The correct answer is less.

Key Points

• In normal conditions, the number of WBC in comparison to RBCs in the blood is less.
• The ratio of Red Blood Cells to White Blood Cells in the human body is 600:1.
• The primary function of red blood cells is to transport oxygen to body cells.
• White blood cells provide an immune system that defends the body against infectious diseases and foreign materials.
• The WBC is in the range of 4500–11000 per microliter of blood while RBC is in the range of 4.7–6.1 million cells per microliter.

Additional Information

• White blood cells, also called leukocytes make up approximately one percent by volume of the cells in the blood.
• They are primarily involved in the immune response to identify and target pathogens, such as invading bacteria, viruses, and other foreign organisms.
• White blood cells are formed continually; some only live for hours or days, but some live for years.
• Leukocytes are further classified into two subcategories:
• Granulocytes consist of neutrophils, eosinophils, and basophils.
• Agranulocytes consist of lymphocytes and monocytes.

Statement I: Pointing to the woman in the photograph, Harry said, “She is the daughter of my brother’s wife.”

Brother’s wife = Harry’s brother’s wife

Daughter of Harry’s sister-in-law = Niece of Harry

With this statement, we can determine that the woman in the photograph is the niece of Harry.

Statement II: Pointing to the woman in the photograph, Harry said, “She is the sister of Glenn’s father.”

We cannot determine any relationship between Harry and the woman with the statement above.

Hence, “Statement I alone is sufficient” is the correct answer.

Given:

Ratio between two numbers is 3 ∶ 5

LCM of these numbers is 240

Concept:

If the ratio of two numbers is given, and their LCM is known, then the numbers can be found by multiplying the ratio terms by the common factor obtained from LCM / (Product of the ratio terms).

Solution:

⇒ Common factor = LCM/(Product of ratio terms) = 240/(3 × 5) = 16

⇒ Numbers = 3 × 16 and 5 × 16 = 48 and 80

Hence, the two numbers are 48 and 80.

Thus, E visited on Thursday.

Hence, Thursday is the correct answer.

Shortcut Trick

Let initial Income = 100. Then Savings = 18 and Expenditure = 82.

Income increases by 41% (100 → 141). The savings amount remains the same (18).

Since Income = Expenditure + Savings, the entire increase in income must go to expenditure if savings is constant.

Increase in Expenditure = Income Increase = 41.

% Increase in Expenditure = (Increase ÷ Original Expenditure) × 100 = (41 ÷ 82) × 100 = 50%.

∴ The correct answer is 50%.

Alternate Method

Given:

Initial Savings = 18% of Income

Income Increase = 41%

Final Savings = Initial Savings (Amount)

Formula:

Income = Expenditure + Savings

Percentage Increase = (Change ÷ Original Value) × 100

⇒ Let original income = 100

⇒ Original Savings = 18

⇒ Original Expenditure = 100 − 18 = 82

⇒ New Income = 100 + 41% of 100 = 141

⇒ New Savings = 18 (amount remains constant)

⇒ New Expenditure = 141 − 18 = 123

⇒ Increase in Expenditure = 123 − 82 = 41

⇒ Percentage Increase = (41 ÷ 82) × 100

⇒ Percentage Increase = 1/2 × 100 = 50%

∴ The correct answer is 50%.

Additional Information

Income-Expenditure Components

Income is the sum of Expenditure and Savings. A change in any one component must be balanced by the others to satisfy the equation: ΔIncome = ΔExpenditure + ΔSavings.

Percentage Change Formula

To find the percentage increase or decrease, always use the initial value as the base: % Change = [(New Value − Old Value) ÷ Old Value] × 100.

Effect of Constant Component

If savings remains constant (ΔSavings = 0), then the absolute increase in income is exactly equal to the absolute increase in expenditure.

According to the given coding language,

So, H + O + P + E = 8 + 15 + 16 + 5 = 44 × 2 = 88

Similarly,

F + A + I + T + H = 6 + 1 + 9 + 20 + 8 = 44 × 2 = 88

Hence, 88 is the right answer.

Key Points

• It is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues, as well as removing carbon dioxide.
• During respiration, O2 is taken in and CO2 is released.
• The physical process that aids in this exchange is Diffusion.
• Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body.
• It occurs between the gas in the alveoli and the blood in the capillaries in the lungs.
• During the process of diffusion, the gases move from an area of high pressure to low pressure.

Logic is as follows:

Hence, option 4) is the correct answer.

