### A car accident occurred on a busy street intersection killing two people and injuring three others. In order to nab the culprits, the police took the statements of all the witnesses present at that intersection, when the accident happened. Some of the witnesses were in a state of shock because of the horrific accident and were unable to correctly reproduce the details of the accident. The witnesses who were in a state of shock provided all incorrect details while the rest of the witnesses provide the correct information about the accident.  The following statements have been recorded by the police: Witness 1: Three people were killed in the accident by a red car that ran over them. Witness 2: The green car had a license plate with eight symbols on it, two of them being letters and the rest being digits. Witness 3: The car was blue in colour and was being driven by a young man with two people sitting in the backseat, one of them being a woman. Witness 4: Each of the last four digits on the license plate of the car was a power of the same number and they were in the ascending order. Witness 5: There was a blue car involved in the accident and a yellow car was right behind it. The blue car injured two people and rushed away from the spot. Witness 6: The car was a green Maruti with four people in it. The car hit five people injuring three of them. Witness 7: If numbers are assigned to the two letters on the license plate of the car with A being 1, B being 2 and so on, then the sum of the two letters on the license plate was equal to the sum of the last four digits. The letters were from A-l with the letter with the lower value coming first. The last four digits were in the ascending order.      Q. Among the last four digits on the license plate, what was the difference between the last digit and the first digit?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 3

Solution: From the statements made by witnesses 2, 4 and 7, it is known that the last four digits on the license plate were four powers of the same number in ascending order.
The only way this can happen is if all four digits are powers of 2.
The only powers of 2 that are single digit numbers in ascending order are 2°, 21, 22 and 23 i.e. 1,2, 4 and 8.
The digits are 1,2, 4 and 8 from left to right.
So, the required difference = 8 - 1 = 7 Hence, option 4.

Witness 4: Each of the last four digits on the license plate of the car was a power of the same number and they were in the ascending order.
Witness 5: There was a blue car involved in the accident and a yellow car was right behind it. The blue car injured two people and rushed away from the spot.
Witness 6: The car was a green Maruti with four people in it. The car hit five people injuring three of them.
Witness 7: If numbers are assigned to the two letters on the license plate of the car with A being 1, B being 2 and so on, then the sum of the two letters on the license plate was equal to the sum of the last four digits. The letters were from A-l with the letter with the lower value coming first. The last four digits were in the ascending order.

Q. Which of the following could have been the first letter in the license plate?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 4

Solution: Consider the solution to the previous question.Thus, the last four numbers on the license plate are 1, 2, 4 and 8.The sum of the last four digits is 15.The possible numeric value of the first 2 letters is (7, 8) or (6, 9)The letters corresponding to these numbers are (G, H) for (7, 8) and (F, I) for (6, 9) The only possibilities for the first letter are G or F since the letters are also arranged with the letter with lower value coming first.Thus, G could have been the first letter in the license plate. Hence, option 1.

CRPF Head Constable Mock Test - 6 - Question 21

Directions: Study the following information carefully and answer the questions given beside:
Eight persons- A, B, C, D, P, Q, R and S are sitting in a row in which some of them are facing north while some of them are facing south. Only 3 persons sit to the left of R. 3 persons sit between R and Q. B is 2nd to the left of Q. More than 2 people’s sits between B and S, D is 2nd to the left of S. Neighbours of R are facing south. Neighbours of P face the same direction. C is 2nd to the right of A. A and P face opposite directions and similarly B and Q face opposite directions too.

Q. How many person(s) sits to left of P?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 21

Following the final solution we can say that only 1 person sits to left of P.
Hence, the correct answer is option A

Common Explanation:
Reference:
Only 3 persons sit to the left of R.
3 persons sit between R and Q.
Inference:
As we don’t know that in which direction exactly R is facing. So, we can say that there possible scenarios in which we can use the above information correctly.
Case 1:
R faces north.

Case 2:
R faces south.

Reference:
B is 2nd to the left of Q.
Neighbours of R face the south.
B and Q face in opposite direction.
Inference:
We can use the above information in both of the cases accordingly as shown in the figures:

Reference:
More than 2 people’s sits between B and S.
D is 2nd to the left of S.
Inference:
After studying the first information we can say that either 3 or 4 persons are sitting between B and S. and with the second hint we can place D according to S in the row and we can say that there are exactly 4 persons are sitting between B and S.

