Number, Ranking and Time Sequence Test Questions and Answers

Q: How many persons are taller than Pavan ?

Four persons are taller than Pavan.Kiran is 2nd and Tarun 3rd. The first ranker is the shortest and is not Charan; Sravan is taller than one person, so he is not the shortest either. The first ranker is therefore Pavan, the shortest, and Sravan is the second shortest.Charan and Sravan take ranks 4 and 5. The fourth ranker is the tallest, and Sravan is second shortest, so Charan is 4th and tallest, and Sravan 5th. Tarun is taller than Kiran, which fixes the middle heights.RankPersonHeight order1Pavanshortest2Kiran3rd shortest3Tarun4th shortest4Charantallest5Sravan2nd shortestPavan is the first ranker, and the first ranker is the shortest of the five, so all the other four (Sravan, Kiran, Tarun and Charan) are taller than him. One, Two and Three would leave someone shorter than Pavan, which the clues rule out.

Q: 'A' is older than 'B' but younger than 'C'. 'D' is younger than 'E' but older than 'A'. If 'C' is younger than 'D', who is the oldest of all ?

The oldest of all is E.Write each statement as an inequality, with > meaning 'older than':A is older than B but younger than C: C > A > B.D is younger than E but older than A: E > D > A.C is younger than D: D > C.Combining them gives the full order E > D > C > A > B, so E is the oldest and B the youngest.D is only the second oldest, because the second statement places E above D. A sits in the middle and B at the bottom, so neither can be the oldest.

Q: In a row of boys, Srinath is 7th from the left and Venut is 12th from the right. If they interchange their positions, Srinath becomes 22nd from the left. How many boys are there in the row ?

There are 33 boys in the row.After they interchange, Srinath stands where Venut stood, and that place is 22nd from the left. Venut's old place was also 12th from the right. So one position is 22nd from the left and 12th from the right:\[ 22 + 12 - 1 = 33 \]The 1 is subtracted because that boy's place is counted from both ends. Srinath's original place, 7th from the left, is not needed for the count. Adding 22 and 12 without subtracting gives 34, which is not an option; 43, 37 and 51 match no correct working.

Q: In a class of boys stands in a single line. One boy is nineteenth in order from both ends. How many boys are there in the class ?

There are 37 boys in the class.The boy is 19th from each end, so there are 18 boys on each side of him:\[ 18 + 1 + 18 = 37 \]Equivalently, total = position from left + position from right \(-\) 1 \(= 19 + 19 - 1 = 37\). 38 would count the boy twice and is not offered; 27, 39 and 47 do not fit the symmetric position at all, since the total must be odd with him in the exact middle.

Q: Consider that(a) A is taller than B(b) C is taller than A(c) D is taller than C(d) E is the tallest of allIf they are made to sit in the above order of their height, who will occupy the mid position ?

C occupies the middle position.Put the four conditions together, from tallest to shortest:E is the tallest of all.D is taller than C, and C is taller than A.A is taller than B.So the order is E, D, C, A, B. With five people the middle seat is the third, and the third person in either direction is C.A and B are the two shortest, at positions four and five, and D is second, so none of them sits in the middle.

Q: Nita is the 11th from the either end of the row of girls, how many girls are there in the row ?

There are 21 girls in the row.If Nita is 11th from the left, 10 girls stand to her left; if she is also 11th from the right, 10 girls stand to her right. Counting her once:\[ \begin{aligned} \text{total} &= 10 + 1 + 10 \\ &= 11 + 11 - 1 = 21 \end{aligned} \]The general rule is: position from left + position from right − 1. Answering 22 counts Nita twice, and 20 or 19 leave out girls.

Q: Ram walks slower than Raju and Raju walks as fast as Gora and Kabi walks faster than Gora. Who walks the fastest ?

The fastest walker is Kabi.Put the statements in order of speed:Ram is slower than Raju, so Raju > Ram.Raju walks as fast as Gora, so Raju = Gora.Kabi walks faster than Gora, so Kabi > Gora.Combining them: Kabi > Gora = Raju > Ram. Kabi is ahead of everyone. Raju and Gora tie for second place, and Ram is the slowest.Writing the comparisons as an inequality chain, as above, is the safe method for any such ordering question: it shows at once who is at each end.

