Shortcut Trick

In a right-angled triangle ΔABC with an altitude CD drawn to the hypotenuse AB, the angle ∠ACD is always complementary to ∠A.

⇒ ∠ACD = 90° − ∠A

⇒ ∠ACD = 90° − 55°

⇒ ∠ACD = 35°

∴ The correct answer is 35°.

Alternate Method

Given:

ΔABC is right-angled at C (∠ACB = 90°).

CD is perpendicular to AB (CD ⊥ AB).

∠A = 55°.

Formula Used:

In any triangle, the sum of all interior angles is 180°.

Calculations:

Consider the small triangle ΔADC.

⇒ In ΔADC, we have three angles: ∠A, ∠ADC, and ∠ACD.

⇒ Since CD ⊥ AB, the angle ∠ADC is 90°.

⇒ Sum of angles in ΔADC = 180°

⇒ ∠A + ∠ADC + ∠ACD = 180°

⇒ 55° + 90° + ∠ACD = 180°

⇒ 145° + ∠ACD = 180°

⇒ ∠ACD = 180° − 145°

⇒ ∠ACD = 35°

∴ The correct answer is 35°.

Additional Information

Similarity in Right Triangles

When an altitude is drawn to the hypotenuse of a right triangle, the two smaller triangles formed are similar to the original triangle and to each other (ΔACD ∼ ΔCBD ∼ ΔABC).

Angle Relationships

In the configuration above, the angles are related as: ∠ACD = ∠B and ∠BCD = ∠A.

Right Triangle Complementary Angles

The two acute angles of any right-angled triangle are always complementary, meaning their sum is exactly 90°.

Given:

Distance covered by cyclist = d

Time taken by cyclist = t

Distance covered by jogger = d/2

Time taken by jogger = 2t

Formula:

Speed = Distance / Time

Calculation:

Cyclist speed = d / t

Jogger speed = (d/2) / (2t) = d / (4t)

Ratio of cyclist speed to jogger speed:

⇒ (d / t) / (d / (4t)) = (d/t) × (4t/d) = 4/1

Ratio = 4:1

Given

Shortcut Trick

The vertices (a, b + c) and (a, b − c) share the same x-coordinate, forming a vertical base.

Base length = |(b + c) − (b − c)| = |b + c − b + c| = 2c.

The height of the triangle is the horizontal distance from the third vertex (−a, c) to the line x = a.

Height = |a − (−a)| = 2a.

Area = 1/2 × Base × Height = 1/2 × 2c × 2a = 2ac.

∴ The correct answer is 2ac.

Alternate Method

Given: Vertices of the triangle are (x₁, y₁) = (a, b + c), (x₂, y₂) = (a, b − c), and (x₃, y₃) = (−a, c).

Formula Used: Area = 1/2 |x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂)|

⇒ Area = 1/2 |a((b − c) − c) + a(c − (b + c)) + (−a)((b + c) − (b − c))|

⇒ Area = 1/2 |a(b − 2c) + a(c − b − c) − a(b + c − b + c)|

⇒ Area = 1/2 |ab − 2ac + a(−b) − a(2c)|

⇒ Area = 1/2 |ab − 2ac − ab − 2ac|

⇒ Area = 1/2 |−4ac|

⇒ Area = 2ac

∴ The correct answer is 2ac.

Additional Information

Area of Triangle (Coordinate Geometry)

The area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃) is given by 1/2 |x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂)|.

Condition for Collinearity

Centroid of a Triangle

The centroid G(x, y) is the point of intersection of medians, calculated as x = (x₁ + x₂ + x₃)/3 and y = (y₁ + y₂ + y₃)/3.

The logic followed here is:-

1. 729 = 9³
2. 343 = 7³
3. 256 = 16²
4. 512 = 8³

Hence, "option 3" is the correct answer.

(8x + 35x)/1400 + {[x - (9x/14)] × 6/100} = 730

43x/1400 + {[(14x - 9x)/14] × 6/100} = 730

43x/1400 + [5x/14] × 6/100 = 730

(43x/1400) + (30x/1400) = 730

(43x+ 30 x)/1400 = 730

73x/1400 = 730

x = (730 × 1400)/73

x = 14000

∴ Total sum is Rs.14,0000

Given

cost of wheat 1 quintal = Rs.1200

Transportation cost = Rs.10,000

selling price of wheat per Kg = Rs.13

Formula used

Profit = Selling price - Cost price

profit % = (profit/cost price) × 100

1 quintal = 100 Kg

Calculation

Total cost of wheat of 200 quintals = 1200 × 200 + 10,000

⇒240,000 + 10,000

⇒2,50,000

Cost of 1 Kg wheat = 2,50,000/(200 × 100)

⇒Rs 12.50

Selling Price of 1 Kg wheat = Rs.13

Profit per Kg = Rs 13 - Rs.12.50

⇒Rs. 0.50

Profit % = (0.50/12.50) × 100

⇒4%

∴ The profit % of dealer is 4.

