Odd One Out (SSC CHSL 2023 Tier 2)

Total Questions: 5

1. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL Tier II (10/01/2024)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding / subtracting / multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: (b) 31 - 280
Solution:The logic followed here is :

(1st number) × 9 = (2nd number)
(14 - 126) → 14 × 9 = 126
(25 - 225) → 25 × 9 = 225
(12 - 108) → 12 × 9 = 108
But, (31 - 280) → 31 × 9 = 279 (Not 280)

Hence, 31 - 280 is the odd one.

2. Three of the following four word pairs are alike and thus form a group. Select the word pair that does NOT belong to that group. [S.S.C CHSL Tier II (10/01/2024)]

Correct Answer: (d) Rice - eat
Solution:The relationship between each pair:
Water - bottles → Bottles are used to store water.
Clothes - wardrobes → Wardrobes are used to store clothes.
Money - wallets → Wallets are used to store money.
Rice - eat → This pair does not follow the storage relationship; instead, it represents an action (eating rice).
The first three pairs involve a storage relationship, while the fourth pair represents an action.
Hence, Rice - eat is the correct answer.

3. Three of the following four word pairs are alike and thus form a group. Select the word pair that does NOT belong to that group. [S.S.C CHSL Tier II (02/11/2023)]

Correct Answer: (b) Theatre - movies
Solution:The relationship in each pair :
Restaurant - Chefs → Chefs work in a restaurant, providing a service (cooking food).
Theatre - Movies → Movies are shown in a theatre, but they do not work there; they are the product being presented.
Hospital - Doctors → Doctors work in a hospital, providing medical services.
School - Teachers → Teachers work in a school, providing educational services.
In three pairs (Restaurant - Chefs, Hospital - Doctors, and School - Teachers), the second item is a person or group providing a service at the place mentioned. However, in Theatre - Movies, movies are not people providing a service; they are the content being shown.
Hence, Theatre – Movies is the correct answer.

4. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL Tier II (02/11/2023)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: (a) 33 - 97
Solution:The pattern followed here is :

(1st number) × 3 = 2nd number
(25 - 75) → 25 × 3 = 75
(38 - 114) → 38 × 3 = 114
(41 - 123) → 41 × 3 = 123
But, (33 - 97) → 33 × 3 = 99 (Not 97)

Hence, 33 - 97 is the odd one.

5. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL Tier II (02/11/2023)]

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: (d) 33 - 152
Solution:The pattern followed here is :

(1st number) × 4 = 2nd number

(13 - 52) → 13 × 4 = 52
(25 - 100) → 25 × 4 = 100
(41 - 164) → 41 × 4 = 164
But, (33 - 132) → 33 × 4 = 132 (Not 152)

Hence, 33 -132 is the correct answer.
