Step-by-step Solution and Explanation of The Railway Competitive Exam Test
Question 26
P, Q, R, S, T, U and V sit around a circular table facing the centre. V sits to the immediate left of T. U sits to the immediate left of R. R sits second to the left of S. Q sits third to the left of T. Who sits 2nd to the right of S?
A. P
B. R
C. T
D. U
Circular Seating Arrangement
Given:
7 seats: P,Q,R,S,T,U,V
left of = anti-clockwise
right of = clockwise
Cicular means: 1,2,3,4,5,6,7,1,…
Let’s start.
1 = V
2 = T
3 = P
4 = U
5 = R
6 = Q
7 = S
– V left of T: So consider V as 1 and T as 2.
– U left of R: Unsure about it, so wait.
– R 2nd left of S: unsure so wait.
– Q 3rd left of T: T as 2. Left side means 6, 7, 1, 2. Q as 6.
– Go back to R and S: It is impossible to put R and S in any position besides 7 and 5, because of condition.
– U left of R, so U as 4.
– Only 3 left for P.
But in real exam the question asked 2nd right of S. So the moment we found S as 7, we can stop and fill the answer.
S (7), V (1), T (2).
β
Answer: C. T
Question 27
There are 72 members in group A, 12 members in group B and 87 members in group C. All the members of these groups went to a restaurant. The average amounts spent on each member of groups A, B and C are βΉ404, βΉ316 and βΉ424, respectively. The overall average amount (in βΉ) spent per member is:
A. 404
B. 412
C. 408
D. 409
Weighted Average
Formula:
Total members:Total amount:
β
Answer: C. 408
π Trick: Never average averages β use weighted average.
Shortcut:
Divide by 3 once: 72, 12, 87
We’ll get: 24, 4, 29
24 + 4 + 29 = 57
Divide by 4: 404, 316, 424
We’ll get: 101, 79, 106
Let’s multiply now:
24 Γ 101 + 4 Γ 79 + 29 Γ 106 = 5814
Average: 5814/57 = 102
Now remember, we only bring back the numerator value back, so we divided 404, 316, 424 by 4, right? Now, we will multiply it again by 4 to get the real option.
102 Γ 4 = 408.
Option C.
Question 28
If 160% of 75% of A is equal to two times the value of 150% of B, then A is more/less than B by how much percentage?
A. 150%, less
B. 150%, more
C. 60%, less
D. 60%, more
Percentage Comparison
Given:
160% Γ 75% Γ A = 2 Γ (150% Γ B)
Convert:
1.6 Γ 0.75 Γ A = 2 Γ 1.5 Γ B
1.2A = 3B
β A = 2.5B
So:
A is 150% more than B
β
Answer: B. 150%, more
π Shortcut: Convert to decimal β compare ratio.
Question 29
Which of the following will be the pressure of water at the base of a lake of height 20 metres? (g = 9.8m/s2 and Density of water = 1 kg/litre)
A. 19,600 Pa
B. 196 Pa
C. 1,96,000 Pa
D. 1960 Pa
Pressure Formula
P = pgh
Given:
p = 1000 kg/mΒ³
g = 9.8
h = 20
P = 1000 Γ 9.8 Γ 20
P = 196000 Pa
β
Answer: C. 1,96,000 Pa
π Trick: Water density = 1000 always.
Question 30

Question 31
The internal surface area (in cm2 ) of an open (at the top) cuboidal box whose internal length, breadth and height are 8 cm, 17 cm and 22 cm, respectively, is:
A. 1236
B. 1215
C. 1189
D. 1238
Surface Area (Open Box)
Formula:
= 2(lb + bh + hl) β lb
= 2(8 Γ 17 + 17 Γ 22 + 22 Γ 8) β 8 Γ 17
= 2(136 + 374 + 176) β 136
= 2(686) β 136
= 1372 β 136
= 1236
β
Answer: A. 1236
Trick: Shorten the formula: lb + 2(bh + hl)
8 Γ 17 + 2(17 Γ 22 + 22 Γ 8)
136 + 2(374 + 176)
136 + 1100
1236
Question 32
In this question, a question is followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and decide the appropriate answer.
Q. Five students β Alok, Bharti, Celine, Darpan, and Ema β obtained different marks in an examination. Who scored the third highest marks?
(I) Darpan scored more than Alok and Bharti but less than Celine.
(II) Ema scored more than Darpan but less than Celine.
A. Data in Statement I alone is sufficient to answer the question while data in Statement II is not
B. Data in Statement II alone is sufficient to answer the question while data in Statement I is not
C. Both statements I and II together (and not statement I alone or statement II alone) are sufficient to answer the question
D. Both statements I and II together are NOT sufficient to answer the question
This is a Data Sufficiency + Ranking question. The goal is NOT to find all ranks β only check if we can fix who is 3rd highest.
π΄ Given
Five students: Alok (A), Bharti (B), Celine (C), Darpan (D), Ema (E)
All have different marks.
π§ Statement (I)
βDarpan scored more than Alok and Bharti but less than Celineβ
This gives:
C > D > A,B
π But A and B order is unknown
π Ema is completely unknown
So possible rankings can change β 3rd position not fixed
β Statement (I) alone is NOT sufficient
π§ Statement (II)
βEma scored more than Darpan but less than Celineβ
This gives:
C > E > D
π But A and B are unknown
Again, 3rd place can vary
β Statement (II) alone is NOT sufficient
π₯ Combine (I) + (II)
From (I): C > D > A,B
From (II): C > E > D
π§ Merge both: C > E > D > A,B
Now observe carefully:
A & B = 4th/5th (order doesn’t matter)
C = 1st
E = 2nd
D = 3rd
β
Answer: D. Both statements I and II together (and not statement I alone or statement II alone) are sufficient to answer the question

Three positive integers, A, B, and C, are such that the least common multiple of A and B is 24, the least common multiple of B and C is 36, and the least common multiple of C and A is 72. If the numbers are taken to be as small as possible, the value of A + B + C is:
A. 25
B. 27
C. 29
D. 31
LCM Problem
Given:
LCM(A,B) = 24
LCM(B,C) = 36
LCM(C,A) = 72
Break given LCMs
π So only primes involved are 2 and 3
Think in simple words (NO VARIABLES)
We need to separate A, B, C using 2s and 3s out of the grouped (A, B), (B, C), and (C, A):
For A look (A, B) & (C, A) β 23 came in both (A, B) and (C, A) which confirms it’s A. Only 3 left behind for B.
For C look (B, C) & (C, A) β 32 came in both (B, C) and (C, A) which confirms it’s C. Only 23 left behind for B.
For B look (A, B) & (B, C) β Two values left for B: 22 and 3.
Minimum values:
A=8, B=12, C=9
A + B + C = 29
β
Answer: C. 29
π Trick: Use prime factors.

Question 39
Six years hence, a father’s age will be 3 times the age of his son. Six years ago, the father was 7 times as old as his son. Find the present ages (in years) of the father and son.
A. 50 and 14
B. 46 and 10
C. 52 and 16
D. 48 and 12
Let the present age of the son be and the father be .
Six years hence means after 6 years, so ages become and , and we are told the father will be 3 times the son, so . Six years ago means ages were and , and the father was 7 times the son, so .
Now simplify both: from the first, . From the second, . Since both equal , set them equal: . Solving gives . Substitute back: .
So the present ages are: father = 48 years, son = 12 years.