Given:

Akash can complete the work in 40 days

Vikash can complete the work in 60 days

They work on alternate days, starting with Akash

Formula Used:

Work done by Akash in one day = 1/40

Work done by Vikash in one day = 1/60

Calculation:

Work done in 2 days (1 day Akash + 1 day Vikash) = 1/40 + 1/60

⇒ Work done in 2 days = 3/120 + 2/120

⇒ Work done in 2 days = 5/120

⇒ Work done in 2 days = 1/24

Total work = 1

Number of 2-day cycles needed = 1 / (1/24)

⇒ Number of 2-day cycles = 24

Each cycle consists of 2 days, so total days = 24 × 2 = 48 days

The correct answer is option (3).

The logic followed here is:

The difference between two consecutive numbers is equal.

Hence, "119" is the correct answer.

Alternate Method

The logic follows here is:

61 + (1)² + 1 = 61 + 2 = 63

63 + (2)² - 2  = 63 + 2 = 65

65 + (3)² + 3 = 65 + 12 = 77

77 + (4)² - 4 = 77 + 12 = 89

89 + (5)² + 5 = 89 + 30 = 119

119 + (6)² - 6 = 119 + 30 = 149

149 + (7)² + 7 = 149 + 56 = 205

Hence, the correct answer is "119".

If the reason for the strike is more important or concerns lives of people, then one could not worry about the damage caused to production. Thus, banning the strikes stating such reasons is an invalid idea.

Therefore, argument I is not strong.

Strike is a peaceful means to express one's dissatisfaction through refusal to work unless their demands are met. Therefore, banning this medium of expression would be detrimental to the right of expression of the workers. Also, some of them might be taking this step only when they run out of choices.

Taking away the only means of expression of such workers would leave them suppressed.

Thus, the reasons stated in argument II are strong enough to not ban strikes legally in India.

Hence, only argument II is strong.

Key Points

Explanation:

Ecosystem: All organisms such as plants, animals, microorganisms and human beings as well as the physical surroundings interact with each other and maintain a balance in nature.

All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem.

Food chain: A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat.

• A food chain shows how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposes such as fungi.
• They also show how animals depend on other organisms for food.

​

Only 10% of energy is transferred to higher levels from the previous one. So, the demand for food is more in higher levels. So, the food chain does not go for more than 3-4 tropic levels. This leads to more complex food forms known as a food web.

Primary (100%) → First level/ Primary (10%) → Second-level/ Secondary (1%) → Third level / Tertiary (0.1%).

Food web is a network of food chains where all the chains are naturally interconnected.

The flow of energy in a food chain is unidirectional, once it reaches the next tropic level it does not come back again.

• The materials like water, carbon (as carbon dioxide) and nitrogen (as minerals) are taken up by the plants from soil, air and water bodies, etc., and made into food. This food is then passed on to the animals like herbivores and carnivores in a food chain.
• After the death and decay of plants and animals, the materials like water, carbon and nitrogen present in their bodies are returned to soil, air and water, from where they were taken originally.
• These materials can then be reused for the growth of new plants. In this way, the same materials are used again and again, the materials are not lost from the environment. So, the flow of materials like water, carbon and nitrogen, etc., in the ecosystem is said to be cyclic. This is not so in the case of energy.

The correct answer is Iris.

Key Points

Organs related to anatomy of eye:

Hence Iris is related with the anatomy of the human eye.

Additional Information

• The patella is the largest sesamoid bone in the human body and is located anterior to knee joint.
• The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs.

Formula:

Total = [{(Left position) + (Right position)} - 1]

Where:

Left position = Position of A from the left end of the row.

Right position = Position of A from the right end of the row.

Given:

Atul rank from the left end = 17^th

Sachin rank from the right end = 15^th

Persons between Atul and Sachin = 5

Sachin rank from the right end = (17 + 6) = 23^rd

Here, the positions of Sachin from the right end and left end are 15^th and 23^rd respectively.

Total persons in the row = [{(Left position) + (Right position)} - 1]

Total = [{(15) + (23)} - 1] = 37

Total = 37

Here, the total number of persons in the row is 37.

Hence, the correct answer is "37".

Given:

A train running at 26.5 km/h takes 18 s to pass a platform.

Next, it takes 12 s to pass a man walking at 5 km/h in the opposite direction.

Concept used:

Relative speed is the sum of their individual speeds while two bodies are coming from the opposite direction.

1m/s = 18/5 km/h

Time × Speed = Distance

Calculation:

Total distance = 26.5 × 5/18 × 18 = 132.5 m

Hence, the relative speed of the train and the person

⇒ 26.5 + 5 = 31.5 km/hr

Length of train = 31.5 × 5/18 × 12

⇒ 105 m

Thus, the length of the platform = 132.5 - 105 = 27.5 m

∴ The length of the platform is 27.5 m.

The logic followed here is :-

1. Consonants - (6) is added to the position value.
2. Vowels - (6) is subtracted from the position value.
3. After addition/subtraction arranged in the reverse order.

