Indian Army Agniveer Mock Test - 5 - CDS MCQ

Let ‘x’ be the increase in the average 

For ‘x’ to be a whole number 72 (= 9 × 8) should be divisible by (n + 8) 
From the choices it can be said that 36 and 72 are two such factors. But 72 does not lie within the range. 
∴ number of students in class are 36.

26 + (34 * 43) – 96 + 69 = 1461

So Option B is correct

54679 + 5982 + 32614 = 93275
312 * 69 = 21528
93275 – 21528 = 71747

So Option B is correct

original number – 10x + y
(10x + y) – (10y + x) = 27
9(x – y) = 27
x – y = 3
All the given options not follow the condition.

LCM*HCF = a*b
840*84 = 168*b, b = 420

Answer – b) losses 4% Explanation : let cost price = 100 so, marked price = 120 now discount of 20% is given, so sp = 120*80/100 = 96 so % loss = (4/100)*100 = 4 percent

Let (a + b) = 6k, (b + c) = 7k and (c + a) = 8k.
Then, 2 (a + b + c) = 21k
2 × 14 = 21k
k = 28/21 = 4/3
(a + b) = (6 × 4/3) = 8
c = (a + b + c) - (a + b) = (14 - 8) = 6

Number of notes of Rs. 20 = 12
Number of notes of Rs. 10 = 12/4 = 3
Number of notes of Re. 1 = 7 × 3 = 21
Total amount = 12 × 20 + 3 × 10 + 1 × 21 = 240 + 30 + 21 = Rs. 291

Total cost = 360 × 0.78 + 14 + 13 + 5 = Rs. 312.80
He needs to sell 353 eggs for 312.8 + 70 = Rs. 382.8.
Thus, price of one egg = Rs. 1.08

Diameter of the hemispherical cup = 14 m
Therefore, radius of the hemispherical cup = 7 m
We know that,
Volume of the hemisphere 
Volume of sphere 
Let r be the radius of a stone.
According to the question,
350 × volume of stone = volume of hemispherical cup

700r³ = (7)³
r³ = 0.49

Therefore, radius is 0.79 m.

Radius of cylindrical pipe (r) = 5/2 meters
Flow rate = 20 m/min
Diameter of conical vessel = 80 meters
Depth of the vessel (h) = 48 meters
According to the question,
Volume of the chemical flow through the pipe in one minute,

[here, h = 20 m]
= 125π m³
Volume of conical vessel,

= 25,600 m³
Therefore, time taken
 

In September 1932, Mahatma Gandhi began a fast unto death to protest British support of a new Indian Constitution that would separate the Indian electorate by caste. After just six days, the British accepted an alternate proposal and he was able to break the fast.

The correct answer would be Option B. 
The Rowlatt Act aimed at imprisonment without trial and summary procedures for trial. Despite much opposition, the Rowlatt Act was passed in March 1919. The purpose of the act was to curb the growing nationalist upsurge in the country. Mahatma Gandhi, among other Indian leaders, was extremely critical of the Act and argued that not everyone should be punished in response to isolated political crimes.
 

The Aravalli Range, literally meaning 'line of peaks', is a range of mountains in western India and eastern Pakistan running approximately 800 km from north-west to southwest across Indian states of Rajasthan, Haryana, and Gujarat and Pakistani provinces of Punjab and Sindh. It is one of the world's oldest Mountain ranges. It dates back to pre-Indian sub-continental collision with the mainland Eurasian Plate.

International Malala Day is observed every year on July 12 to celebrate the life and legacy of Pakistani education activist Malala Yousafzai. The passage provides a historical context, stating that the United Nations first celebrated this day on July 12, 2013, a year after Malala was shot by a Taliban gunman for advocating for girls' education. The passage further explains the objective of the day, which is to urge world leaders to ensure free and mandatory education for girls, emphasizing education as a fundamental right for everyone.

1. The energy possessed by a body by its motion is called kinetic energy.
2. K.E = ½ × mv² where, m = mass, v = velocity, K.E = kinetic energy.
3. Potential Energy is possessed by its position or configuration.
4. When a body falls from an aeroplane its velocity increases, so it's kinetic energy increases (K.E = ½ × mv²).
   Correct option is C. Kinetic Energy

For fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting. Microwave technology is extensively used for point-to-point telecommunications (i.e., non broadcast uses). 

Sudden and great fluctuations of the barometer at any time of the year indicate unsettled weather for several days, perhaps a fortnight. If the barometer falls two or threetenths of an inch in four hours, one can expect a gale of wind. If the surface of the mercury in the cistern of the barometer vibrates upon the approach of a storm, the gale can be expected to be severe.

The main source of Naphthalene is coal-tar. Naphthalene is derived from a kind of naphtha which is a broad term encompassing any volatile, namable liquid hydrocarbon mixture, including coaltar. 

A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Materials presently used for photovoltaic solar cells include mono-crystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper iridium selenide/sulfide.

Quartz is made up of a continuous framework of SiO₄ silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO₂. Tridymite and cristobalite are hightemperature polymorphs of SiO₂ that occur in high-silica volcanic rocks. Coesite is a denser polymorph of quartz found in some meteorite impact sites and in metamorphic rocks.

More than 90% of world production of urea is destined for use as a nitrogen-release fertilizer. Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use.

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily a compact energy store. The mean normal blood glucose level in humans is about 4 mM (4 mmolit, or 72 mg/dL, i.e. milligrams/ deciliter); however, this level fluctuates throughout the day. 

Mumps (epidemic parotitis) is a viral disease of the human species, caused by the mumps virus. Before the development of vaccination and the introduction of a vaccine, it was a common childhood disease worldwide. It is still a significant threat to health in the third world, and outbreaks still occur sporadically in developed countries. Painful swelling of the salivary glands (classically the parotid gland) is the most typical presentation.

The near point for a person with hypermetropia (long-sightedness) is the closest point at which they can see objects clearly. In such a condition:

• The near point is typically greater than 25 cm.
• This means they have difficulty focusing on objects that are closer than this distance.

Corrective lenses can help adjust their focus, allowing them to see nearby objects more clearly.

Kaushal and Beena are sitting at the extreme ends of line.
Option C, is hence the correct answer.

There are only three persons between Jaya and Ajit.
Inference:

Reference:
Dimple is not an immediate neighbour of either Kaushal or Beena.
Inference:

Final image:

Clearly, the solution to the problem is not to close down the Municipal and Zila Parishad-run schools but to strive to improve the standard of education of these schools. So, only I follows while II does not.
