A, B, C, D, E, F, G and H are sitting around a square table facing the centre of the table.
Some of them are sitting at the corners while some are sitting at the exact centre of the sides. A sits third to the right of C. H sits between B and G . F sits second to the right of C. D does not sit in a corner. G sits third to the right of D. Three people sit between D and C.
Who sits second to the left of B ?
E
D
A
H
Correct answer
A
Why this answer is correct
Given: A, B, C, D, E, F, G, and H are sitting around a square table facing the center of the table.
1) D does not sit in a corner.
2) G sits third to the right of D.
3) Three people sit between D and C.
4) F sits second to the right of C and A sits third to the right of C.
5) H sits between B and G.
So, E will sit in the remaining place.
Here, 'A' is second to the left of B.
Hence, the correct answer is "Option 3".
Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All black is white.
Some white is grey.
Conclusions:
I. Some grey is black.
II. Some white is black.
Only conclusion II follows
Neither conclusion I nor II follows
Both conclusions I and II follow
Only conclusion I follows
Correct answer
Only conclusion II follows
Why this answer is correct
Given
Statements:
All black is white.
Some white is grey.
The least possible Venn diagram for the given statement is:
Conclusions:
I. Some grey is black - False (Because, No definite relation given between grey and black, so it can be possible only).
II. Some white is black - True (Because, All black is white implies that some white is black).
So, Only conclusion II follows.
Hence, the correct answer is "Option 1".

So, D is the 'Son' of A.
Hence, the correct answer is "Option 4".
Select the option that is related to the third word in the same way as the second word is related to the first word.
Harrow : Gardener :: Scalpel : ?
Chef
Pilot
Surgeon
Teacher
Correct answer
Surgeon
Why this answer is correct
The logic followed here is:
Logic: The first word is the tool used by the professional (which is mentioned) in the second word.
Here,
Harrow : Gardener → Harrow is used by a Gardener.
Similarly,
Scalpel : Surgeon → Scalpel is used by a surgeon.
Hence, the correct answer is "Option 3".
Three statements are given followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All apples are pineapples.
Some apples are mangoes.
No mango is a grape.
Conclusions:
I. Some pineapples are not grapes.
II. No pineapple is a grape.
III. Some apples are not grapes.
Only conclusions I and III follow
Only conclusions I and II follow
All conclusions follow
Only conclusions II and III follow
Correct answer
Only conclusions I and III follow
Why this answer is correct
Given
Statements:
All apples are pineapples.
Some apples are mangoes.
No mango is a grape.
The least possible Venn diagram for the given statement is:
Conclusions:
I. Some pineapples are not grapes - True (All apples are pineapples, some apples are mangoes and no mango is a grape implies that some pineapples are not grapes)
II. No pineapple is a grape - False (Because, No definite relation is given between pineapple and grape, so it can be possible only)
III. Some apples are not grapes - True (Some apples are mangoes and no mango is a grape implies that some apples are not grapes)
So, Only conclusions I and III follow.
Hence, the correct answer is "Option 1".
Ten people are sitting in two parallel rows containing 5 people each, in such a way that there is equal distance between adjacent persons.
In Row 1 – A, B, C, D and E are seated and all of them are facing the south.

Which figure should replace the question mark (?) in the following series to continue the pattern?
Correct answer
Why this answer is correct
The logic followed here is:
Logic:
The arrow shows the shift in the pattern from 1 to 2:
The arrow shows the shift in pattern from diagrams 2 to 3 and C is changed to S
The arrow shows the shift in the pattern from 3 to 4:
The arrow shows the shift in pattern from diagrams 4 to 5 and
is changed to
as same shift that has been observed in step 2 to 3.
Hence, the correct answer is "Option 4".
If '+' means '÷', ‘-' means '+', '×' means ‘-', '÷' means '×', then what will come in place of the question mark (?) in the following equation?
49 - 6 ÷ 4 + 2 × 14 = ?
47
39
53
33
Correct answer
47
Why this answer is correct
Given Equation: 49 - 6 ÷ 4 + 2 × 14 = ?
BODMAS Rule:
Decoding the given information:
| Alphabet | + | - | × | ÷ |
|---|---|---|---|---|
| Meaning | ÷ | + | - | × |
Now replacing the sign from left to right using BODMAS Rule, we get:
49 + 6 × 4 ÷ 2 - 14
⇒ 49 + 6 × 2 - 14
⇒ 49 + 12 - 14
⇒ 61 - 14 = 47
Hence, the correct option is "Option 1".

