45 ∶ 405 ∶ ∶ 20 ∶ 80 ∶ ∶ 85 ∶ ?
1270
1255
1445
1440
Correct answer
1445
Why this answer is correct
The logic followed here is:
Logic: (1st number)2 ÷ 5 = 2nd number.
Now,
For, 45 : 405
⇒ (45)2 ÷ 5 = 2025 ÷ 5 = 405.
For, 20 : 80
⇒ (20)2 ÷ 5 = 400 ÷ 5 = 80.
Similarly, for 85 ∶ ?
⇒ (85)2 ÷ 5 = 7225 ÷ 5 = 1445.
Hence, the correct answer is "Option 3".

Select the option that represents the letters that, when sequentially placed from left to right in the blanks below, will complete the letter series.
M N _ _ Q M _ O _ Q _ N _ P Q M N O _ _
PONPMOQP
OPNPMOPQ
OPPNMOQP
PONPOMPQ
Correct answer
OPNPMOPQ
Why this answer is correct
The logic followed here is:
Given Sequence: M N _ _ Q M _ O _ Q _ N _ P Q M N O _ _
Now, putting the letters in the blank spaces given in the option one by one:
Option 1) PONPMOQP → M N P O Q / M N O P Q / M N O P Q / M N O Q P
Option 2) OPNPMOPQ → M N O P Q / M N O P Q / M N O P Q / M N O P Q
Here, 'M N O P Q' is the pattern.
Option 3) OPPNMOQP → M N O P Q / M P O N Q / M N O P Q / M N O Q P
Option 4) PONPOMPQ→ M N P O Q / M N O P Q / O N M P Q / M N O P Q
Hence, the correct answer is "OPNPMOPQ".
Seven students, A, B, C, D, E, F and G, are standing in a straight line facing north. D is standing to the immediate left of E but to the immediate right of C. B is standing to the immediate right of A and to the immediate left of C. Similarly, F is standing to the immediate left of G, who is standing at the extreme right end. Who is standing at the third position from the left end?
B
E
D
C
Correct answer
C
Why this answer is correct
Given: Seven students, A, B, C, D, E, F and G, are standing in a straight line facing north.
1) B is standing to the immediate right of A and to the immediate left of C.
D is standing to the immediate left of E but to the immediate right of C.
Similarly, F is standing to the immediate left of G, who is standing at the extreme right end.
So, C is standing at the third position from the left end.
Hence, the correct answer is "C".

Observe the dots on a dice (one to six dots) in the following figures. How many dots are contained on the face opposite to that containing six dots?
One
Three
Five
Four
Correct answer
Three
Why this answer is correct
To find the opposite surface of 'six dots', we need to compare the common surface in the given dices,
So, From Dice 1 and Dice 2,
From both dices, one and two dots are common. So, remaining surface will be opposite to each other.
So, 'Three' dots will be the opposite face of 'Six dots'.
Hence, the correct answer is "Three"

Correct answer
2
Why this answer is correct
Given Equation: (8 B 4 A 3) D 7 = 33 D 11 A ?
BODMAS Rule:
Decoding the given information:
| Alphabet | A | B | C | D |
|---|---|---|---|---|
| Meaning | + | × | − | ÷ |
Now replacing the sign from left to right using BODMAS Rule, we get:
⇒ (8 × 4 + 3) ÷ 7 = 33 ÷ 11 + ?
⇒ (32 + 3) ÷ 7 = 3 + ?
⇒ 35 ÷ 7 = 3 + ?
⇒ 5 = 3 + ?
⇒ ? = 5 - 3 = 2.
Hence, the correct option is "Option 2".

Which two signs should be interchanged to make the following equation correct?
32 × 5 + 12 ÷ 4 - 18 = 29
÷ and ×
Correct answer
Why this answer is correct
Given equation: 32 × 5 + 12 ÷ 4 - 18 = 29
Option 1) ÷ and ×
Two signs need to be interchanged then:
⇒ 32 ÷ 5 + 12 × 4 - 18 = 29
⇒ 6.4 + 12 × 4 - 18 = 29
⇒ 6.4 + 48 - 18 = 29
⇒ 54.4 - 18 = 29
⇒ 36.4 ≠ 29
Option 2) - and ×
Two signs need to be interchanged then:
⇒ 32 - 5 + 12 ÷ 4 × 18 = 29
⇒ 32 - 5 + 3 × 18 = 29
⇒ 32 - 5 + 54 = 29
⇒ 86 - 5 = 29
⇒ 81 ≠ 29
Option 3) - and +
Two signs need to be interchanged then:
⇒ 32 × 5 - 12 ÷ 4 + 18 = 29
⇒ 32 × 5 - 3 + 18 = 29
⇒ 160 - 3 + 18 = 29
⇒ 178 - 3 = 29
⇒ 175 ≠ 29
Option 4) + and ×
Two signs need to be interchanged then:
⇒ 32 + 5 × 12 ÷ 4 - 18 = 29
⇒ 32 + 5 × 3 - 18 = 29
⇒ 32 + 15 - 18 = 29
⇒ 47 - 18 = 29
⇒ 29 = 29
Hence, the correct answer is "+ and ×".
1, 2, 3, 4, 5 and 6 are written on different faces of a dice. Three different positions of the same dice are shown below. Find the number on the face opposite to the one showing '1'.
4
2
6
5
Correct answer
5
Why this answer is correct
To find the opposite surface of '1', we need to compare the common surface in the given dices,
So, From Dice 1 and Dice 2,
From both dices, 5 is common and on the same surface. So, all remaining surface will be opposite to each other.
5→1
3→4
6→2
So, 5 will be opposite to 1.
Hence, the correct answer is "5".

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 from commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All Tears are Salts.
Some Tears are Crocodiles.
Conclusions:
I. All Crocodiles are Tears.
II. All Crocodiles are Salts.
Neither conclusion I nor II follows.
Only conclusion I follows.
Both conclusions I and II follow.
Only conclusion II follows.
Correct answer
Neither conclusion I nor II follows.
Why this answer is correct
Statements:
All Tears are Salts.
Some Tears are Crocodiles.
The least possible Venn diagram is as follows:
Conclusions:
I. All Crocodiles are Tears. - False (because Some Tears are Crocodiles given. So, All Crocodiles are Tears can be possible but not definite)
II. All Crocodiles are Salts. - False (because Some Tears are Crocodiles and All Tears are Salts given. So, All Crocodiles are Salts can be possible but not definite)
Hence, the correct answer is "Neither conclusion I nor II follows".
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 its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/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)
(2, 14, 3),(4, 28, 5)
(7, 37, 2)
(7, 45, 2)
(7, 22, 2)
(7, 39, 2)
Correct answer
(7, 22, 2)
Why this answer is correct
The logic followed here is:
Logic: (1st number × 3rd number) + 8 = 2nd number.
Now,
For (2, 14, 3):
⇒ (2 × 3) + 8
= 6 + 8 = 14.
For (4, 28, 5)
⇒ (4 × 5) + 8
= 20 + 8 = 28.
Similarly, for Option 3: (7, 22, 2)
⇒ (7 × 2) + 8
= 14 + 8 = 22.
Hence, the correct answer is Option 3.