Q: How many such digits are there in the number '46315825' each of which as far away, from the beginning of the numbers as when the digits are rearranged in ascending order ?

There are Two such digits.Write the number and its digits in ascending order, position by position:Number46315825Ascending12345568The digits that stay in the same position are 3 (third place) and 5 (fifth place). Every other position changes, so the count is two, not one, three or four.Remember that the repeated digit 5 appears twice in the sorted order, at the fifth and sixth places, so the comparison must be made position by position.

Q: 'H' is 16th from top and 12th from the bottom in merit in the class. How many students are there in the class ?

There are 27 students.H is counted once from each end, so there are 15 students above H and 11 below.\[ \text{total} = 16 + 12 - 1 = 27 \]28 counts H twice, the usual slip, and 29 adds one more again.The general rule: if a person is p-th from the top and q-th from the bottom, the total is p + q - 1.

Important Instructions

Direction for [ Question No: 41 To 41 ] :

Directions : These questions are based on the following information.

Pavan, Sravan, Charan, Tarun and Kiran are the top five rankers in a class, not necessarily in the same order. Each of these five is of a different height. The tallest person is the fourth ranker while Kiran is the second ranker. Tarun is taller than at least two persons and is the third ranker. The shortest person is the first ranker but he is not Charan. Sravan is taller than only one person and Tarun is taller than Kiran.

How many persons are taller than Pavan ?

A.One
B.Two
C.Three
D.Four

Exam Year(s)

Punjab Civil Service - 2021,

Answer: D

Four persons are taller than Pavan.

Kiran is 2nd and Tarun 3rd. The first ranker is the shortest and is not Charan; Sravan is taller than one person, so he is not the shortest either. The first ranker is therefore Pavan, the shortest, and Sravan is the second shortest.

Charan and Sravan take ranks 4 and 5. The fourth ranker is the tallest, and Sravan is second shortest, so Charan is 4th and tallest, and Sravan 5th. Tarun is taller than Kiran, which fixes the middle heights.

Rank	Person	Height order
1	Pavan	shortest
2	Kiran	3rd shortest
3	Tarun	4th shortest
4	Charan	tallest
5	Sravan	2nd shortest

Pavan is the first ranker, and the first ranker is the shortest of the five, so all the other four (Sravan, Kiran, Tarun and Charan) are taller than him. One, Two and Three would leave someone shorter than Pavan, which the clues rule out.

In a class of 35 students Kamal is placed seventh from the bottom whereas Suresh is placed ninth from the top. Ramesh is placed exactly in between the two. What is Kamal's position from Ramesh?

A.9
B.10
C.11
D.13

Exam Year(s)

TNPSC Group 1 - 2024, TNPSC - 2024,

Answer: C

In a class of 35, Kamal is 7th from the bottom, which is 29th from the top, and Suresh is 9th from the top. Ramesh stands exactly midway, at the 19th place from the top.

Counting the places from Ramesh to Kamal inclusively, Kamal is the 11th from Ramesh (19th to 29th), which is option C, the final key. The plain difference of 10, option B, was the booklet tick that the final key changed.

Counting the line from the top, Suresh is 9th, Kamal is 29th (35 - 7 + 1), and Ramesh is at the middle place 19. Counting inclusive from Ramesh to Kamal the position is 11th, which is the final key. The simple difference of 10 would be correct if the question asked how many places are between them plus one less.

'A' is older than 'B' but younger than 'C'. 'D' is younger than 'E' but older than 'A'. If 'C' is younger than 'D', who is the oldest of all ?

Exam Year(s)

Tripura Public Service Commission - 2015,

Answer: D

The oldest of all is E.

Write each statement as an inequality, with > meaning 'older than':

A is older than B but younger than C: C > A > B.
D is younger than E but older than A: E > D > A.
C is younger than D: D > C.

Combining them gives the full order E > D > C > A > B, so E is the oldest and B the youngest.

D is only the second oldest, because the second statement places E above D. A sits in the middle and B at the bottom, so neither can be the oldest.

In a row of boys, Srinath is 7th from the left and Venut is 12th from the right. If they interchange their positions, Srinath becomes 22nd from the left. How many boys are there in the row ?

