Questions

Q1

Four words have been given out of which three are alike in some manner, while the fourth one is different. Choose the odd one out -

  1. (1)Feeling
  2. (2)Joy
  3. (3)Anxiety
  4. (4)Anger

Answer: (1) Feeling

Explanation

Joy, anxiety and anger are particular emotions, while 'feeling' is the general word for all of them, so it is the odd one.

Q2

Choose the odd pair of words -

  1. (1)Cow : Calf
  2. (2)Dog : Bitch
  3. (3)Lion : Cub
  4. (4)Tortoise : Baby tortoise

Answer: (2) Dog : Bitch

Explanation

Cow : Calf, Lion : Cub and Tortoise : Baby tortoise are parent and young, while Dog : Bitch is male and female, so it is the odd pair.

Q3

Which one is different among the following?

  1. (1)WhatsApp
  2. (2)Skype
  3. (3)Snapchat
  4. (4)Linkedin

Answer: (4) Linkedin

Explanation

WhatsApp, Skype and Snapchat are apps for messaging and calls, while LinkedIn is a professional networking site, so it is different.

Q4

Which of the following does not belong to the group?

  1. (1)ZA
  2. (2)XC
  3. (3)VE
  4. (4)MG

Answer: (4) MG

Explanation

Add the letters' places in the alphabet: Z + A = 26 + 1 = 27, X + C = 24 + 3 = 27 and V + E = 22 + 5 = 27, but M + G = 13 + 7 = 20. So MG does not belong.

Q5

Find the odd one out: 626, 254, 878, 646

  1. (1)626
  2. (2)254
  3. (3)878
  4. (4)646

Answer: (2) 254

Explanation

626, 878 and 646 read the same from left to right and from right to left (palindromes), but 254 reversed is 452. All four are even numbers, so evenness cannot be the basis.

Q6

Find the odd one out: BD, CF, DH, EK

  1. (1)BD
  2. (2)CF
  3. (3)DH
  4. (4)EK

Answer: (4) EK

Explanation

In BD, CF and DH the second letter's place in the alphabet is double the first letter's (2 → 4, 3 → 6, 4 → 8); E is 5th, so the pair should be EJ (10), not EK (11). A rule of equal gaps does not fit, since the gaps are 2, 3 and 4.

Q7

Choose the odd pair: Rich : Poor, Ancient : Modern, Generous : Miserly, Brave : Courageous

  1. (1)Rich : Poor
  2. (2)Ancient : Modern
  3. (3)Generous : Miserly
  4. (4)Brave : Courageous

Answer: (4) Brave : Courageous

Explanation

Rich–Poor, Ancient–Modern and Generous–Miserly are pairs of opposite words (antonyms), but Brave and Courageous mean the same (synonyms). All eight words are adjectives, so the kind of word cannot be the basis.

Q8

Four words are given; three are alike in some way and one is different. Choose the odd one out: Hockey, Cricket, Chess, Football

  1. (1)Hockey
  2. (2)Cricket
  3. (3)Chess
  4. (4)Football

Answer: (3) Chess

Explanation

Hockey, cricket and football are outdoor field games played by two teams with a ball, while chess is an indoor board game for two players with no ball. 'Played between two sides' cannot be the basis, because all four games have two sides.

Q9

Choose the odd one out: Jackal, Tiger, Lion, Leopard

  1. (1)Jackal
  2. (2)Tiger
  3. (3)Lion
  4. (4)Leopard

Answer: (1) Jackal

Explanation

The tiger, lion and leopard are big cats of the cat family (Felidae, genus Panthera), while the jackal belongs to the dog family (Canidae). All four are wild flesh-eating mammals, so being a carnivore cannot be the basis.

Q10

Find the odd one out: 28, 56, 75, 91

  1. (1)28
  2. (2)56
  3. (3)75
  4. (4)91

Answer: (3) 75

Explanation

28 = 7 × 4, 56 = 7 × 8 and 91 = 7 × 13 are all multiples of 7, but 75 (3 × 5 × 5) is not. 91 only looks like a prime number; it is 7 × 13.

Q11

One term of the series 1, 8, 9, 64, 25, 196, 49 is wrong. Find the wrong term.

  1. (1)196
  2. (2)64
  3. (3)25
  4. (4)49

Answer: (1) 196

Explanation

The terms in odd places are squares of odd numbers (1², 3², 5², 7²) and those in even places are cubes of even numbers (2³ = 8, 4³ = 64, 6³ = 216). So the sixth term should be 216, not 196. 196 looks right because it is a perfect square (14²), but the even places hold cubes, not squares.

Q12

Find the odd one out: April, June, September, October

  1. (1)April
  2. (2)June
  3. (3)October
  4. (4)September

Answer: (3) October

Explanation

April, June and September have 30 days each, but October has 31 days. The month's length is the only feature that separates them, since all four are months of the Gregorian calendar.

Q13

Find the odd one out: Square, Rectangle, Rhombus, Triangle

  1. (1)Square
  2. (2)Rectangle
  3. (3)Rhombus
  4. (4)Triangle

Answer: (4) Triangle

Explanation

A square, a rectangle and a rhombus are quadrilaterals with four sides, but a triangle has only three sides. The square is not the odd one: it is a special rectangle and also a special rhombus.
