Seven people, I, J, K, L, M, N and O, are sitting in a row, facing north.
Only three people sit between M and J. O sits to the immediate left of J. No one sits to the right of I. Only two people sit between I and O. N sits to the immediate right of L. How many people sit between K and N?
Four
Three
One
Two
Correct answer
Two
Why this answer is correct
Given: Seven people, I, J, K, L, M, N and O, are sitting in a row, facing north.
1) No one sits to the right of I.
2) Only two people sit between I and O.
3) O sits to the immediate left of J.
4) Only three people sit between M and J.
5) N sits to the immediate right of L.
After positioning all only one position is left which will be occupied by the only person left i.e. K.
Thus, two people sit between K and N.
Hence, "Option 4" is the correct answer.
Piyush ranked 35th from the top and 18th from the bottom in his class. How many students are there in his class?
53
52
54
51
Correct answer
52
Why this answer is correct
Given: Piyush ranked 35th from the top and 18th from the bottom in his class.
Piyush's Rank from Top = 35
Piyush's Rank from Bottom = 18
Total Students = (Piyush's Rank from Top) + (Piyush's Rank from Bottom) - 1
= 35 + 18 - 1 → 52
Hence, the correct answer is "Option 2".
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(
NOTE:
Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(112, 104, 96)
(136, 128, 120)
(129, 121, 116)
(91, 83, 77)
(140, 134, 130)
(154, 146, 138)
Correct answer
(154, 146, 138)
Why this answer is correct
The logic followed here is:
(112, 104, 96)
→ 112 - 8 = 104
→ 104 - 8 = 96
And,
(136, 128, 120)
→ 136 - 8 = 128
→ 128 - 8 = 120
Similarly,
(154, 146, 138)
→ 154 - 8 = 146
→ 146 - 8 = 138
Hence, "Option 4" is the correct answer.
Each of the digits in the number 81674293 is arranged in ascending order from left to right. Which of the following digits will be fourth from the left?
3
6
4
7
Correct answer
4
Why this answer is correct
Given: 81674293
According to the question.
| Given | 8 | 1 | 6 | 7 | 4 | 2 | 9 | 3 |
|---|---|---|---|---|---|---|---|---|
| Arranged in ascending order | 1 | 2 | 3 | 4 | 6 | 7 | 8 | 9 |
So, the digit that will be fourth from the left is → 4
Hence, "Option 3" is the correct answer.
Refer to the following number and symbol series and answer the question that follows.
All numbers are single-digit numbers. Counting to be done from left to right only.
(Left) 5 # % 2 ^ @ 3 & 1 $ 7 Ω 5 % # 6 * 1 9 (Right)
How many symbols in the series are immediately preceded by a symbol and immediately followed by a number$?
One
None
Two
Three
Correct answer
Three
Why this answer is correct
Given series: (Left) 5 # % 2 ^ @ 3 & 1 $ 7 Ω 5 % # 6 * 1 9 (Right)
According to the question:
Required condition: Symbol - Symbol - Number
(Left) 5 # % 2 ^ @ 3 & 1 $ 7 Ω 5 % # 6 * 1 9 (Right)
Thus, there are three such symbols which are immediately preceded by a symbol and immediately followed by a number.
Hence, "Option 4" is the correct answer.
Mr. Into ranked 96th from the top and 31st from the bottom in his class. How many students are there in his class?
126
128
123
125
Correct answer
126
Why this answer is correct
Given:
Mr. Into's rank from the top = 96
Mr. Into's rank from the bottom = 31
So, Total students = Rank from top + Rank from bottom - 1.
So, Total students = 96 + 31 - 1 = 126
Hence, the correct answer is "Option 1".

