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)

12 + 19 + 23 + 7 + x + 9 + 26 + 13 = 16 × 8
109 + x = 128
x = 128 – 109 = 19
Hence, Option D is correct.

Hence, Option A is correct.

So the answer = 100% – 96.875% = 3.125%
Hence, Option A is correct.

Let the number be x.
According to the question,

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.

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).

The word that can be suffixed to form new words is ‘ure’

Fail + ure = Failure

Press + ure = Pressure

Depart + ure = Departure

Advent + ure = Adventure

Hence, the correct answer is "ure".

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.

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.

The above information can be summarized below diagram,

Therefore, the code for “was” will be “3”. 

Hence, option 4 is the correct answer.

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

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see Y and Z pairs of friends are good, both in English and Science

Hence, the correct answer is "Y and Z".

Thus, the code for REMAIN is 8@7$%6.
Hence, option D is correct.

After rearrangement, we get the following arrangement:

So, E is sitting 3rd to the left of D after rearrangement.
Hence, Option C is correct.
Final Arrangement:

Common explanation:
References:
Six person A, B, C, D, E and F sit around a triangular table.
One person sits at each corner of the table facing away from the centre while one person sits at the middle of each edge facing toward the centre.
Inferences:
So, we need to arrange as follows to accommodate the information as stated in the question,

References:
Three persons sit between C and D, who is not facing the centre.
Inferences:
From the above reference, we get two different cases:
Case 1:

Case 2:

References:
F sits third to the left of C.
A sits second to the left of E.
A is not an immediate neighbour of D.
Inferences:
So, from this case 2 will be eliminated as A is not an immediate neighbour of D.
Case 1:

Case 2: (Eliminated)

Hence, Case 1 is the final arrangement.

The correct order will be:
The national unity of a free people → depends upon a sufficiently even balance of political power (R)→ against a revolutionary opposition that is irreconcilably opposed to it (S)→ to make it impracticable (P)→ for there to be an arbitrary administration. (Q)

Use structure “subject + auxiliary + past participle + by + object”
As per the given above sentence is given in Active Voice.
I was hurt deeply by his comment.
Thus , required answer will be option A .

The sentence is in active voice and to convert it in passive voice the predicate of the sentence becomes the subject.
Use structure “auxiliary + past participle”
As per the given above sentence is given in Passive Voice.
The dog was taken for a walk by her.
Hence , required answer will be option C .

Porous means (of a rock or other material) having minute interstices through which liquid or air may pass

Synonyms: permeable, penetrable, pervious
For instance, the new moonlet might be porous, like an orbiting icy rubble pile
Very high capacity supercapacitors use a porous carbon-based electrode material

After looking at the given parts  P, Q, R, and S, it can be concluded that the correct order will be:  

When he → heard the hue and cry at midnight → he was nervous and → did not know → what to do. 

So, correct order is RQPS.

Explanation:

• Understanding the context: The sentence is talking about birds being found all over the world and some birds restricting themselves to certain areas. It indicates that not all birds are found everywhere.


• Exploring the options:
  
  
  
  • A: All - This option implies that all birds are found everywhere, which contradicts the context of the sentence.
  
  
  • B: Most - While most birds may be found in various habitats, it does not account for the specific habitats mentioned in the sentence.
  
  
  • C: Some - This option correctly reflects the idea that only some birds are found in specific areas, aligning with the context.
  
  
  • D: More - This option does not provide a suitable replacement in the context of the sentence.
  
  
  • E: None of these - This option is not relevant as option C fits the context.
  
  
  
  


• Conclusion: The most appropriate word for Blank No. 35 is "Some" as it accurately represents that only a portion of birds are found in specific areas.

Safety in numbers (Idiom): being in a group offers security and protection.
Sporting chance (Idiom): a reasonable chance of winning or succeeding.
Square deal (Idiom): an instance of being treated fairly.
Standing joke (Idiom): something that regularly causes amusement or provokes ridicule.
It is obvious that ‘safety in numbers’ makes perfect sense in the given blank.
Hence, the correct answer is option A. 

The sentence "We must respect the elders" in the Active Voice can be transformed into the Passive Voice as:

A. The elders must be respected.

This option accurately conveys the original meaning of the sentence in the Passive Voice.

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.
