An aeroplane when 750 m high passes vertically above another aeroplane at an instant when their angles of elevation at same observing point are 45° and 30&de; respectively. Approximately, how many meters higher is the one than the other?

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 6


Let C and D be the position of the aeroplanes.
Given that CB = 900 m,∠CAB = 60°,∠DAB = 45°
From the right △ ABC,
Tan45 = CB/AB => CB = AB
From the right △ ADB,
Tan30 = DB/AB => DB = ABtan30 = CBx(1/√3) = 750/√3
CB = CD + DB
=> Required height CD = CB - DB = 750 - 750/√3 = 250(3 - √3)

Hence, Option D is correct.

Delhi Police Head Constable Mock Test - 7 - Question 8

According to the question,

Delhi Police Head Constable Mock Test - 7 - Question 11

Sarthak can destroy a work in 90 days and Deepak can destroy the same work in 60 days. In how many days can both of them together destroy the work?

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 11

Let total work be LCM of (90, 60) = 180 unit
Ratio of number of days by Sarthak and Deepak = 90 : 60 = 3 : 2
Ratio of efficiency of Sarthak and Deepak = 2 : 3
Total unit in one day = 2 + 3 = 5 unit
Number of days taken = 180/5 = 36 days 
Hence, Option B is correct.

Delhi Police Head Constable Mock Test - 7 - Question 12

The ratio of 1 hour to 300 seconds is:

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 12

The ratio of 1 hour to 300 seconds is:

  • To compare time, we should convert both times to the same unit. Let's convert 1 hour to seconds (since 1 hour = 3600 seconds).
  • 1 hour = 1 × 3600 seconds = 3600 seconds
  • Now we have 3600 seconds to 300 seconds. The ratio is  3600 : 300.
  • To simplify, divide both by their greatest common divisor, which is 300.
  • So, the ratio is 12 : 1, which corresponds to option (b).
Delhi Police Head Constable Mock Test - 7 - Question 13

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 13

Delhi Police Head Constable Mock Test - 7 - Question 14

Amit is twice as good as Ramit. Working together they can complete the work in 28 days. In how many days can Ramit alone can do the same whole work?

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 14

Given:

Efficiency of Amit = 2 × Efficiency of Ramit

Concept used:

Total work = Efficiency × Time period

Calculation:

The efficiency of Amit = 2

Efficiency of Ramit = 1

Total work = (2 + 1) × 28 = 3 × 28 = 84

Number of days Ramit takes to complete the whole work = 84/1 = 84

∴ The number of days in Ramit will complete the work is 84 days.

Delhi Police Head Constable Mock Test - 7 - Question 15
If x + 1/x = 25, find the value of x – 1/x.
Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 15

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p2 – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p2 – 4)

⇒ x – 1/x = √(252 – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

∴ value of x – 1/x is √621.
Delhi Police Head Constable Mock Test - 7 - Question 16

Delhi Police Head Constable Mock Test - 7 - Question 17
Five years ago, father's age was 5 times that of his son and after 3 years he will be 3 times as old as his son. Find the present age of son.
Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 17

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

Delhi Police Head Constable Mock Test - 7 - Question 30

A dot matrix printer
(i) prints an entire line at time
(ii) is a non-impact printer
(iii) allows multiple copies to be taken at a time
(iv) prints one character at a time 

Detailed Solution for Delhi Police Head Constable Mock Test - 7 - Question 30

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.
