Consider the following statement and choose the option that follows.Statement: The government launched a new scheme to promote solar rooftop installations in urban areas.
Conclusions:
I. The government aims to increase the use of renewable energy sources.
II. The scheme will completely replace traditional energy systems.
A.Only I follows
B.Only II follows
C.Both follow
D.Neither follows
Solution
Statement — conclusions
Promoting solar rooftops is clearly a step towards renewable energy — I follows.
II claims a COMPLETE replacement of traditional energy, which one scheme cannot ensure.
Solar power supplements, not replaces, the existing grid.
Hence Only I — option (a).
Interchange two signs to correct the equation.
60 ÷ 5 + 8 − 6 × 2 = 58
A.÷ and −
B.+ and −
C.÷ and ×
D.− and ×
Solution
Interchange signs
Interchange − and × : the equation becomes 60 ÷ 5 + 8 × 6 − 2.
BODMAS: 60 ÷ 5 = 12 and 8 × 6 = 48.
12 + 48 − 2 = 58 ✓ — it matches the right-hand side.
Hence − and × — option (d).

Solve: GI : JL :: AC : ?
A.KM
B.DF
C.LN
D.MO
Solution
Analogy (+3)
G(7) + 3 = J(10) and I(9) + 3 = L(12).
So each letter moves three places forward.
A(1) + 3 = D(4) and C(3) + 3 = F(6).
Hence DF — option (b).
Read the following statement carefully and identify the action that follows.Statement: Many students find it difficult to manage time during examinations.
Course of Action:
I. Conduct workshops on time management skills.
II. Cancel all examinations to reduce stress.
A.Only 1 follows
B.Only 2 follows
C.Both follow
D.Neither follows
Solution
Course of action
Training students in time management addresses the problem directly — I follows.
Cancelling all examinations is drastic and destroys the assessment system itself.
A course of action must solve the problem without creating a bigger one.
Hence Only 1 — option (a).
9
Identify the odd one out:
A.12 % 3 = 4
B.18 % 3 = 6
C.9 % 2 = 4
D.21 % 7 = 3
Solution
Odd one — division
Rule: a % b means a ÷ b.
12÷3 = 4 ✓, 18÷3 = 6 ✓, 21÷7 = 3 ✓.
But 9 ÷ 2 = 4.5, not 4 ✗.
Hence option (c).
10
Read the given information carefully and answer the question asked below.
Seven people — Arun, Bhoomi, Charu, Dinu, Elena, Faruk and Garima — live on seven different floors of a building, but not necessarily in the same order. The lowermost floor is numbered 1 and the topmost floor 7.
Arun does not live on the topmost floor. Bhoomi lives immediately below Faruk. Charu lives on an even-numbered floor. Three people live between Faruk and Charu. The number of people living between Faruk and Dinu is equal to the number of people living between Dinu and Charu. More than four people live between Elena and Garima. Bhoomi lives on one of the floors below Garima.
Who among the following lives two floors below Arun?
A.Bhoomi
B.Charu
C.Elena
D.Dinu
Solution
Floor puzzle
Charu is on an even floor with three people between Faruk and Charu; with Bhoomi immediately below Faruk, the set fits as Charu 2, Bhoomi 5, Faruk 6.
Dinu must be equidistant from Faruk and Charu, so Dinu takes floor 4.
More than four people between Elena and Garima puts Elena on 1 and Garima on 7, leaving floor 3 for Arun.
Two floors below Arun (3) is floor 1 — Elena, option (c).
11
Read the following statements carefully and identify the conclusion that follows.Statements:
All fruits are healthy.
All apples are fruits.
Conclusions:
I. All apples are healthy.
II. All healthy are fruits.
A.Only I follows
B.Only II follows
C.Both follow
D.Neither follows
Solution
Syllogism
All apples are fruits and all fruits are healthy, so all apples are healthy — I follows.
II reverses the relation; healthy things may include much more than fruits.
A universal statement cannot simply be turned around.
Hence Only I — option (a).
12
Find the odd one out:
Cylinder, Triangle, Rectangle, Pentagon, Square
A.Rectangle
B.Triangle
C.Pentagon
D.Cylinder
Solution
2-D vs 3-D
Triangle, rectangle, pentagon and square are all plane (2-D) figures.
A cylinder is a solid, three-dimensional shape.
So it belongs to a different category.
Hence option (d).
13
In each of the following questions, a specific letter-to-letter coding pattern is applied to the first word to obtain the second word. Apply the same pattern to the third word and choose the correct option.
xyyzzy : cbbaab :: xxyzyy : ?
A.abbacc
B.bbacca
C.abbcca
D.ccbabb
Solution
Letter-to-letter code
Compare xyyzzy with cbbaab position by position: x → c, y → b and z → a.
These are opposite letters (x is 24th, c is 3rd; y is 25th, b is 2nd; z is 26th, a is 1st).
Applying the same map to xxyzyy: c, c, b, a, b, b.
= ccbabb — option (d).
14
If TICKET becomes TTECIK, how is OFFICE written?
A.IEFFCO
B.IECFFO
C.OFCFEI
D.OECFFI

