Select the set in which the numbers are related in the same way as are the numbers of the given sets.

(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 /deleting /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.)

  4. DOption (d)

    (34, 60, 21) 

View answer & explanation

Correct answer

Answer: (c)C.

(32, 84, 11)

Why this answer is correct

The logic followed in the given sets is:

Logic: Middle number = (First number - Last number) × 4.

(29, 52, 16)

→ (29 - 16) × 4

→ 13 × 4

→ 52 

(35, 44, 24)

→ (35 - 24) × 4

→ 11 × 4

→ 44 

Now, let's apply this logic to the given options:

1) (28, 35, 15)

→ (28 - 15) × 4

→ 13 × 4

→ 52 ≠ 35. Incorrect.

2) (30, 66, 16)

→ (30 - 16) × 4

→ 14 × 4

→ 56 ≠ 66. Incorrect.

3) (32, 84, 11)

→ (32 - 11) × 4

→ 21 × 4

→ 84 = 84. This holds.

4) (34, 60, 21)

→ (34 - 21) × 4

→ 13 × 4

→ 52 ≠ 60. Incorrect.

Hence, the correct answer is "Option 3".

Question 125

MeaningSisterFatherWifeMother
of B

Given Expression: G & H # I % J @ K & L

G & H: G is the father of H.

This confirms G is male.

H # I: H is the sister of I.

This confirms H is female. G is the father of both H and I.

I % J: I is the mother of J.

This confirms I is female.

J @ K: J is the wife of K.

This confirms J is female and K is male.

K & L: K is the father of L.

    ×, ÷, +, -

  2. BOption (b)

    -, ×, ÷, +

  3. COption (c)

    +, -, ×, ÷ 

  4. DOption (d)

    ÷, -, +, × 

View answer & explanation

Correct answer

Answer: (a)A.

×, ÷, +, -

Why this answer is correct

BODMAS Rule:

The given equation is:

14 * 15 * 5 * 7 * 2 = 47

Let's check each option by replacing the * signs with the given operators to find the one that balances the equation.

1) ×, ÷, +, −

Equation: 14 × 15 ÷ 5 + 7 − 2 = 47

⇒ 210 ÷ 5 + 7 − 2 = 47

⇒ 42 + 7 − 2 = 47

⇒ 49 − 2 = 47

⇒ 47 = 47 (Correct)

2) −, ×, ÷, +

Equation: 14 − 15 × 5 ÷ 7 + 2 = 47

⇒ 14 − 75 ÷ 7 + 2 = 47

⇒ 14 − 10.71 + 2 = 47

⇒ 5.29 = 47 (Incorrect)

3) +, −, ×, ÷

Equation: 14 + 15 − 5 × 7 ÷ 2 = 47

⇒ 14 + 15 − 35 ÷ 2 = 47

⇒ 29 − 17.5 = 47

⇒ 11.5 = 47 (Incorrect)

4) ÷, −, +, ×

Equation: 14 ÷ 15 − 5 + 7 × 2 = 47

⇒ 0.93 − 5 + 14 = 47

⇒ 9.93 = 47 (Incorrect)

Hence, the correct set of signs is "Option 1".

Question 129

Delhi Police Driver 2022• General Intelligence

In a certain code language, 'FIG' is written as '9' and 'PEAR' is written as '12'.How will 'ALMOND' be written in that language?

  1. AOption (a)

    18

  2. BOption (b)

    22

  3. COption (c)

    16

  4. DOption (d)

    12

View answer & explanation

Correct answer

Answer: (a)A.

18

Why this answer is correct

Solution:

The logic is to multiply the number of letters in the word by 3.

For FIG:

Number of letters = 3

 3 × 3 = 9

For PEAR:

Number of letters = 4

4 × 3 = 12

Similarly, 

For ALMOND:

Number of letters = 6

6 × 3 = 18

Therefore, 'ALMOND' will be written as 18.

Hence, the correct answer is "Option 1".

Question 130

Delhi Police Driver 2022• General Intelligence

Based on the position in the English alphabetical order, three of the following letterclusters are alike in some manner and one is different. Select the odd letter-cluster.

  1. AOption (a)

    SUWY

  2. BOption (b)

    JMOP

  3. COption (c)

    NQST

  4. DOption (d)

    TWYZ

View answer & explanation

Correct answer

Answer: (a)A.

SUWY

Why this answer is correct

The letter-cluster that does not belong to the group is SUWY.

The logic followed here is that in each letter-cluster, the letters are placed with a decreasing difference of +3, +2, and +1.

Option (1): SUWY

                                   

Option (2): JMOP

 

                                 

Option (3): NQST