A.33
B.43
C.37
D.51

Exam Year(s)

Tripura Public Service Commission - 2026,

Answer: A

There are 33 boys in the row.

After they interchange, Srinath stands where Venut stood, and that place is 22nd from the left. Venut's old place was also 12th from the right. So one position is 22nd from the left and 12th from the right:

\[ 22 + 12 - 1 = 33 \]

The 1 is subtracted because that boy's place is counted from both ends. Srinath's original place, 7th from the left, is not needed for the count. Adding 22 and 12 without subtracting gives 34, which is not an option; 43, 37 and 51 match no correct working.

In a class of boys stands in a single line. One boy is nineteenth in order from both ends. How many boys are there in the class ?

A.27
B.37
C.39
D.47

Exam Year(s)

Tripura Public Service Commission - 2026,

Answer: B

There are 37 boys in the class.

The boy is 19th from each end, so there are 18 boys on each side of him:

\[ 18 + 1 + 18 = 37 \]

Equivalently, total = position from left + position from right \(-\) 1 \(= 19 + 19 - 1 = 37\). 38 would count the boy twice and is not offered; 27, 39 and 47 do not fit the symmetric position at all, since the total must be odd with him in the exact middle.

Consider that

(a) A is taller than B
(b) C is taller than A
(c) D is taller than C
(d) E is the tallest of all

If they are made to sit in the above order of their height, who will occupy the mid position ?

Exam Year(s)

Tripura Public Service Commission - 2021,

Answer: C

C occupies the middle position.

Put the four conditions together, from tallest to shortest:

E is the tallest of all.
D is taller than C, and C is taller than A.
A is taller than B.

So the order is E, D, C, A, B. With five people the middle seat is the third, and the third person in either direction is C.

A and B are the two shortest, at positions four and five, and D is second, so none of them sits in the middle.

A.19
B.20
C.21
D.22

Exam Year(s)

Tripura Public Service Commission - 2021,

Answer: C

There are 21 girls in the row.

If Nita is 11th from the left, 10 girls stand to her left; if she is also 11th from the right, 10 girls stand to her right. Counting her once:

\[ \begin{aligned} \text{total} &= 10 + 1 + 10 \\ &= 11 + 11 - 1 = 21 \end{aligned} \]

The general rule is: position from left + position from right − 1. Answering 22 counts Nita twice, and 20 or 19 leave out girls.

Ram walks slower than Raju and Raju walks as fast as Gora and Kabi walks faster than Gora. Who walks the fastest ?

A.Raju
B.Ram
C.Gora
D.Kabi

Exam Year(s)

Tripura Public Service Commission - 2021,

Answer: D

The fastest walker is Kabi.

Put the statements in order of speed:

Ram is slower than Raju, so Raju > Ram.
Raju walks as fast as Gora, so Raju = Gora.
Kabi walks faster than Gora, so Kabi > Gora.

Combining them: Kabi > Gora = Raju > Ram. Kabi is ahead of everyone. Raju and Gora tie for second place, and Ram is the slowest.

How many such digits are there in the number '46315825' each of which as far away, from the beginning of the numbers as when the digits are rearranged in ascending order ?

A.One
B.Two
C.Three
D.Four

Exam Year(s)

Tripura Public Service Commission - 2025,

Answer: B

There are Two such digits.

Write the number and its digits in ascending order, position by position:

Number	4	6	3	1	5	8	2	5
Ascending	1	2	3	4	5	5	6	8

The digits that stay in the same position are 3 (third place) and 5 (fifth place). Every other position changes, so the count is two, not one, three or four.

Remember that the repeated digit 5 appears twice in the sorted order, at the fifth and sixth places, so the comparison must be made position by position.

'H' is 16th from top and 12th from the bottom in merit in the class. How many students are there in the class ?

A.29
B.27
C.28
D.None of these

Exam Year(s)

Tripura Public Service Commission - 2025,

Answer: B

There are 27 students.

H is counted once from each end, so there are 15 students above H and 11 below.

\[ \text{total} = 16 + 12 - 1 = 27 \]

28 counts H twice, the usual slip, and 29 adds one more again.

The general rule: if a person is p-th from the top and q-th from the bottom, the total is p + q - 1.
