Each of the digits in the number 8123457 is arranged in ascending order from left to right. The position(s) of how many digits will remain unchanged as compared to that in the original number?
Three
Two
One
None
Correct answer
None
Why this answer is correct
Given:
The original number is 8123457.
The digits, when arranged in ascending order from left to right, form the number: 1234578.
| Position | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th |
|---|---|---|---|---|---|---|---|
| Original Digit | 8 | 1 | 2 | 3 | 4 | 5 | 7 |
| Arranged Digit | 1 | 2 | 3 | 4 | 5 | 7 | 8 |
Thus, the position of zero digits remains unchanged.

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group?
(
Note:
The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
DGF
ORQ
POT
FIH
Correct answer
POT
Why this answer is correct
The letter-cluster that DOES NOT belong to the group is POT.
The logic followed here is:
Option 1) 'DGF':
Pattern: (+3, -1).
Option 2) 'ORQ':
Pattern: (+3, -1).
Option 3) POT
Pattern: (-1, +5). (does not follow same pattern)
Option 4) 'FIH':
Pattern: (+3, -1).
Thus, the letter-cluster that DOES NOT belong to that group is POT.
Hence, the correct answer is "Option 3".

Select the pair which follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern.
JLO−QSV
TVY−ACF
NOQ−TVY
NPS−UWZ
NPS−TWY
NOQ−UWZ

NIRR
MJQR
Correct answer
NIRR
Why this answer is correct
Logic followed here is.
Logic: The letters of the first word are shifted backwards by decreasing values (-5, -4, -3, -2) based on their positional values in the English alphabet to obtain the corresponding letters of the related word.
For
MHSD is related to HDPB →
LNPB is related to GJMZ →
The pattern observed is: The letters are shifted by -5, -4, -3, and -2 respectively.
Similarly, let's find the related word for SMUT:
Therefore, the word related to 'SMUT' is 'NIRR'.
Hence, the correct answer is "Option 3".
In a row of 58 people facing the north, Jolly sits 19th from the left end. If Bela sits 17th to the right of Jolly, then what is Bela’s position from the right end of the line?
23rd
24th
20th
22nd
Correct answer
23rd
Why this answer is correct
Given:
→ Total people = 58
→ Jolly sits 19th from the left end
→ Bela sits 17th to the right of Jolly
Step 1: Find Bela's position from the left
Bela's position from left = 19 + 17 = 36
Step 2: Find Bela's position from the right
Position from right = Total people − Position from left + 1
= 58 − 36 + 1
= 23
Therefore, Bela is 23rd from the right end.
Hence, the correct answer is Option 1.

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements: Some seats are plates.
All plates are chairs.
Conclusion (I): Some seats are chairs.
Conclusion (II): All chairs are plates.
Neither conclusion (I) nor (II) follows.
Only conclusion (I) follows.
Only conclusion (II) follows.
Both conclusions (I) and (II) follow.
Correct answer
Only conclusion (I) follows.
Why this answer is correct
**Given
Statements:
**
Some seats are plates.
All plates are chairs.
Conclusions:
(I) Some seats are chairs: Follows (because some seats are plates and all plates are chairs.)
(II) All chairs are plates: Does not follows (because only plates are chairs is given, not all chairs are plates.
Therefore, only conclusion (I) follows.
Hence, the correct answer is Option 2.
Refer to the given series and answer the question that follows.
All numbers are single-digit numbers only. Counting to be done from left to right.
(Left) 5 2 8 1 6 3 7 9 4 2 8 7 1 9 6 4 3 5 9 8 2 1 1 7 6 3 (Right).
How many such even digits are there, each of which is immediately preceded by an even digit and also immediately followed by an odd digit?
Five
Four
Three
Two
Correct answer
Four
Why this answer is correct
Given Series:
(Left) 5 2 8 1 6 3 7 9 4 2 8 7 1 9 6 4 3 5 9 8 2 1 1 7 6 3 (Right)
Required pattern:
Even → Even → Odd
Checking the series:
(Left) 5 2 8 1 6 3 7 9 4 2 8 7 1 9 6 4 3 5 9 8 2 1 1 7 6 3 (Right)
Even digits satisfying the condition:
→ 8 in (2 8 1)
→ 4 in (6 4 3)
→ 2 in (8 2 1)
→ 8 in (2 8 7)
Therefore, there are 4 such even digits.
Hence, the correct answer is "Option 2".
Mohak starts from Point A and drives 12 km towards the south. He then takes a left turn, drives 11 km, turns left and drives 15 km. He then takes a left turn and drives 14 km. He takes a final left turn, drives 3 km and stops at Point P. How far (shortest distance) and towards which direction should he drive in order to reach Point A again? (All turns are 90-degree turns only unless specified.)
4 km to the west
4 km to the east
3 km to the east
3 km to the west
Correct answer
3 km to the east
Why this answer is correct
Given:
→ Mohak starts from Point A
→ 12 km south
→ Left turn, 11 km
→ Left turn, 15 km
→ Left turn, 14 km
→ Left turn, 3 km to Point P
Vertical movement:
→ South = 12 + 3 = 15 km
→ North = 15 km
Vertical position becomes 0.
Horizontal movement:
→ East = 11 km
→ West = 14 km
Net movement = 3 km west.
So, Point P is 3 km west of Point A.
To reach Point A again, Mohak should travel 3 km towards the east.
Hence, the correct answer is Option 3.
In a certain code language GYSU is coded as 74 and MAKZ is coded as 53. What is the code for IHOW in that language?
57
51
59
60
Correct answer
57
Why this answer is correct
Logic followed here is: The code for a word is determined by summing the positional values of its letters and then adding a (+2) to the sum.
For
GYSU is coded as 74 →
Sum of positional values = 7 + 25 + 19 + 21 = 72
Code = 72 + 2 = 74
MAKZ is coded as 53 →
Sum of positional values = 13 + 1 + 11 + 26 = 51
Code = 51 + 2 = 53
Similarly, let's find the code for IHOW:
Sum of positional values = 9 + 8 + 15 + 23 = 55
Code = 55 + 2 = 57
Therefore, the code for 'IHOW' is 57.
Hence, the correct answer is "Option 1".
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/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(14, 3, 42)
(12, 2, 24)
(5, 8, 36)
(13, 3, 39)
(18, 2, 9)
(15, 45, 3)
Correct answer
(13, 3, 39)
Why this answer is correct
Logic followed here is:
3rd number = 1st number × 2nd number
Set 1: (14, 3, 42): 14 × 3 = 42
Set 2: (12, 2, 24): 12 × 2 = 24
Similarly, option (2) (13, 3, 39): 13 × 3 = 39
Therefore, the related set is (13, 3, 39).
Hence, the correct answer is "Option 2".
