HP Patwari Mock Test - 6 - HP Patwari MCQ

12 couples = 24 people

And every couple has at least one child. So, Minimum 12 children

∴ Total 24 + 12 = 36 People

Given:

Sum of radii of two sphere = 10 cm

Sum of their volume = 880 cm³

Volume of a sphere = (4/3) x π x r³ 

Let r₁ and r₂ be the radii of two different sphere.

From question,

⇒ r₁ + r₂ = 10 ...(i) 

Now,

⇒ (r₁ + r₁)³ = (10)³

⇒(r₁ + r₁)³ = 1000 ....(ii)

⇒ 1000 = 210 + 3r₁r₂ (10)

⇒ 1000 - 210 = 30r₁r₂

⇒ 790 = 30 r₁r₂

⇒ r₁r₂ = 790/30

⇒ r₁r₂ = 79/3

Product of their radii = 79/3.

Given,

The ratio of men, women, and children = 9 : 8 : 3

Suppose, Men = 90, Women = 80, Children = 30

Total population = 200

Now, the number of literate men .....(i)

The number of literate women .....(ii)

The number of literate children .....(iii)

Total literate = 155

Total illiterate 200 - 155 = 45

So, illiteracy rate = (45/200) x 100

⇒ 22(1/2)%

Let the original speed of the car is x km/hr.

Then, time taken in moving 840 km = (840/x) hr

If speed is going 10 km/hr more = x + 10

Then, time taken in moving 840 km hr

⇒ 840(x + 10) - 840x = 2x(x + 10)

⇒ 2x² + 20x - 8400 = 0

⇒ x² + 70x - 60x - 4200 = 0

⇒ (x + 70)(x - 60) = 0

⇒ x = 60 or x = -70

If x = -70 is not true because the speed is not negetive.

So, speed is 60 km/hr.

Let the number of small spheres be n.

We know that,

Volume of sphere =

According to the question,

⇒ n = 125/8 = 15 (Approx)

Thus, 15 such spheres can be made.

Given:

A train of length 240 m crosses a pole in 16 seconds

The same train crosses a platform in 42 seconds

Concept:

Speed = Distance/Time

When a train crosses a pole then it covers its length

When a train crosses a platform then it covers its length + length of the platform

Calculation:

According to the question,

Speed of the train = 240/16 = 15 m/second

Now, in 42 sec the train will cover 42 x 15 = 630 m

So, the length of the platform is 630 - 240 = 390 m

∴ The length (in m) of the platform is 390.

Given that,

(x - 5)(x - 1) + (y - 7)(y - 4) = 0

⇒ x² - 6x + 5 + y² - 11y + 28 = 0

⇒ x² + y² - 6x - 11y + 33 = 0

Comparing with standard form of circle x² + y² + 2gx + 2fy + c = 0,

2gx = -6x

2fy = -11y

c = -33

⇒ g = -3

⇒ f = (-11)/2

Center = (-g, f)

Radius

= 5/2

The correct sequence is:

1. Write - we use a pencil to write (b. pencil)
2. Cut - we cut vegetables (c. vegetables)
3. Sweep - we need a broom to sweep (d. broom)
4. Read - we read books (e. book)
5. Fly - we fly in aeroplanes (a. aeroplane)

The most appropriate meaning of the given idiom 'By leaps and bounds' is 'very fast'.

By leaps and bounds: very quickly

Example: Her health is improving by leaps and bounds.

A flock of seagulls flew over the ship screeching raucously.

It is appropriate to use Collective Noun 'flock' in the blank space of the sentence.

The indirect speech of the given sentence is '​She told Mohit that Rohit had arrived on Sunday.​'

When the reporting speech is in Simple Past Tense then all the speech Changes to Past Perfect tense.

Arrived - Had arrived

Said to of the reporting verb changed into told.

Replace comma (,) and inverted commas (" ") with the conjunction 'that'.

The third person(Rohit) of the reporting speech remains unchanged.

​So, the final sentence is: 'She told Mohit that Rohit had arrived on Sunday.​​

Let's look at the meaning of the given word and the correct answer.

