France is a lovely country and Japan is a tall tower.
What is the total number of words that begin with a consonant?
A.4
B.6
C.5
D.7
Solution
Consonant-initial words
List the words: France, is, a, lovely, country, and, Japan, is, a, tall, tower.
Words beginning with a consonant: France, lovely, country, Japan, tall, tower.
(is, a, and begin with vowels.)
Count = 6 — option (b).
2
Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
JFJ, MJP, PNV, SRB, ?
A.VHA
B.VVH
C.VVJ
D.VAH
Solution
Letter series (+3, +4, +6)
1st letters: J, M, P, S — +3 each ⇒ next is V.
2nd letters: F, J, N, R — +4 each ⇒ next is V.
3rd letters: J, P, V, B — +6 each (cyclic) ⇒ next is H.
Hence VVH — option (b).
3
Choose the address that is exactly the same as the one given below.
B-24, Green Valley Apartments, Shastri Nagar, Jaipur, Rajasthan - 302015
A.B-24, Green Valley Apartment, Shastree Nagar, Jaipur, Rajasthan - 302015
B.B-24, Green Valley Apartments, Shastri Nager, Jaipur, Rajasthan - 302019
C.B24, Green Valley Apartments, Shastri Nagar, Jaipur, Rajasthan - 302105
D.B-24, Green Valley Apartments, Shastri Nagar, Jaipur, Rajasthan - 302015
Solution
Address matching
(a) drops the s in 'Apartments' and writes 'Shastree'.
(b) writes 'Nager' and PIN 302019; (c) drops the hyphen (B24) and gives PIN 302105.
Only (d) matches every character.
Hence option (d).
4
Select the letter-cluster from among the given options that can replace the question mark (?) in the following series:
SCEG, SFKP, ?, SLWH, SOCQ
A.SIQY
B.SOBQ
C.SPCR
D.SPDR
Solution
Letter series (+3, +6, +9)
The first letter S is constant.
2nd letters: C, F, I, L, O — +3 each ⇒ the missing one is I.
3rd letters: E, K, Q, W, C — +6 each ⇒ Q; 4th letters: G, P, Y, H, Q — +9 each ⇒ Y.
Hence SIQY — option (a).
5
A statement is given followed by two conclusions. Find which conclusion is TRUE based on the given statement.Statement: B = F ≤ H < K ≥ N; R ≥ K < P; H ≥ F
Conclusions:
I: F < N
II: B < R
A.Only II
B.Only I
C.Either I or II
D.Neither I nor II
Solution
Coded inequality
For I: F ≤ H < K ≥ N — the signs between F and N point in opposite directions, so no definite relation ⇒ I is false.
For II: B = F ≤ H < K and R ≥ K, so B < K ≤ R.
That gives B < R definitely ⇒ II is true.
Hence Only II — option (a).
6
Complete the pattern: 12, 36, 80, 150, 252, ?
A.350
B.380
C.392
D.390
Solution
Series n²(n+1)
Write each term as n² × (n+1): 2²×3 = 12, 3²×4 = 36, 4²×5 = 80.
5²×6 = 150 and 6²×7 = 252 ✓.
Next: 7² × 8 = 49 × 8.
= 392 — option (c).
7
Find the odd one out:
A.30 # 5 = 5
B.12 # 2 = 6
C.24 # 4 = 6
D.18 # 3 = 6
Solution
Odd one — division
Rule: first number ÷ second number = third number.
12÷2 = 6 ✓, 24÷4 = 6 ✓, 18÷3 = 6 ✓.
But 30÷5 = 6, not 5 ✗.
Hence option (a).
8
Identify the assumptions that must hold for the statement to be valid, then choose the correct option.Statement: The growing use of artificial intelligence in healthcare has the potential to greatly improve diagnostics and patient care, but it also brings up questions about privacy and data security.
Assumptions:
I. AI in healthcare can potentially improve diagnostics and patient care.
II. Privacy and data security concerns naturally arise with advanced AI applications.
III. The benefits of AI in healthcare outweigh the privacy and security concerns.
A.Only I and II are Implicit
B.Only II and III are implicit
C.Only I is implicit
D.All I, II and III are implicit
Solution
Statement — assumptions
The statement itself claims AI can improve diagnostics and care — I is implicit.
It says such use raises privacy and data-security questions — II is implicit.
III weighs benefits against risks; the statement never makes that comparison.
Hence Only I and II — option (a).