• On January 1, 1949, the RBI was nationalized.
• Functions of RBI:
• Issue of Bank Notes: The Reserve Bank of India has sole authority to issue currency notes, with the exception of one rupee note, which is issued by the Ministry of Finance. The Reserve Bank's currency notes have been designated unlimited legal tender throughout the country.
• Banker to Government: It is responsible for maintaining and operating the government's deposit accounts. It is responsible for collecting funds and making payments on behalf of the government. As a member of the IMF and the World Bank, it represents the Indian government.
• Custodian of Cash Reserves of Commercial Banks: The commercial banks hold deposits in the Reserve Bank and the latter has the custody of the cash reserves of the commercial banks.
• Custodian of Country’s Foreign Currency Reserves: The Reserve Bank is in charge of the country's international currency reserves, which allows it to deal with crises related to a negative balance of payments position.
• Lender of Last Resort: Commercial banks seek the Reserve Bank in times of financial distress, and the Reserve Bank steps in to help them, even if it means charging a higher rate of interest.
• Central Clearance and Accounts Settlement: Because commercial banks deposit their excess cash reserves with the Reserve Bank, it is easier for them to engage with one another and satisfy their claims on one another through Reserve Bank bookkeeping entries. The Reserve Bank's clearance of accounts has now become a critical role.
• Controller of Credit: Since credit money forms the most important part of the supply of money, and since the supply of money has important implications for economic stability, the importance of the control of credit becomes obvious. Credit is controlled by the Reserve Bank in accordance with the economic priorities of the government.
• SEBI (Securities and Exchange Board of India) promotes the development of securities market.

The correct answer is Rearing of animals and cultivation of crops together.

Key Points

• Mixed farming is a kind of cultivating that includes both the harvesting of crops and raising animals.
• It is carried out across Asia and nations like India, Afghanistan, South Africa, Malaysia, Indonesia, China, Canada, Central Europe, and Russia.
• Features of mixed farming:
• Animal pasture is set aside on some of the property. A portion of the farm is set aside for feeding animals or cultivating animal feed in the event that a farm decides to rear its animals in specially designed structures.
• The size of the farms is moderate.
• Fodder is made from crop residue. The farmer uses the agricultural residue after harvesting to save money for animal feed and to obtain high-quality yearly products such as meat and milk.
• Animal manure is applied to the soil to fertilize it. Animal rearing provides the farmer with manure, which he may use on the farm to improve soil fertility, allowing the farmer to boost his harvest and income.
• Mixed crop and livestock farming is mainly practiced in Odisha and Kerala in India.​

Additional Information

• Multiple cropping or multi-cropping is the practice of growing two or more crops in the same piece of land during one growing season instead of just one crop. When multiple crops are grown simultaneously, this is also known as intercropping.

Given:

Time = 3 years

Rate = 8%

Amount for CI = Rs. 4,000

Time for CI = 2 years

Rate for CI = 10%

Formula used:

CI = [P(1 + r/100)^t – P]

SI = (P × R × T)/100

Where, P = Principal, R = Rate of interest and T = Time

Calculation:

According to the question:

CI = [P(1 + r/100)t – P]

⇒ 4,000(1 + 10/100)² – 4,000]

⇒ 4,000(11/10)² – 4,000]

⇒ [(4,000 × 121/100) – 4,000]

⇒ Rs. (4,840 – 4,000)

⇒ Rs. 840

So,

Simple interest is half of Compound interest,

⇒ Simple interest = 840/2 = 420

Now,

SI = (P × R × T)/100

⇒ 420 = (P × 8 × 3)/100

⇒ 420 = 24P/100

⇒ 24P = 42,000

⇒ P = Rs. 1,750

∴ The sum placed on simple interest is Rs. 1,750.

Hence, "option 4" is the correct answer.

The correct answer is Femur.

Key Points

• The longest bone in the human body is the femur. It's called the thigh bone since it's nearly 19.9 inches long.
• Simply gazing at one's thigh will reveal that the femur is the longest bone. It stretches from the hip to just below the knee.
• It acts as a connection point for all of the muscles that work on the hip and knee joints.
• The femur also gives rise to some biarticular muscles, such as the gastrocnemius and plantaris, which bridge two joints.
• The femur is home to 23 muscles that either originate from or insert onto it.
• As femur is a long bone, it has two ends: proximal and distal.
• The end, which lies on the side of the hip, is called proximal femur, and another on the side of knee is referred to as distal femur. The region between these two ends is called the shaft.

Additional Information

• Patella:
• The patella is a small bone located in front of the knee joint — where the thighbone (femur) and shinbone (tibia) meet. It protects the knee and connects the muscles in the front of the thigh to the tibia.
• The ends of the femur and the undersides of the patella are covered with a smooth substance called articular cartilage. This cartilage helps the bones glide easily along each other as you move your knee.
• Sternum: 
• The sternum is a partially T-shaped vertical bone that forms the anterior portion of the chest wall centrally.
• The sternum is divided anatomically into three segments: manubrium, body, and xiphoid process.
• The sternum connects the ribs via the costal cartilages forming the anterior rib cage. The manubrium is the broad superior segment, the body is the middle portion, and the xiphoid process is a narrower distal segment forming the partial T-shape.
• Tibia:
• The tibia is the major bone of the lower leg, which forms the shin.
• It articulates at the knee and ankle joints and expands at its proximal and distal ends. The tibia is the body's second largest bone and a major weight-bearing structure.