The correct answer is Namami Devi Narmade

Key Points

• Namami Devi Narmada scheme has been launched by the Government of Madhya Pradesh for the conservation of the Narmada River.
• This initiative is aimed at rejuvenating the river by addressing pollution and promoting sustainable practices.
• The scheme includes activities like afforestation, sewage treatment, and public awareness campaigns.
• The Narmada River is one of the major rivers of central India and holds significant cultural and religious importance.
• The Madhya Pradesh government has taken various steps under this scheme to ensure the river's health and flow.

Additional Information

• The Narmada River, also known as the "Life Line of Madhya Pradesh," is the fifth longest river in India.
• It flows westwards over a length of approximately 1,312 km before draining into the Arabian Sea.
• The river basin is a crucial source of water for agriculture, drinking, and industrial purposes in the region.
• Efforts under the Namami Devi Narmada scheme are vital for maintaining the ecological balance and supporting the livelihoods dependent on the river.
• The scheme also emphasizes community participation and the involvement of local bodies in river conservation activities.

The correct answer is Mirage.

• To a distant observer, the light appears to be coming from somewhere below the ground.
• The observer naturally assumes that light is being reflected from the ground, say, by a pool of water near the tall object.
• Such inverted images of distant tall objects cause an optical illusion to the observer.
• **This phenomenon is called **a mirage.
• The optical illusion which occurs mainly in the desert during hot summer is based on the principle of TIR i.e total internal reflection.
• This type of mirage is especially common in hot deserts.

Additional Information

• Total Internal Reflection (TIR): When a ray of light goes from denser to the rarer medium it bends away from the normal and as the angle of incidence in denser medium increases, the angle of refraction in the rarer medium also increases and at a certain angle, angle of refraction becomes 90°, this angle of incidence is called critical angle (C).
• When the Angle of incidence exceeds the critical angle then the light ray comes back into the same medium after reflection from the interface. This phenomenon is called Total internal reflection (TIR).
• Conditions for TIR:

1. The ray must travel from denser medium to rarer medium.
2. The angle of incidence 'i' must be greater than the critical angle C.

The logic followed here is:-

So, 202 is the wrong number in the given series.

Hence, "option 1" is the correct answer.

Given:

Volume of hemisphere = 19404 cm³

Formula used:

The volume of Hemisphere = (2/3)πr³

The curved surface area of Hemisphere = 2πr²

Total surface area = 3πr² 

Concept used:

Total surface area = Curved surface area + Area of base

Calculation: 

Volume of hemisphere = 19404 cm3     

⇒ (2/3)πr³ = 19404

⇒ (2/3) × 22/7 × r3 = 19404

⇒ r3 = 19404 × (7/22) × 3/2

⇒ r3 = 9261

⇒ r = (9261)^1/3

⇒ r = 21

Now, Total surface area = 3πr2 

Total surface area = 3 × (22/7) × 21 × 21

∴ Total surface area is 4158 cm²

The journey is as represented in the diagram:

Diagram:

\(\sqrt {{{30}^2} + {{40}^2}} = \sqrt[2]{{2500}} = 50\)

The straight distance between Temple and the Gym = \(\sqrt {{{50}^2} + {{50}^2}} = \sqrt[2]{{5000}} = 70.71\)

Difference = 70.71 – 50 = 20.71 ≈ 20.7

Hence, the correct answer is 20.7 m

The correct answer is Only I.

Key Points

• Article 40 of the Indian constitution deals with the organisation of village panchayat.

​​Therefore only option one is correct.​

Explanation:

Rusting of iron:

Rusting is an oxidation reaction of iron. Iron reacts with oxygen and water to form rust which is iron oxide.

The process of rusting can be represented by the following equation as follows;

Iron (Fe) + Oxygen (O₂, from the air) + water (H₂O) → rust (iron oxide Fe₂O₃)

For rusting, the presence of both oxygen and water (or water vapour) is essential.

Opening of soda bottle: This is not an oxidation reaction. When a soda bottle is opened, the gas inside is released due to the decrease in pressure. There is no oxidation or reduction of any substance involved in this process.

Rancidity: Rancidity is a type of oxidation reaction that occurs in fats and oils. When fats and oils are exposed to air, the double bonds in the fatty acid molecules react with oxygen in the air to form peroxides, which further break down into aldehydes, ketones, and other compounds. These compounds have a rancid odor and taste.

Combustion: Combustion is a type of oxidation reaction in which a fuel reacts with oxygen to produce heat and light. Examples of combustion reactions include burning of wood, coal, and gasoline.

Therefore, the correct answer is Opening of soda bottle, which is not an oxidation reaction.

