Ans: (c) 159
Let's analyze the numbers quickly:

250: Ends in 0 (divisible by 5).

95: Ends in 5 (divisible by 5).

159: Ends in 9 (not divisible by 5).

150: Ends in 0 (divisible by 5).

Three numbers (250, 95, and 150) are divisible by 5, but 159 is not.

So, the odd one out is: (c) 159

Ans: (b) KN
Let's look at the differences between the letters in each pair:

(a) HL: H (8) to L (12) → Difference is 4.

(b) KN: K (11) to N (14) → Difference is 3.

(c) CG: C (3) to G (7) → Difference is 4.

(d) UY: U (21) to Y (25) → Difference is 4.

Pairs (a), (c), and (d) have a difference of 4, while pair (b) has a difference of 3.

So, the odd one out is: (b) KN

Ans: (d) Calm
Let's look at the nature of each word:

Joy: A positive emotion.
Fear: A negative emotion.

Anger: A negative emotion.

Calm: A positive emotion, but often seen as a neutral or balanced state rather than an intense emotion like joy.

Three words (Fear, Anger, and Joy) represent strong emotional states, while "Calm" represents a more neutral or balanced state.

Thus, the odd one out is: (d) Calm

Ans: (d) 94
Let's analyze each number:

158: Sum of digits = 1 + 5 + 8 = 14

77: Sum of digits = 7 + 7 = 14

86: Sum of digits = 8 + 6 = 14

94: Sum of digits = 9 + 4 = 13

Three numbers (158, 77, and 86) have the sum of their digits equal to 14, while 94 has a sum of 13.

So, the odd one out is: (d) 94

Ans: (c) Jewellery
Let's analyze the words:

Necklace: A specific type of jewelry worn around the neck.

Bracelet: A specific type of jewelry worn around the wrist.

Jewellery: A general term for decorative items worn for personal adornment, including necklaces, bracelets, etc.

Anklet: A specific type of jewelry worn around the ankle.

Three words (Necklace, Bracelet, Anklet) are specific types of jewelry, while "Jewellery" is a broad category that includes all these items.

Thus, the odd one out is: (c) Jewellery

Ans: (b) 56
Let's analyze each number:

107: Odd number.

56: Even number.

61: Odd number.

81: Odd number.

Three numbers (107, 61, and 81) are odd, while 56 is even.

So, the odd one out is: (b) 56

Ans: (d) Friend
Let's analyze the relationships:

(a) Brother : A family member.

(b) Sister : A family member.

(c) Uncle : A family member.

(d) Friend : Not a family member (typically).

Three words (Brother, Sister, Uncle) represent family members, while "Friend" does not.

Thus, the odd one out is: (d) Friend

Ans: (a) 11
Let's analyze each number:

11: Prime number.

18: Not a prime number (divisible by 1, 2, 3, 6, 9, 18).

80: Not a prime number (divisible by 1, 2, 4, 5, 8, 10, 16, 20, 40, 80).

39: Not a prime number (divisible by 1, 3, 13, 39).

Three numbers (18, 80, and 39) are not prime, while 11 is a prime number.

So, the odd one out is: (a) 11

Ans: (b) Saw : Carpenter
Let's analyze each pair:
(a) Chef : Knife : A chef uses a knife as a tool.

(b) Saw : Carpenter : A carpenter uses a saw as a tool.

(c) Sculptor : Chisel : A sculptor uses a chisel as a tool.

(d) Doctor : Stethoscope : A doctor uses a stethoscope as a tool.

In three pairs (a, b, and c), the first word is a profession and the second word is a specific tool used by that profession. However, in pair (b), the order is reversed: "Saw" is the tool and "Carpenter" is the profession.

Thus, the odd one out is: (b) Saw : Carpenter

Ans: (d) 31 - 35
Let's analyze each pair of numbers:
(a) 23 - 29: Both 23 and 29 are prime numbers.
(b) 11 - 13: Both 11 and 13 are prime numbers.
(c) 11 - 17: Both 11 and 17 are prime numbers.
(d) 31 - 35: 31 is a prime number, but 35 is not (35 = 5 × 7).
In pairs a, b, and c, both numbers in each pair are prime numbers. However, in pair d, one number (35) is not a prime number.
Thus, the odd one out is: (d) 31 - 35

Ans: (d) FGJK
Let's analyze the sequence of letters in each option:

(a) KMPT

• K to M: +2
• M to P: +3
• P to T: +4

(b) BDGK

• B to D: +2
• D to G: +3
• G to K: +4

(c) PRUY

• P to R: +2
• R to U: +3
• U to Y: +4

(d) FGJK

• F to G: +1 (should be +2)
• G to J: +3
• J to K: +1 (should be +4)

In options a, b, and c, the pattern is consistent: the first letter to the second letter has a difference of 2, the second to the third has a difference of 3, and the third to the fourth has a difference of 4.
However, in option d, the differences are inconsistent with this pattern.
Thus, the odd one out is: (d) FGJK

Ans: (a) NPR
Let's analyze the sequence of letters in each option:
(a) NPR

• N to P: +2
• P to R: +2

(b) RQP

• R to Q: -1
• Q to P: -1

(c) HGF

• H to G: -1
• G to F: -1

(d) DCB

• D to C: -1
• C to B: -1

In options b, c, and d, the pattern is consistent: each letter decreases by 1.

However, in option a, the pattern is different as each letter increases by 2.

Thus, the odd one out is: (a) NPR

Ans: (c) Sap

Let's analyze the meaning and context of each word:
(a) Thrust : To push or drive something forward with force.
(b) Prod : To poke or jab someone or something, often to encourage movement.
(c) Sap : The fluid that circulates in the vascular system of a plant; also can mean to weaken or exhaust.
(d) Jab : A quick, sharp blow or thrust.

Words A (Thrust), B (Prod), and D (Jab) all relate to actions involving pushing, poking, or striking something forcefully.
However, word C (Sap) does not fit this pattern as it primarily refers to plant fluid or weakening something, which is unrelated to the physical action described by the other words.

Thus, the odd one out is: C. Sap

Ans: (d) Computer
Cupboard , Table , and Bed are all types of furniture.

Computer is an electronic device, not a type of furniture.

So, the option that doesn't belong to the group is: (d) Computer .

Ans: (d) 65
15 = (4)² – 1
48 = (7)² –1
35 = (6)² – 1
But, 65 = (8)² + 1
So, the number that does not fit the pattern (d) 65
