Hence, the correct answer is "Option 2".

Question 132

Delhi Police Driver 2022• General Intelligence

If the given sheet is folded to form a cube, which of the following figures are possible? 

  1. AOption (a)

    Only A, C and D

  2. BOption (b)

    Only C and D

  3. COption (c)

    Only A and C

  4. DOption (d)

    Only B and C

View answer & explanation

Correct answer

Answer: (b)B.

Only C and D

Why this answer is correct

If the given sheet is folded to form a cube,

Opposite numbers:

3 ⇒ 1 

6 ⇒ 5

4 ⇒ 2

Lets check each figure and verify which is/are possible:

Figure A 

→ Can not be made, because 1 and 3 are the opposite faces,

Figure B 

 → Can not be made, because 6 and 5 are the opposite faces,

Figure C 

 → Can be made, because all the surfaces are adjacent faces,

Figure D 

 → Can be made, because all the surfaces are adjacent faces,

Thus, Only C and D are possible.

Hence, 'option 1' is the correct answer.

Question 133

Delhi Police Driver 2022• General Intelligence

The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair. 

  1. AOption (a)

     44 : 22

  2. BOption (b)

    16 : 8

  3. COption (c)

    32 : 16

  4. DOption (d)

    20 : 4

View answer & explanation

Correct answer

Answer: (d)D.

20 : 4

Why this answer is correct

The logic followed here is:

  1. 44 : 22 → 22 = 44 ÷ 2

  2. 16 : 8 → 8 = 16 ÷ 2

  3. 32 : 16 → 16 = 32 ÷ 2

Whereas,

4) 20 : 4 → 4 = 20 ÷ 5 (not ÷ 2)

So, 20 : 4 is the odd pair.

Hence, the correct answer is "Option 4".

Question 134

Delhi Police Driver 2022• General Intelligence

In a certain code language, ‘TEA’ is written as ‘78’, and ‘WATER’ is written as ‘335’. How will ‘MILK’ be written in that language?

  1. AOption (a)

    184

  2. BOption (b)

    188

  3. COption (c)

    172

  4. DOption (d)

    180

View answer & explanation

Correct answer

Answer: (d)D.

180

Why this answer is correct

Solution:

The logic is to multiply the sum of the positional values of the letters by the number of letters in the word.

For TEA: 78

Positional values: T(20), E(5), A(1)

Sum of values = 20 + 5 + 1 = 26

Number of letters = 3

 26 × 3 = 78 

For WATER: 335

Positional values: W(23), A(1), T(20), E(5), R(18)

Sum of values = 23 + 1 + 20 + 5 + 18 = 67

Number of letters = 5

 67 × 5 = 335 

Similarly, 

For MILK:

Positional values: M(13), I(9), L(12), K(11)

Sum of values = 13 + 9 + 12 + 11 = 45

Number of letters = 4

45 × 4 = 180

The code for 'MILK' is 180.

Hence, the correct answer is "Option 4".

Thus, the missing number in the series is 239.

Hence, the correct answer is "Option 4"

Question 137

Delhi Police Driver 2022• General Intelligence

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)

(225, 570, 361)

(121, 462, 441)

  1. AOption (a)

    (169, 143, 484)

  2. BOption (b)

    (81, 207, 529) 

  3. COption (c)

    (49, 70, 100) 

  4. DOption (d)

    (64, 272, 289)

View answer & explanation

Correct answer

Answer: (d)D.

(64, 272, 289)

Why this answer is correct

The logic followed in the given sets is:

Logic: Middle number = (Square root of the First number) × (Square root of the Last number) × 2.

(225, 570, 361)

→ (√225) × (√361) × 2

→ 15 × 19 × 2

→ 285 × 2

→ 570

(121, 462, 441)

→ (√121) × (√441) × 2

→ 11 × 21 × 2

→ 231 × 2

→ 462 

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

1) (169, 143, 484)

→ (√169) × (√484) × 2

→ 13 × 22 × 2

→ 572 ≠ 143. Incorrect.

2) (81, 207, 529)

→ (√81) × (√529) × 2

→ 9 × 23 × 2

→ 414 ≠ 207. Incorrect.

3) (49, 70, 100)

→ (√49) × (√100) × 2

→ 7 × 10 × 2

→ 140 ≠ 70. Incorrect.

4) (64, 272, 289)

→ (√64) × (√289) × 2

→ 8 × 17 × 2

→ 272 = 272. Correct

Hence, the correct answer is "Option 4".

Question 138

Delhi Police Driver 2022• General Intelligence

Three statements are given followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.

Statements:

Some strawberries are oranges.

Some strawberries are mangoes.

All mangoes are peaches.

Conclusions:

I. Some peaches are mangoes.

II. Some peaches are orange.

III. Some peaches are strawberries

  1. AOption (a)

    Only conclusions I and III follow

  2. BOption (b)

    Only conclusions II and III follow

  3. COption (c)

    Only conclusions I and II follow

  4. DOption (d)

    All conclusions follow

View answer & explanation

Correct answer

Answer: (a)A.

Only conclusions I and III follow

Why this answer is correct

The least possible venn diagram is given:

Conclusions:

I. Some peaches are mangoes - True(because all mangoes are peach it implies that some peach are mangoes).

II. Some peaches are orange - False(because, there is np direct relation is given between them so, it can be possible only).

III. Some peaches are strawberries - True(because some strawberries are mango ans all mangoes are peach it implies that some peach are strawberries).

Thus, Only conclusions I and III follow.

Hence, the correct answer is "Option 1".

Question 140

Delhi Police Driver 2022• General Intelligence

Which two signs and numbers need to be interchanged to make the following equation correct?

(7)2 – (56 ÷ 8) + (9 × 6) = 18

  1. AOption (a)

    8 and 6, ÷ and + 

  2. BOption (b)

    7 and 6, + and −

  3. COption (c)

    7 and 9, − and +

  4. DOption (d)

    7 and 8, − and + 

View answer & explanation

Correct answer

Answer: (d)D.

7 and 8, − and + 

Why this answer is correct

The given equation is:

(7)2 – (56 ÷ 8) + (9 × 6) = 18

Let's test the options to find the correct interchange that balances the equation.

Option 1: Interchange 8 and 6, and ÷ and +

The new equation becomes:

(7)2 – (56 + 6) ÷ (9 × 8)

= (7)2 – (56 + 6) ÷ (9 × 8)

= 49 – 62 ÷ 72

= 49 – 0.86

= 48.14 ≠ 18

This option is incorrect.

Option 2: Interchange 7 and 6, and + and –

The new equation becomes:

(6)2 + (56 ÷ 8) – (9 × 7) = 18

= (6)2 + (56 ÷ 8) – (9 × 7)

= 36 + 7 – 63

= 43 – 63

= −20 ≠ 18

This option is incorrect.

Option 3: Interchange 7 and 9, and – and +

The new equation becomes:

(9)2 + (56 ÷ 8) – (7 × 6) = 18

= (9)2 + (56 ÷ 8) – (7 × 6)

= 81 + 7 – 42

= 88 – 42

= 46 ≠ 18

This option is incorrect.

Option 4: Interchange 7 and 8, and – and +

The new equation becomes:

(8)2 + (56 ÷ 7) − (9 × 6) = 18

= (8)2 + (56 ÷ 7) − (9 × 6)

= 64 + 8 − 54

= 72 − 54

= 18

Since 18 = 18, the equation is correct.

Hence, the correct answer is "Option 4".