9
Read the following statement carefully and identify the conclusion that follows.Statement: The bank has launched a fingerprint-based authentication system.
Conclusions:
I. The bank aims to enhance security.
II. Customers are required to carry special ID cards.
A.Only Conclusion I follows
B.Only Conclusion II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Statement — conclusions
Biometric authentication is introduced precisely to make access safer — I follows.
Fingerprints REPLACE the need for cards; nothing suggests special ID cards — II does not follow.
So only the first conclusion holds.
Hence option (a).
10
Find the group of letters that best completes the analogy. Use alphabetical positions and reverse position logic where necessary.
BDEM : YWVN :: ACFL : ?
A.ZXMN
B.ZXMU
C.ZXUO
D.ZXUN
Solution
Opposite letters
Each letter is replaced by its OPPOSITE letter (positions add up to 27).
B(2) → Y(25), D(4) → W(23), E(5) → V(22), M(13) → N(14) ✓.
ACFL: A(1) → Z(26), C(3) → X(24), F(6) → U(21), L(12) → O(15).
Hence ZXUO — option (c).
11
Read the following statement carefully and identify the conclusion that follows.Statement:
Some animals are omnivores.
Some omnivores are wild.
Conclusions:
I. Some animals are wild.
II. All wild are animals.
A.Only I follows
B.Only II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Syllogism
Two particular ("some") statements can never give a definite conclusion.
The wild omnivores need not be the same omnivores that are animals — I is uncertain.
II makes a universal claim, which is far beyond the given data.
Hence Neither follows — option (d).
12
In the following question, select the word which cannot be formed using the letters of the given word.
CONSERVATION
A.SESSION
B.CARTON
C.NATION
D.RAVEN
Solution
Word formation — CONSERVATION
CONSERVATION contains only ONE S.
SESSION needs three S letters — impossible.
CARTON, NATION and RAVEN can all be formed from the available letters.
Hence SESSION — option (a).
13
The 5th term of a geometric progression (GP) is 162. The first term is 2.0. What is the common ratio (CR)?
A.3.0
B.2.0
C.2.5
D.2.2
Solution
GP — common ratio
In a GP the 5th term = a × r⁴.
2.0 × r⁴ = 162 ⇒ r⁴ = 81.
r = ⁴√81 = 3.
Hence 3.0 — option (a).
14
Find the odd one out from the given alternatives:
A.Bhagat Singh
B.Chandrashekhar Azad
C.Rajguru
D.Sachin Tendulkar
Solution
Freedom fighters
Bhagat Singh, Chandrashekhar Azad and Rajguru were revolutionary freedom fighters.
Sachin Tendulkar is a cricketer.
He belongs to a different category.
Hence option (d).
15
M is the mother of N. N is the sister of O. How is M related to O?
A.Aunt
B.Mother
C.Grandmother
D.Cousin
Solution
Blood relation
N and O are siblings (N is O’s sister).
So they share the same mother.
M, being N’s mother, is also O’s mother.
Hence option (b).
16
In a certain code language, each letter is assigned a unique digit. Based on the following codes:
HOUSE is coded as 52691 and CAT as 374, how is USE coded?
A.569
B.691
C.6915
D.519
Solution
Letter–digit code
From HOUSE = 52691: H = 5, O = 2, U = 6, S = 9, E = 1.
Pick the digits for U, S and E.
U = 6, S = 9, E = 1.
= 691 — option (b).
Number puzzle (aᵇ)
Rule: the second number is the POWER of the first.
6² = 36 ✓ and 5³ = 125 ✓.
So 4 # 2 = 4².
= 16 — option (d).
19
In a code language, CHAIR is written as DKBJS. How will TABLE be written?
A.UDCMF
B.UDMFC
C.UDMFD
D.UDMED
Solution
Coding (+1, +3, +1, +1, +1)
Decode CHAIR → DKBJS: C+1 = D, H+3 = K, A+1 = B, I+1 = J, R+1 = S.
The shifts by position are +1, +3, +1, +1, +1.
TABLE: T+1 = U, A+3 = D, B+1 = C, L+1 = M, E+1 = F.
Hence UDCMF — option (a).
20
A store sells pens at ₹8 each and notebooks at ₹25 each. If a customer buys 5 pens and 3 notebooks, what's the total bill?
A.₹89
B.₹115
C.₹100
D.₹110
Solution
Total bill
Pens: 5 × 8 = ₹40.
Notebooks: 3 × 25 = ₹75.
Total = 40 + 75.