Given:

Side of square = 32 cm

Height of pyramid = 30 cm

Formula used:

Total surface area of pyramid = 1/2 × Base Perimeter x slant height + Base Area

Perimeter of square = 4 × Side

Area of square = (side)² 

Calculation:

Side of square (a) = 32 cm

Perimeter of square = 4 x 32 = 128

Area of square = (32)² = 1,024 

In the figure,

⇒ OR = 1/2 x side of square

⇒ 1/2 x 32 = 16 cm

⇒ Height (h) = OP = 30 cm

In △POR

⇒ (PR)² = (OR)² + (OP)²

⇒ (PR)² = (16)² + (30)²

⇒ (PR) = \(\sqrt{256 + 900}\)

⇒ PR = 34

Hence slant height(l) = PR = 34 cm

Now,

Total Surface Area of Pyramid = 1/2 x 128 x 34 + 1024

⇒ 3200 cm² 

∴ Total Surface Area of pyramid is 3200 cm².

Given

A batsman in his 12^th inning makes a score of 63 runs and there by increase his average score by 2

Concept used

Average = Sum of the observation/Total observation

Calculation

Let the total number of runs in 11 innings be "x".

the average number of runs in 11 innings is x/11

Let the total number of runs in 12 innings after scoring 63 runs in 12^th innings be x + 63.

Average number of runs in 12^th innings is = (x + 63)/12

⇒ (x + 63)/12 = x/11 + 2

⇒ (x + 63)/12 = (x + 22)/11

⇒ 11(x + 63) = 12(x + 22)

⇒ 11x + 693 = 12x + 264

⇒ 693 - 264 = 12x - 11x

⇒ 429 = x

Average of his score after 12 innings

⇒ (x + 63)/12

⇒ (429 + 63)/12

⇒ 41

∴ His average after the 12^th innings is 41.

Alternate Method

A batsman in his 12^th inning makes a score of 63 runs

His average increases by 2 runs

Increased runs = 11 × 2

Increased runs = 22 runs

His average after 12 innings 

⇒ 63 - 22

⇒ 41

The logic followed here is:

Logic: (1^st number + 3^rd number) ÷ 2 = 2^nd number.

Now,

For (32, 39, 46)

→ (32 + 46) ÷ 2

→ 78 ÷ 2 = 39.

For (54, 51, 48)

→ (54 + 48) ÷ 2

→ 102 ÷ 2 = 51.

Similarly, for (48, 30, 12)

→ (48 + 12) ÷ 2

→ 60 ÷ 2 = 30.

Hence, the correct answer is "Option 1".

The correct answer is Shahdol.

Key Points

Scheduled Tribes (ST) of Madhya Pradesh

• Article 342(1) and Article 366 (Section 25) of the Indian Constitution mentions "Scheduled Tribes".
• MP is the residence of almost 46 ST, including 200 Subtribes.
• Division-wise Shahdol consists of the highest (46.1%) and Chambal the lowest (4.2%) ST population. Hence option 1 is correct.
• The total population of ST in MP is 15,316,784 (21.1% of the total population of the state).
• The sex ratio of ST is 984.
• The literacy rate of ST is 50.6%.
• Bhil, Gond and Kol are the largest tribes of MP.
• ​Bhil amongst the three is the largest tribe of the state.

The correct answer is 1 : 8.

Key Points

• The resistance (R) of a wire is given by the formula R = ρ(L/A), where ρ is the resistivity, L is the length, and A is the cross-sectional area.
• Since both wires have the same length and resistance, we can set up a ratio for their resistivities based on their cross-sectional areas.
• The ratio of their cross-sectional areas is 1 : 8, implying one wire has a cross-sectional area 8 times larger than the other.
• Given that resistance is inversely proportional to the area (A), the wire with the larger area will have a lower resistivity if all other factors are constant. However, since their resistances are the same and lengths are equal, the only way to balance the equation is if their resistivities are directly proportional to their areas, resulting in the ratio of resistivities being  ρ = R(A/L)
• \(\rho \propto \text{Area} \\ A_1:A_2=1:8 \\ \implies \rho_1:\rho_2=1:8 \ \ \)

Additional Information

Resistivity is a fundamental property of materials that quantifies how strongly a material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is specific to each material and influences how it is used in electrical and electronic applications. For example:

• Copper has a low resistivity, making it an excellent choice for electrical wiring.
• Rubber, on the other hand, has a high resistivity, which makes it an effective insulator.
• The resistivity of materials can be affected by temperature; in most metals, resistivity increases with temperature.
• Semiconductors have resistivities that fall between those of conductors and insulators, which can be altered by doping with impurities and changes in temperature.

The pattern followed here is:-

For 83 : 169

83 × 2 + 3 = 169

Similarly,

For 99 : ?

99 × 2 + 3 = 201

Hence, '201' is the term related to the third term in the same way as the second term is related to the first term.

Hence, '201' is the correct answer.