Reference:
Neighbours of P face the same direction.
A and P faces in opposite direction.
C is 2nd to the right of A.
Inference:
With the first hint we can say that our case 2 is an invalid case as we cannot place P with both of its neighbour facing the same direction.
And after placing P in case 1 we can fix the position of A and C easily and can complete the puzzle.

CRPF Head Constable Mock Test - 6 - Question 22

DEER = 12215 and HIGH = 5654, how will you code HEEL?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 22

To solve the coding pattern, let's analyze the given codes for DEER and HIGH:

• DEER = 12215
• HIGH = 5654

We'll try to understand the pattern by matching each letter with its corresponding number.

For DEER:

• D -> 1
• E -> 2
• E -> 2
• R -> 5

For HIGH:

• H -> 5
• I -> 6
• G -> 5
• H -> 4

Let's try to find the pattern or rule:

1. D, E, R in DEER:

• D = 1
• E = 2
• R = 5
2. H, I, G, H in HIGH:

• H = 5 (H = 5 for HIGH, but H = 5 and 4 in DEER and HIGH respectively)
• I = 6
• G = 5
• H = 4

Now, let's find the code for HEEL:

• H -> 5 (from HIGH)
• E -> 2 (from DEER)
• E -> 2 (from DEER)
• L -> We need to determine L's code

Since L hasn't appeared yet, we need to figure out its code. Based on patterns, if the trend is alphabetical positioning, L could potentially be coded uniquely. Let's explore the pattern in numbers:

• H = 5
• E = 2
• E = 2
• L = ?

Considering possible consistency in coding and based on given options, the most logical way might use the remaining structure within the problem’s predefined context for HEEL = 5229.

So, the most likely answer should be:

4. 5229

CRPF Head Constable Mock Test - 6 - Question 23

If ZIP = 198 and ZAP = 246, then how will you code VIP?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 23

Taking Z = 2, Y = 3,……,N = 14,……..B= 26, A = 27 we have :
ZIP = (Z + I + P) × 6 = (2 + 19 + 12) × 6 = 33 × 6 = 198.
So, VIP = (V + I + P) × 6 = (6 + 19 + 12) × 6 = 37 × 6 = 222.

Twenty workers can finish a piece of work in 30 days. After how many days should 5 workers leave the job so that the work is completed in 35 days?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 31

Total man days required = 600 man days. If 5 workers leave the job after ‘n’ days, the total work
would be done in 35 days. We have to find the value of ‘n’ to satisfy:
20 × n + (35 – n) × 15 = 600.
Solving for n, we get
20n – 15n + 35 × 15 = 600
5n = 75
n = 15.

Of all the students in a certain dormitory, half are first-year students and the rest are second-year students. If 4/5 of the first-year students have not declared a major and the fraction of second-year students who have declared a major is 3 times the fraction of the first-year students who have declared a major, then what fraction of all the students in the dormitory are second-year students who have not declared a major?

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 40

Suppose total number of students in a certain dormitory = y
Then, total number of first-year students = y/2
Total number of first-year students who have not declared a major = (2/5)y
So, fraction of first-year students who have declared a major = (1/10)y
Total number of fraction of second-year students who have declared a major = (3/10)y
Total number of fraction of second-year students who have not declared a major = (1/5)y
Then, required fraction = (1/5)

CRPF Head Constable Mock Test - 6 - Question 62

Recently discovered gravitational lensing around certain proximate stars stronglysuggests that the nine planets of our solar system are a common phenomenonin the universe rather than developing incidentally from a unique galactic phenomenon several billion years ago.

Detailed Solution for CRPF Head Constable Mock Test - 6 - Question 62

The first thing you should consider here is whether to use rather or instead. Instead does not have an element of choice in it, merely an element of replacement. You would say, for example: I went instead of Jack. You would also say: He is a weak man rather than a timid man. Because this is not a case of replacement, you need the word ‘rather’. That leaves us with choices A, B and C as possible answers. A correct comparison is required. The planets are a ‘phenomenon... rather then a type’. You are correctly comparing two nouns so A can be eliminated. ‘Incidental of’ is an incorrect structure. ‘Incidental to’ is correct. Therefore only B is eliminates all these errors and is the correct answer.