= ₹115 — option (b).
21
P + Q means P is the mother of Q, P ÷ Q means P is the father of Q, P − Q means P is the sister of Q, P × Q means P is the brother of Q.
What does X ÷ Y − Z mean?
A.X is Z's uncle
B.Y is Z's mother
C.X is Z's father
D.Z is X's mother
Solution
Coded relations
X ÷ Y means X is the father of Y.
Y − Z means Y is the sister of Z, so Y and Z share the same parents.
Hence X is also the father of Z.
X is Z’s father — option (c).
22
If '×' = '−', '+' = '÷', '−' = '+', '÷' = '×', then which is valid?
A.10+5−3×2=3
B.15÷3+2×1=20
C.8×4−2+6=12
D.9−3+6÷2=12
Solution
Symbol substitution
Test option (a): 10+5−3×2 becomes 10 ÷ 5 + 3 − 2.
BODMAS: 10 ÷ 5 = 2.
2 + 3 − 2 = 3 = RHS ✓ (the other options do not balance).
Hence option (a).
23
If 'A' means '−', 'B' means '÷', 'C' means '+', and 'D' means '×', what is the value of the following expression?
35 B 7 C 4 D 3 A 5 = ?
List the words: France, is, a, lovely, country, and, Japan, is, a, tall, tower.
Words beginning with a consonant: France, lovely, country, Japan, tall, tower.
(is, a, and begin with vowels.)
Count = 6 — option (b).
1st letters: J, M, P, S — +3 each ⇒ next is V.
2nd letters: F, J, N, R — +4 each ⇒ next is V.
3rd letters: J, P, V, B — +6 each (cyclic) ⇒ next is H.
Hence VVH — option (b).
The first letter S is constant.
2nd letters: C, F, I, L, O — +3 each ⇒ the missing one is I.
3rd letters: E, K, Q, W, C — +6 each ⇒ Q; 4th letters: G, P, Y, H, Q — +9 each ⇒ Y.
Hence SIQY — option (a).
For I: F ≤ H < K ≥ N — the signs between F and N point in opposite directions, so no definite relation ⇒ I is false.
For II: B = F ≤ H < K and R ≥ K, so B < K ≤ R.
That gives B < R definitely ⇒ II is true.
Hence Only II — option (a).
Write each term as n² × (n+1): 2²×3 = 12, 3²×4 = 36, 4²×5 = 80.
5²×6 = 150 and 6²×7 = 252 ✓.
Next: 7² × 8 = 49 × 8.
= 392 — option (c).
Rule: first number ÷ second number = third number.
12÷2 = 6 ✓, 24÷4 = 6 ✓, 18÷3 = 6 ✓.
But 30÷5 = 6, not 5 ✗.
Hence option (a).
Each letter is replaced by its OPPOSITE letter (positions add up to 27).
B(2) → Y(25), D(4) → W(23), E(5) → V(22), M(13) → N(14) ✓.
ACFL: A(1) → Z(26), C(3) → X(24), F(6) → U(21), L(12) → O(15).
Hence ZXUO — option (c).
Two particular ("some") statements can never give a definite conclusion.
The wild omnivores need not be the same omnivores that are animals — I is uncertain.
II makes a universal claim, which is far beyond the given data.
Hence Neither follows — option (d).
In a GP the 5th term = a × r⁴.
2.0 × r⁴ = 162 ⇒ r⁴ = 81.
r = ⁴√81 = 3.
Hence 3.0 — option (a).
N and O are siblings (N is O’s sister).
So they share the same mother.
M, being N’s mother, is also O’s mother.
Hence option (b).
From HOUSE = 52691: H = 5, O = 2, U = 6, S = 9, E = 1.
Pick the digits for U, S and E.
U = 6, S = 9, E = 1.
= 691 — option (b).
Rule: the second number is the POWER of the first.
6² = 36 ✓ and 5³ = 125 ✓.
So 4 # 2 = 4².
= 16 — option (d).
Decode CHAIR → DKBJS: C+1 = D, H+3 = K, A+1 = B, I+1 = J, R+1 = S.
The shifts by position are +1, +3, +1, +1, +1.
TABLE: T+1 = U, A+3 = D, B+1 = C, L+1 = M, E+1 = F.
Hence UDCMF — option (a).
X ÷ Y means X is the father of Y.
Y − Z means Y is the sister of Z, so Y and Z share the same parents.
Hence X is also the father of Z.
X is Z’s father — option (c).
