Select the number that will replace the question mark (?) in the following series.
12, 2, 24, 3, 72, 4, ?
198
288
336
202
Correct answer
288
Why this answer is correct
The logic follows here is:-
We have to multiply the first term and the second term to get the third term.
12 is the 1st term, 2 is the 2nd term,
12 × 2 = 24
24 × 3 = 72
72 × 4 = 288
Hence, the correct answer is "288".
A student has to obtain 40% of the maximum marks to pass. If she scored 80 marks and yet failed by 20 marks, then what were the maximum marks?
220
250
300
200
Correct answer
250
Why this answer is correct
Let maximum marks = x
Passing marks = 40 % = 0.4 x → (i)
Marks scored = 80
Remaining marks to pass = 20
Passing marks = 80 + 20 = 100 → (ii)
Equation (i) and (ii),
0.4 x = 100
x = 100 / 0.4
x = 1000 / 4
x = 250
Hence, the correct answer is "250".
Alternate Method
Let maximum marks = 100%
Passing marks = 40 %
Marks scored = 80 and failed by 20 marks
40 % = 80 + 20
40 % = 100
1 % = 100 / 40 = 2.5
100 % = 100 * 2.5 = 250
Maximum marks = 250.

The logic follows here is:-
Alternative alphabets are decreasing and increasing by 3.
Similarly,
Hence, the correct answer is "POFGB".
Select the correct combination of the mathematical signs to replace Ys in the below equation and thereby balance it.
16 Y 2 Y 3 Y 6 Y 4
÷, ×, =, -
×, ÷, =, -
÷, ×, =, ×
×, =, -, ÷
Correct answer
÷, ×, =, ×
Why this answer is correct
Given equation is :-
16 Y 2 Y 3 Y 6 Y 4
Placing mathematical signs at the place of Y and using BODMAS rule,
Option 1) → ÷, ×, =, -
16 ÷ 2 × 3 = 6 - 4
8 × 3 = 6 - 4
24 ≠ 2
Option 2) → ×, ÷, =, -
16 × 2 ÷ 3 = 6 - 4
16 × 0.67 = 6 - 4
10.72 ≠ 2
Option 3) → ÷, ×, =, ×
16 ÷ 2 × 3 = 6 × 4
8 × 3 = 6 × 4
24 = 24
Option 4) → ×, =, -, ÷
16 × 2 = 3 - 6 ÷ 4
16 × 2 = 3 - 1.5
32 ≠ 1.5
Hence, the correct answer is "÷, ×, =, ×".
Six soldiers A, B, C, D, E and F are standing in a row next to each other. F is at immediate left to C. F and E are at the extreme ends of the row. C is exactly between F and B. A is at the immediate left of D. E is at the immediate right of D. Which soldier is at the fourth position from the right?
A
B
C
D
Correct answer
B
Why this answer is correct
The sitting arrangement according to the given information is :
Six soldiers A, B, C, D, E, and F are standing in a row next to each other.
Case 1:
Case 2:
2. C is exactly between F and B.
Case 1:
Case 2:
3. E is at the immediate right of D.
Here, case 2 is eliminated.
4. A is at the immediate left of D.
So, soldier B is at the fourth position from the right.
Hence, the correct answer is "B".
In a certain coding language, 'lo re ga' indicates 'Doors Are Locked', 'sa ga pa' indicates 'People Are Angry', 'so du pa' indicates 'People Live Now' and 'bu so' indicates 'Go Now'. What would 'sa so' indicate in that code language?
Are Live
People Live
Angry Now
Are Now
Correct answer
Angry Now
Why this answer is correct
The logic follows here is :
From the above image, we conclude that,
| Word | Code |
|---|---|
| ga | Are |
| pa | People |
| so | Now |
| bu | Go |
| du | Live |
| sa | Angry |
Code for "sa so" is "Angry Now**".**
Hence, the correct answer is "Angry Now**."**
Select the letter cluster that will replace the question mark (?) in the following series.
HB, JE, LH, NK, ?
RM
PN
QN
SO

1st letter of each word is increasing by 2.
2nd letter of each word is increasing by 3.
Hence, the correct answer is "PN".
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:
All chains are glasses.
All glasses are tables.
Conclusions:
I. Some glasses are chains.
II. Some tables are glasses.
Only conclusion II follows
Both conclusions I and II follow
Only conclusion I follows
Neither conclusion I nor II follows
Correct answer
Both conclusions I and II follow
Why this answer is correct
The least possible Venn diagram for the given statements will be :
Conclusions :
I. Some glasses are chains → True (As all chains are glasses so it means some glasses are chains it is definitely true)
II. Some tables are glasses → True (As all glasses are tables it means some tables are glasses it is definitely true)
Hence, the correct answer is "Both conclusions I and II follow".
Additional Information
A policeman stepped out of the police station and walked 60 m towards west. He then took a left turn walked 38 m to reach a fruit shop. He then took a right turn and walked 60 m. He then took a right turn and walked 38 m to reach a restaurant. What is the approximate shortest distance between the police station and the restaurant via the fruit shop?
71 m
150 m
112 m
142 m
Correct answer
142 m
Why this answer is correct
Representing the given information on NESW diagram:
The approximate shortest distance between the police station and the restaurant via the fruit shop is:
Distance = OB + DB
But Here, OB = DB
Then, Distance = 2(OB) → (i)
Applying Pythagoras theorem in ∆OAB :
(Hypotenuse)2 = (Base)2 + (Perpendicular)2
(OB)2 = (AB)2 + (OA)2
(OB)2 = (38)2 + (60)2
(OB)2 = 1444 + 3600 = 5044
OB = √5044 = 71.02
Putting the value of OB in equation (i),
Distance = 2(OB) → 2 × 71.02 → 142.4 (approx. 142)
Hence, the correct answer is "142 m".

Why this answer is correct
The logic follows here is:
So, options 1, 2, and 4 are alike in some manner and option 3 is different.
Hence, the correct answer is "I - O - T - Z".
