Number Ranking and Time Sequence Test Questions for Competitive Exams
Don't ignore number ranking and time sequence test topic questions because these topics are very important in competitive exams. So here in this blog, I am sharing with you number ranking and time sequence test questions with the definition, examples, and practice questions.
You can easily improve your performance with these selective questions and obtain a good rank in the competitive exams.
Number, Ranking and Time Sequence Test
Number Test:
In this type of question, generally, a set group or series of numerals is given and the candidate is asked to trace out numerals following certain given conditions or lying at specifically mentioned positions after shuffling according to a certain given pattern.
Ex.1. How many such 5s are there in the following number sequence each of which is immediately preceded by 3 or 4 but not immediately followed by 8 or 9?
3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0
(A) None
(B) Three
(C) Four
(D) Five
(E) None of these
Solution:
As you know, a number that comes after a given number is said to follow it while the one which comes before the given number precedes it.
Thus, the number satisfying the given conditions may be marked as follows:
3 5 9 5 4 
5 3 5 8 4 
6 7 3 
7 5 5 4 
2 3 
1 0
Clearly, there are five such 5s. Hence, the answer is (d).
Ranking Test:
In this type of questions, generally the ranks of a person both from the top and from the bottom are mentioned and the total number of persons is asked. However, sometimes this question is put in the form of a puzzle of interchanging seats by two persons.
Ex.1. Rohan ranks seventh from the top and twenty-sixth from the bottom in a class. How many students are there in the class?
(A) 31
(B) 32
(C) 33
(D) 34
Solution:
Clearly, the whole class consists of:
(i) 6 student who have ranks higher than Rohan;
(ii) Rohan; and
(iii) 25 students who have ranks lower than Rohan, i.e, (6+1+25) = 32 students. Hence, the answer is (b).
Time Sequence Test:
Ex.1. Satish remembers that his brother’s birthday is after fifteenth but before eighteenth of February whereas his sister Kajal remembers that her brother’s birthday is after sixteenth but below nineteenth of February. On which day in February is Satish’s brother’s birthday?
(A) 16th
(B) 17th
(C) 18th
(D) 19th
(E) None of these
Solution:
According to Satish, the brother’s birthday is on one of the days among 16th and 17th February.
According to Kajal, the brother’s birthday is on one of the days among 17th and 18th February.
Clearly, Satish’s brother’s birthday is on the day common to both the above groups, i.e., 17th February.
Practice Questions with Solutions:
Q.1. In these series given below, how many 8s are there each of which is exactly divisible by its immediately preceding as well as succeeding numbers?
2 8 3 8 2 4 8 2 4 8 6 8 2 8 2 4 8 3 8 2 8 6
(A) One
(B) Two
(C) Three
(D) Four
(E) None of these
Ans . B
Cleary we may mark such set of 3 numbers, in which the middle number is 8 and each of the two numbers on both sides of it is a factor of 8, as shown below:
2 8 3 8 2
4 8 6 8 
4 8 3 8 2 8 6 So, there are two such 8s. Hence, the answer is (b)
Q.2. The position of the first and the second digits in the numbers 94316875 are interchanged. Similarly, the positions of the third and fourth digits are interchanged and so on. Which of the following will be the third to the left of the seventh digit from the left end after the rearrangement?
(A) 1
(B) 4
(C) 6
(D) 8
(E) None of these
Ans . E
Changing the position of the digits as mentioned, we get the number: 49138657.
The seventh digit from the left end of this number is 5.
The third digit to the left of 5 is 3.
Hence, the answer is (e).
Q.3. If it is possible to form a number with the second, the fifth and the eight digits of the number 31549786, which is the perfect square of a two-digit even number, which of the following will be the second digit of that even number?
(A) 1
(B) 4
(C) 6
(D) No such number can be formed
(E) None of these.
Ans . B
The 2nd, 5th and 8th digits of the number 31549786 are 1, 9 and 6 respectively. The perfect square of a two-digit even number formed using the digits 1, 9 and 6 is 196. And, 196 = 142.
So, the required even number is 14. Clearly, its second digit is 4. Hence, the answer is (b).
Q.4. Manik is fourteenth from the right end in a row of 40 boys. What is his position from the left end?
(A) 24th
(B) 25th
(C) 26th
(D) 27th
(E) None of these
Ans . D
Clearly, number of boys towards the left of Manik = (40 – 14) = 26.
So, Manik is 27th from the left end.
Hence, the answer is (d).
Q.5. In a row of boys facing the North, A is sixteenth form the left end and C is sixteenth form the right end. B, who is fourth to the right of A, is fifth to the left of C in the row. How many boys are there in the row?
(A) 39
(B) 40
(C) 41
(D) 42
(E) None of these
Ans . B
Clearly, according to the given conditions, there are 15 boys to the left of A, as well as to the right of C. Also, B lies between A and C such that there are 3 boys between A and B; and 4 boys between B and C
So, number of boys in the row = ( 15+1+3+1+4+1+15)=40.
Hence, the answer is (b).
Q.6. In a row of girls, Kamya is fifth from the left and Preeti is sixth from the right When they exchange their position, then Kamya becomes thirteenth form the left. What will be Preeti’s position form the right?
(A) 7th
(B) 11th
(C) 14th
(D) 18th
Ans . C
Kamya’s new position is 13th from left. But it is the same as Preeti’s earlier position which is 6th from the right.
Thus, the row consists of ( 12 + 1 + 5) = 18 girls.
New, Preeti’s new position is Kamya’s earlier position which is 5th form the left. Number of girls to the right of Preeti = (18 – 5) = 13.
So, Preeti’s new position is 4th form the right.
Hence the answer is (C).
Q.7. Sam ranked ninth form the top and thirty-eighth form the bottom in a class. How many students are there in the class?
(A) 45
(B) 46
(C) 47
(D) 48
Ans . B
Clearly, number of students in the class = ( 8+1+37) = 46.

(A) 11 km
(B) 12 km
(C) 13 km
(D) 14 km
(E) 15 km
Ans . C
Clearly, according to sunita, the distance was more than 12 kms but less than 14 kms, which is 13 kms.