If ‘* ( )’ stands for ‘bread butter cake’, ‘& ! ’ stands for ‘cake and cutter’, ‘) (!’ stands for ‘bread and butter’, then ‘ * *’ stands for:
Cutter Cutter Cutter
Butter Butter Butter
Bread Bread Bread
Cake Cake Cake
Correct answer
Cake Cake Cake
Why this answer is correct
The logic followed here is:
‘* ( )’ stands for ‘bread butter cake’
‘& ! *’ stands for ‘cake and cutter’
‘) (!’ stands for ‘bread and butter’
Here,
The ' * ' stands for cake.
Then, ‘ * ’ stands for 'Cake Cake Cake'.
Hence, the correct answer is "Option 4".
Select the option that is related to the sixth number in the same way as the first number is related to the second number and the third number is related to the fourth number.
399 : 7 :: 584 : 8 :: ? : 11
1221
1463
1583
110
Correct answer
1463
Why this answer is correct
The logic followed here is:
Logic: 2nd number × ((2nd number × (2nd number + 1)) + 1) = 1st number.
Now,
For, 399 : 7
⇒ 7 × ((7 × (7 + 1)) + 1)
⇒ 7 × ((7 × 8) + 1)
⇒ 7 × (56 + 1)
⇒ 7 × 57 = 399
For, 584 : 8
⇒ 8 × ((8 × (8 + 1)) + 1)
⇒ 8 × ((8 × 9) + 1)
⇒ 7 × (72 + 1)
⇒ 8 × 73 = 584
Similarly, for ? : 11
⇒ 11 × ((11 × (11 + 1)) + 1)
⇒ 11 × ((11 × 12) + 1)
⇒ 11 × (132 + 1)
⇒ 11 × 133 = 1463
Which two signs should be interchanged to make the given equation correct?
286 ÷ 13 × 2 + 50 - 6 = 0
÷ and ×
Correct answer
Why this answer is correct
Given equation: 286 ÷ 13 × 2 + 50 - 6 = 0
BODMAS Table:
Let's check each option one by one.
Option 1) + and ×
Given: 286 ÷ 13 × 2 + 50 - 6 = 0
After interchanging the signs we get:
⇒ 286 ÷ 13 + 2 × 50 - 6 = 0
⇒ 22 + 2 × 50 - 6 = 0
⇒ 22 + 100 - 6 = 0
⇒ 122 - 6
⇒ 116 ≠ 0
⇒ LHS ≠ RHS
Option 2) + and -
Given: 286 ÷ 13 × 2 + 50 - 6 = 0
After interchanging the signs we get:
⇒ 286 ÷ 13 × 2 - 50 + 6 = 0
⇒ 22 × 2 - 50 + 6 = 0
⇒ 44 - 50 + 6 = 0
⇒ 50 - 50 = 0
⇒ LHS = RHS
Option 3) ÷ and ×
Given: 286 ÷ 13 × 2 + 50 - 6 = 0
After interchanging the signs we get:
⇒ 286 × 13 ÷ 2 + 50 - 6 = 0
⇒ 286 × 6.5 + 50 - 6 = 0
⇒ 1859 + 50 - 6 = 0
⇒ 1909 - 6 = 0
⇒ 1903 ≠ 0
⇒ LHS ≠ RHS
Option 4) - and ×
Given: 286 ÷ 13 × 2 + 50 - 6 = 0
After interchanging the signs we get:
⇒ 286 ÷ 13 - 2 + 50 × 6 = 0
⇒ 22 - 2 + 50 × 6 = 0
⇒ 22 - 2 + 300 = 0
⇒ 322 - 2
⇒ 320 ≠ 0
⇒ LHS ≠ RHS
