.e. 6 : 40 + 0 : 25 at 7 : 05 am.

Both leave for office, 15 min after 7 : 05 am

i.e. 7 : 05 + 0 : 15 at 7 : 20 am.
