Why this answer is correct
The logic follows here,
Hence, the correct answer is "Option 3".
In a certain code language,
A ! B means ‘A is the wife of B’,
A > B means ‘A is the sister of B’,
A = B means ‘A is the father of B’ and
A − B means ‘A is the son of B’.
How is N related to E if ‘N > U − R ! S = E’?
Sister's daughter
Daughter's sister
Sister
Daughter
Correct answer
Sister
Why this answer is correct
Family Chart:
Let us first decode the given symbols and then draw a family tree.
| Symbol | ! | > | = | - |
|---|---|---|---|---|
| Meaning | Wife | Sister | Father | Son |
Given : N > U − R ! S = E
From the family tree, it is clear that R and S are parents of N, U, and E. Since N is female, she is the sister of both U and E.
Hence, the correct answer is 'Option 3'.

Hence, the correct answer is "option 4"
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 etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(13, 33, 5)
(6, 40, 19)
(20, 37, 12)
(8, 46, 22)
(9, 39, 15)
(17, 33, 10)
Correct answer
(9, 39, 15)
Why this answer is correct
The logic followed here is:
Logic: Second Number = First Number + Third Number + 15
For the first set (13, 33, 5)
⇒ 13 + 5 + 15
⇒ 18 + 15 = 33.
For the second set (6, 40, 19)
⇒ 6 + 19 + 15
⇒ 25 + 15 = 40.
Applying the same logic to the correct set (9, 39, 15)
⇒ 9 + 15 + 15
⇒ 24 + 15 = 39.
Hence, the correct answer is 'Option 3'.

Why this answer is correct
Family Chart:
The family tree diagram,
From the family tree, it is evident that G is the sister of J, and J is the wife of M. Therefore, G is the Wife's sister of M.
Hence, the correct answer is 'Option 4'.
Based on the English alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that does not belong to that group?
(Note: The odd man out is not based on the number of consonants/vowels or their position in the letter cluster.)
GFI
BAD
NMP
VUY
Correct answer
VUY
Why this answer is correct
The logic follows here,
Logic: Second letter = First letter − 1; Third letter = Second letter + 3.
For GFI,
For BAD,
For NMP,
For VUY,
This letter cluster does not follow the rule.
Therefore, the letter cluster that is different from the others is VUY.
Hence, the correct answer is 'Option 4'.
LPBF is related to QUGK in a certain way based on the English alphabetical order. In the same way, FJVZ is related to KOAE. To which of the following options is UYKO related, following the same logic?
ZOPT
ZDTP
ZDPT
ZTPO
Correct answer
ZDPT
Why this answer is correct
The logic followed in this pattern is a constant shift in the English alphabetical order.
For 'LPBF' related to 'QUGK':
| L(12) | P(16) | B(2) | F(6) |
|---|---|---|---|
| +5 ↓ | +5 ↓ | +5 ↓ | +5 ↓ |
| Q(17) | U(21) | G(7) | K(11) |

|---|---|---|---|
| +5 ↓ | +5 ↓ | +5 ↓ | +5 ↓ |
| K(11) | O(15) | A(1) | E(5) |
Applying the same logic to 'UYKO':
| U(21) | Y(25) | K(11) | O(15) |
|---|---|---|---|
| +5 ↓ | +5 ↓ | +5 ↓ | +5 ↓ |
| Z(26) | D(4) | P(16) | T(20) |
Thus, UYKO is related to ZDPT.
Hence, the correct answer is 'Option 3'.