TICKET → T (1), T (6), E (5), C (3), I (2), K (4) = TTECIK ✓.
OFFICE → O (1), E (6), C (5), F (3), F (2), I (4).
= OECFFI — option (d).
15
Find the odd one out from the given alternatives:
A.SBI
B.PNB
C.BOI
D.GDP
Solution
Banks vs concept
SBI, PNB and BOI are all public sector BANKS.
GDP — Gross Domestic Product — is an economic concept.
So it belongs to a different category.
Hence option (d).
16
Which of the following words is formed by changing exactly one letter at one place in the word "REPLACE"?
A.REPLATE
B.RELEASE
C.RESPECT
D.RECLINE
Solution
One-letter change

9, 18, 37, 72, 144, 288
A.37
B.18
C.72
D.288
Solution
Wrong term in series
Each term should be double the previous: 9, 18, 36, 72, 144, 288.
The series shows 37 in place of 36.
Every other term follows the ×2 rule.
So 37 is the incorrect number — option (a).

The same 25 questions, but with a timer and the answers hidden — 15 minutes.
Rule: a + b means a² + b².
Check: 5² + 4² = 25 + 16 = 41 ✓; 4² + 3² = 16 + 9 = 25 ✓.
3 + 2 = 3² + 2² = 9 + 4.
= 13 — option (a).
Interchange − and × : the equation becomes 60 ÷ 5 + 8 × 6 − 2.
BODMAS: 60 ÷ 5 = 12 and 8 × 6 = 48.
12 + 48 − 2 = 58 ✓ — it matches the right-hand side.
Hence − and × — option (d).
M is N’s son, so M is one generation below N.
L is M’s daughter — one more generation down.
So L is N’s granddaughter.
Hence option (c).
Riya's mother's daughter is Riya's sister.
The man is that sister’s husband.
A sister’s husband is one’s brother-in-law.
Hence option (b).
G(7) + 3 = J(10) and I(9) + 3 = L(12).
So each letter moves three places forward.
A(1) + 3 = D(4) and C(3) + 3 = F(6).
Hence DF — option (b).
Each term = previous × 3 + 1.
1×3+1 = 4, 4×3+1 = 13, 13×3+1 = 40 ✓.
Next: 40 × 3 + 1 = 120 + 1.
= 121 — option (a).
Rule: a % b means a ÷ b.
12÷3 = 4 ✓, 18÷3 = 6 ✓, 21÷7 = 3 ✓.
But 9 ÷ 2 = 4.5, not 4 ✗.
Hence option (c).
Charu is on an even floor with three people between Faruk and Charu; with Bhoomi immediately below Faruk, the set fits as Charu 2, Bhoomi 5, Faruk 6.
Dinu must be equidistant from Faruk and Charu, so Dinu takes floor 4.
More than four people between Elena and Garima puts Elena on 1 and Garima on 7, leaving floor 3 for Arun.
Two floors below Arun (3) is floor 1 — Elena, option (c).
All apples are fruits and all fruits are healthy, so all apples are healthy — I follows.
II reverses the relation; healthy things may include much more than fruits.
A universal statement cannot simply be turned around.
Hence Only I — option (a).