Correct answer
Daughter's husband's father
Why this answer is correct
Family Chart:
Given:
A is the father of H
H is the father of G
G is the son of E
F is the father of E
So, A is daughter's husband's father of F.
Hence, the correct answer is "Option 1".
A, B, C, D, E, F, and G are sitting around a circular table facing the centre.
Only two people sit between A and G when counted from the right of A. Only two people sit between G and C. Only three people sit between A and F. E sits to the immediate left of D.
How many people sit between C and E when counted from the right of C?
One
Three
Four
Two
Correct answer
One
Why this answer is correct
Given: A, B, C, D, E, F, and G are sitting around a circular table facing the center.
Only two people sit between A and G when counted from the right of A.
Only two people sit between G and C.
Only three people sit between A and F.
E sits to the immediate left of D.
After positioning all only one position is left which will be occupied by the only person left i.e. B.
Thus, one person sit between C and E when counted from the right of C.
Hence, the correct answer is "Option 1".
Town Q is to the east of Town P. Town R is to the south of Town Q. Town S is to the east of Town R. Town T is to the south of Town S. Town U is to the east of Town T. What is the position of Town U with respect to Town Q?
North-east
North-west
North
South-east
Correct answer
South-east
Why this answer is correct
Given:
Town Q is to the east of Town P.
Town R is to the south of Town Q.
Town S is to the east of Town R.
Town T is to the south of Town S.
Town U is to the east of Town T.
Q is at the top-left region.
U is diagonally down to the right of Q (toward the south-east).
So, Town U is to the South-East of Town Q.
Hence, the correct answer is "Option 4".

This question is based on the five, three-digit numbers given below.
(Left) 742 912 853 657 154 (Right)
(Example: 697 – First digit = 6, second digit = 9 and third digit = 7)
Note:
All operations to be done from left to right.
If all the numbers are arranged in descending order, the position(s) of how many numbers will remain unchanged?
Two
One
Three
Four
Correct answer
Two
Why this answer is correct
The logic followed here is:
Given numbers: 742, 912, 853, 657, 154
| Position | 1st | 2nd | 3rd | 4th | 5th |
|---|---|---|---|---|---|
| Numbers | 742 | 912 | 853 | 657 | 154 |
Arranging in descending order: 912, 853, 742, 657, 154
| Position | 1st | 2nd | 3rd | 4th | 5th |
|---|---|---|---|---|---|
| Numbers | 912 | 853 | 742 | 657 | 154 |
Here,
→ 657 remains in the 4th position
→ 154 remains in the 5th position
So, total numbers with unchanged positions = 2
Hence, the correct answer is Option 1.
Refer to the given number series and answer the question that follow (all numbers are single digit numbers only).

How many prime numbers are there in the number series?
Seven
Thirteen
Nine
Fourteen
Correct answer
Fourteen
Why this answer is correct
Given: (Left) 4 2 1 5 7 9 8 5 3 6 2 1 5 7 3 7 8 4 3 6 9 7 4 5 2 4 1 (Right)
Now,
We need to find the total count of prime numbers in the series.
Prime Numbers = 2, 3, 5, 7
(Left) 4 2 1 5 7 9 8 5 3 6 2 1 5 7 3 7 8 4 3 6 9 7 4 5 2 4 1 (Right)
| Prime Number | Occurrences |
|---|---|
| 2 | 3 |
| 3 | 3 |
| 5 | 4 |
| 7 | 4 |
Total prime numbers = 3 + 3 + 4 + 4 = 14
So, total prime numbers = 14
Hence, the correct answer is Option 4.

All 63 people are standing in a row, facing the north.
Mr. Zzz is \( 12^{th} \) from the left end while Mr. Ggg is \( 5^{th} \) from the right end.
How many people are there between Mr. Zzz and Mr. Ggg?
43
47
45
46
Correct answer
46
Why this answer is correct
Given: Mr. Zzz is 5th from the right in a row of 63 people. Mr. Ggg is 12th from the left.
Mr. Zzz’s position from right = 5
Mr. Ggg’s position from left = 12
Total number of people = 63
Number of people between = 63 − (12 + 5)
= 63 − 17
= 46
Hence, the correct answer is Option 4.