If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will come in place of the question mark ‘?’ in the following equation?
10 A 2 C 35 B 2 = ? C 20
45
50
35
55
Correct answer
55
Why this answer is correct
BODMAS rule:
Operator conversion:
| A | B | C | D |
|---|---|---|---|
| ÷ | × | + | − |
After replacing and using BODMAS rule:
⟹ 10 ÷ 2 + 35 × 2 = ? + 20
⟹ 5 + 35 × 2 = ? + 20
⟹ 5 + 70 = ? + 20
⟹ 75 = ? + 20
? = 55
The value of the question mark is 55.
Hence, the correct answer is "option 4"

Read the given statement(s) 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 statement(s).
Statements:
Some pickles are seeds.
All seeds are flowers.
Conclusions:
(I) Some pickles are flowers.
(II) All flowers are seeds.
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
The least possible Venn diagram for the given statements is:
Conclusions:
(I) Some pickles are flowers. **- Follow (**Some pickles are seeds. All seeds are flowers. Hence, Some pickles are flowers is true)
(II) All flowers are seeds - Does not follow (Some pickles are seeds. All seeds are flowers.All flowers are seeds is may be possible but not definite Hence, it is false)
Only conclusion (I) follows
Hence, the correct answer is “Option 2”.
If 2 is added to each odd digit and 1 is subtracted from each even digit in the number 1528634, then what will be the sum of the digits that are second from the left and second from the right in the new number thus formed?
14
13
12
10
Correct answer
12
Why this answer is correct
Given number: 1528634
According to information if 2 is added to each odd digit and 1 is subtracted from each even digit in the number ,
Left 3 7 1 7 5 5 3 Right
So, the sum of the digit second from the left and the digit second from the right is:7 + 5 = 12.
Hence, the correct answer is 'Option 3'.

LO –NK –JM
CB - AD - EF
OR - QN - RV
PS - TW - VR
KN - MJ - IL
Correct answer
KN - MJ - IL
Why this answer is correct
The logic follows here,
For FI − HE − DG:
For LO − NK − JM:
Applying the same logic,

Hence, the correct answer is "Option 4".
Read the given statement(s) 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 statement(s).
Statements:
All hens are shirts.
All cats are shirts.
Conclusions:
(I) Some hens are cats.
(II) Some shirts are cats.
Neither conclusion (I) nor (II) follows
Only conclusion (I) follows
Both conclusions (I) and (II) follow
Only conclusion (II) follows
Correct answer
Only conclusion (II) follows
Why this answer is correct
The least possible Venn diagram for the given statements is:
Conclusions:
(I) Some hens are cats - Does not follow
(As there is no direct relation between the hens and the cats may be it is possible but not definite. Hence, it is false)
(II) Some shirts are cats. - Follow (All cats are shirts and some cats are shirts and some shirts are cats is true)
Therefore, only conclusion (II) follows.
Hence, the correct answer is “Option 4”.
Based on the alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that 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.)
CAD
IGK
FDG
KIL
Correct answer
IGK
Why this answer is correct
The logic followed here is,
Logic: First letter − 2 = Second letter; Second letter + 3 = Third letter.
For CAD,
For FDG,
For KIL,
For IGK
Therefore, the letter cluster that is different from the others is IGK.
Hence, the correct answer is 'Option 2'.
Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the one that does not belong to that group?

SU-KE
DF-WP
HJ-ZT
UW-MG
Correct answer
DF-WP
Why this answer is correct
The logic follows here,
For SU-KE,
For DF-WP,
For HJ-ZT,

Hence, the correct answer is 'Option 2'.
In a row of 214 students facing north, Rt is 164th from the left end. If Kl is 37th to the right of Rt, what is Kl's position from the right end of the line?
12th
13th
14th
11th
Correct answer
14th
Why this answer is correct
The logic followed here is:
Total number of students in the line = 214
Position of Rt from the left end = 164th
Position of Kl from the left end = Position of Rt from the left end + 37
= 164 + 37
= 201st
Position of Kl from the right end = (Total number of students + 1) − Position of Kl from the left end
= (214 + 1) − 201
= 215 − 201
= 14th
So, Kl is 14th from the right end of the line.
Hence, the correct answer is "Option 3"

164
178
176
160
Correct answer
176
Why this answer is correct
The logic follows here,
Logic: Each number in the given series is obtained by dividing the preceding number by 2.
Hence, the correct answer is "option 3"

4
0
7
3
Correct answer
