Punjab Police Head Constable Paper 2 Mock Test - 9 - Punjab Police Constable MCQ

The numeric value of the letters (considering A to be 1 and Z to be 26) is added and simplified to obtain a single digit.

For RAM, the numeric value of R, A and M is 18, 1 and 13 respectively. Their sum is 32, Now 32 is further simplified to obtain a single digit by adding 3 and 2, which gives us 5 as the final value.
Similarly for GUI, the numeric value of G,U and I is 7, 21 and 9 respectively. Their sum is 37, which is simplified as 3 + 7 = 10 => 1 + 0 = 1.
Similar process will be done to obtain the code for SAP, the numeric value of S, A and P is 19, 1 and 16 respectively. Their sum is 36, which is simplified as 3 + 6 = 9.
So, the code for SAP is 9.
Hence option (B) is correct.

Given:

Five years ago, father's age was 5 times that of his son

After 3 years father will be 3 times as old as his son

Calculation:

Let the present age of son be x years 

Present age of father be y years 

According to the question,

Five years ago, father's age was 5 times that of his son

(y - 5) = 5 (x - 5)

⇒ y - 5 = 5x - 25 

⇒ y - 5x + 20 = 0     ---- (i)

After 3 years father will be 3 times as old as his son

(y + 3) = 3(x + 3)

⇒ y + 3 = 3x + 9

⇒ y - 3x - 6 = 0      ---- (ii)

Solving equation (i) and (ii) we get,

x = 13

∴ Present age of son is 13 years

When the digits of the number '6379452' are arranged in ascending order,
then rearrangement will be 2 3 4 5 6 7 9

Now, fourth digit from the left = 5

Second digit from the right = 7

Sum of fourth and second digit = 5 + 7 = 12

T is the daughter of R.

13.24 + 24.35 + 35.46 – 46.57 = 2 × ?

⇒ 73.05 – 46.57 = 2 × ?

⇒ 26.48 = 2 × ?

⇒ 26.48/2 = ?

∴ 13.24 = ?

From the common explanation, we can say that R sits 3rd to the right of the one who sits immediate right of M. 
Hence, Option D is correct.
Final Arrangement:

Common Explanation:
References:
Only two boys sit to the left of J.
Eight boys sit between R and J.
Only three boys sit between R and M.
Inferences:
From the above references, we get two different cases:

References:
P sits fourth to the right of R.
O sits third to the left of M.
Inferences:
So, from this case 2 will be eliminated as P sits fourth to the right of R.

References:
Only three boys sit between O and H.
T sits third to the right of M.
V sits fourth to the right of O.
More than 12 boys sit between P and H.
More than seven boys sit between P and J.
Inferences:
From the above reference, we get the final arrangement:

Following the common explanation, we get “C is the immediate neighbor of X”.
Hence, option D is correct.
Final Arrangement:

Common Explanation:
References:
1. Two people are sitting between A and Z.
2. C sits fourth to the right of Z.
3. The number of people sitting to the right of A is the same as the number of people sitting to the left of Z.
4. The number of people sitting between A and C is the same as the number of people sitting between X and C.
5. X is an immediate neighbour of D, who sits on one of the ends.
6. The number of people sitting between D and C is the same as the number of people sitting between C and Y.
7. At most 25 people are sitting in a row.
Inferences:
From reference 1, we get two possible cases.
From reference 7, case2 was eliminated.
Hence, Case 1 is the final arrangement.

The logic follows here : 
1. Sukhoi Su-30MKI is a Fighter Jet.
2. INS Vikrant is different from these two, it is an Aircraft Carrier.

The least possible Venn diagram for the given set of words is :

Hence, the correct answer is "Option (4)".

The sentence is in active voice with past continuous tense in it. When it is converted into passive voice, it still remains in past continuous tense but with a little variance due to its grammatical rule. In the sentence ‘was driving the car’ gets converted into ‘was being driven’ in case of passive voice.
Passive voice is given as :-
The car was being driven by him so fast that it skidded on the snowy road.
Hence , option D will be correct answer .

The given sentence is in the active voice: "I expect you to complete this work before sunset."

The correct transformation of this sentence into the passive voice is: "You are expected to complete this work before sunset."

Therefore, the correct answer is option B: "You are expected to complete this work before sunset."

The given sentence is of present perfect tense and it is in active form.

The structures for active/passive voices are:

Active: Subject + has/have + verb (IIIrd form) + object...

Passive: Object + has/have + been + verb (IIIrd form) + by + subject...

The active voice statement is in present perfect tense, thus the passive voice statement has to be in present perfect tense itself.

Out of the available options, only option (d) satisfies this criterion and thus, is the correct response.

The given idiom is underlined in the heat of the moment is used to imply that something has been done without understanding the consequences and such things are normally done for being overwhelmed by the things taking place at the moment, around a person that actually snatches away the power of a person to think rationally and logically. Among the given options we can see that option D gives us the correct meaning of the idiom as underlined.

This makes option D the correct choice among the given options.

Let us first learn the meanings of the given words:

Span (verb): extend across.

Extend (verb): cause to cover a wider area or make larger.

Vary (verb): differ in size, amount, degree, or nature from something else of the same general class.

Range (verb): extend between specified limits.

The idea here is to express that there was a huge range of reasons why the protests in China had started. Grammatically only a verb in ‘-ing’ form will fit the blank, this eliminates ‘span’, ‘extended’ and ‘vary’. Now, between ‘scoping’ and ‘ranging’, ‘ranging’ is a better option to be placed before ‘from’.

Hence, option d is correct.