Authentic (adjective): If something is authentic, it is real, true, or what people say it is.

​Example: He was there and saw what happened, so he is the only authentic account.

Fake (noun): an object that is made to look real or valuable in order to deceive people.

Example: Experts revealed that the painting was a fake.

Part (A) has the grammatically incorrect part. These two tenses are used to talk about things that happened in the past. However, we use past perfect to talk about something that happened before another action in the past, which is usually expressed by the past simple. The cake cutting ceremony happened first in the order; therefore, we will use past perfect tense here. Replace “has” with “had” to make the sentence grammatically correct.

The correct usage would be 'more brave' or 'braver'.

The use of 'braver' after 'more' is redundant.

So, we do not use 'more' before a comparative form.

So, the correct sentence is:

"Nikhil is more brave than Sushant who is afraid."

A possessive adjective is a word that indicates the possession of the noun to a person/group.

• These are: my, his, her, its, their, your, our.

Farming is most affected by climate.

The changing climate is have far-reaching impacts on agricultural production. Climate change affects farming in several ways, including through changes in average temperatures, rainfall, and climate (e.g. heat waves), changes in pests, changes in atmospheric carbon dioxide, and ground-level ozone concentrations. Many weeds, pests, and fungi thrive under warmer temperatures, wetter climates, and increased CO₂ levels and affect the agricultural crop.

The Himalayan princely state Praja Mandal established in 1939 AD.

The struggle for independence was at its peak all over India. In the hilly areas also, the light of independence was awakened through the 'Prajamandal Movement'. Praja Mandal was related to the farmers who fought against the princely rule in their own way. In 1939, the session of 'All India State People's Congress' was held in Ludhiana in which it was decided to create Praja Mandal in hill states and to give special attention to these areas. To run the movement in all the districts of India, the allied organization of Congress was also called upon to intensify the work of Prajamandals through the State Council and Pattabhi Sitaramayya was entrusted with this work.

A wide range of organisms belonging to bacteria, viruses, fungi, protozoans, helminths, etc. could cause diseases in man. Such disease-causing organisms are called pathogens

Salmonella typhi is a pathogenic bacterium that causes typhoid fever in human beings. Therefore, statement 1 is correct.

• These pathogens generally enter the small intestine through food and water contaminated with them and migrate to other organs through blood.
• Sustained high fever (39° to 40°C), weakness, stomach pain, constipation, headache, and loss of appetite are some of the common symptoms of this disease.
• Intestinal perforation and death may occur in severe cases. Typhoid fever could be confirmed by the Widal test.

Bacteria like Streptococcus pneumonia and Haemophilus influenza are responsible for the disease pneumonia in humans which infects the alveoli (air-filled sacs) of the lungs. Therefore, statement 2 is correct.

• As a result of the infection, the alveoli get filled with fluid leading to severe problems in respiration.
• The symptoms of pneumonia include fever, chills, cough, and headache.
• In severe cases, the lips and fingernails may turn grey to bluish in colour.
• A healthy person acquires the infection by inhaling the droplets/aerosols released by an infected person or even by sharing glasses and utensils with an infected person.
• Dysentery, plague, diphtheria, etc. are some of the other bacterial diseases in man.

Some of the human diseases are caused by protozoans too. Plasmodium, a tiny protozoan is responsible for this disease.

• Different species of Plasmodium (P. vivax, P. malaria, and P. falciparum) are responsible for different types of malaria. Therefore, statement 3 is correct.
• Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.

Contours are the most accurate method of representing relief features.

Contouring is an act of using contour lines when representing the relief of an area on the map. Contour lines are the lines drawn on the map connecting all points on the earth’s surface with equal elevations above a fixed datum line (usually the mean sea level).

They are numbered in either feet or meters, above sea level. Usually, these numbers represent the exact elevation of land above sea level for all points along that line. Contour lines never cross or intersect each other. The spacing or gap between the contour lines represents the degree of slope. Contour lines lie perpendicular to streams and rivers.