Thus, option 4 is the correct answer.

Given:

The given number = 2/11

The reciprocal of -5/14 = -14/5

Calculation:

According to the question:

⇒ (2/11 × -14/5)

⇒ -28/55

∴ The required value is -28/55.

Given:

The two vertices = (2, 4) and (2, 6)

Calculation:

Let the third vertex of an equilateral triangle be (x, y)

In equilateral triangle, all sides have equal length which is AB = BC = AC

So,

⇒ AB = √(2 – 2)² + (6 – 4)²

⇒ √(2)²

⇒ √4

⇒ 2 units

And, AC = √(2 – x)² + (4 – y)² = 2 units ....(1)

BC = √(2 – x)² + (6 – y)² = 2 units ....(2)

Also, AC = BC

⇒ √(2 – x)2 + (4 – y)² = √(2 – x)2 + (6 – y)²  ...(3)

On squaring both the sides

⇒ (2 – x)² + (4 – y)² = (2 – x)² + (6 – y)²

⇒ 16 + y² – 8y = 36 + y² – 12y

⇒ 4y = 20

⇒ y = 5  ...(4)

Now, Putting y = 5 in equation (1)

⇒ √(2 – x)² + (4 – 5)² = 2

⇒ √(2 – x)2 + (-1)² = 2

⇒ √(2 – x)2 + 1 = 2

On squaring both sides

⇒ (2 – x)² + 1 = 4

⇒ (2 – x)² = 3

⇒ (2 – x) = +√3 or -√3

⇒ x = 2 + √3 or 2 – √3

So,

(x, y) = C = (2 + √3, 5)

∴ The required value is (2 + √3, 5).

The correct answer is Data Definition Language.

Key Points

• A data definition language (DDL) is a computer language that is used to build and alter database object structures.

Given:

Radius of circle = 36 cm

4l = 3r

Formula used:

Area of sector = 1/2 × Length of arc × radius

Calculation:

4l = 3r

⇒ 4l = (3 × 36)

⇒ 4l = 108

⇒ l = 27 cm

Now,

Area of sector = 1/2 × Length of arc × radius

⇒ (1/2 × 27 × 36) cm²

⇒ (27 × 18) cm²

⇒ 486 cm²

∴ The required area of the sector is 486 cm².

Given:

$7\frac{8}{9}$ is converted into an improper fraction and its numerator is 70 + x

Calculation:

According to the question:

⇒ $7\frac{8}{9}$ = 71/9

Improper fraction: When the numerator is greater than or equal to the denominator then the fraction is called an Improper fraction 

Now, Numerator = 70 + x

⇒ 70 + x = 71

⇒ x = (71 – 70)

⇒ x = 1

∴ The value of x is 1.

Given:

A, B, C, and D are four persons in a group who have to choose one number from 1 to 10

No two persons can take the same number.

The Cube of the number chosen by A and the Square of the number chosen by C are both within the permitted number range

B has chosen a number that is just one greater than the number chosen by C and D has chosen the smallest number amongst the four persons.

Calculation:

Since, the number choose between 1 to 10 by all the four persons.

Hence, the selected number are chosen by them are as follows

   Person      Chosen number

     A               2 [2³ = 8]

     B               4

     C               3 [3² = 9]

     D               1

The cube of the number 2 chosen by A is 8 and the square of the number 3 chosen by C is a within the range of numbers (1 to 10)

∴ The required number chosen by D is 1.

The correct answer is Trans fat.

Key Points

• Trans fat, also called the worst form of fat in food, is responsible for over 5,00,000 deaths globally from coronary heart disease each year.
• They not only raise bad cholesterol (LDL) levels but also lower good cholesterol (HDL) levels. This increases the risk of developing coronary heart disease and stroke. It also makes individuals prone to a higher risk of developing type 2 diabetes.
• The World Health Organization (WHO) has teamed up with the International Food and Beverage Alliance (IFBA) to achieve the 'REPLACE Strategy' objective of eradicating trans-fat from the global food supply by 2023.
• By 2023, IFBA members have committed to not exceeding the worldwide trans-fat industrial limit of 2 gramme per 100 g fat/oil in their products.
• REPLACE is an abbreviation for WHO’s six strategic actions:
• Review (dietary sources of industrially-produced trans fats),
• Promote (replacement of industrially-produced trans fats with healthier fats,
• Legislate (enact regulatory actions to eliminate industrially-produced trans fats),
• Assess (trans fats content in the food supply),
• Create awareness (about negative health impact of trans fats) and
• Enforce (compliance with policies and regulations).

The correct answer is 44^th

 Key Points

• Articles 19 and 31 of the Constitution originally established the right to property.
• All citizens have the right to acquire, keep, and dispose of property under Article 19.
• "No individual shall be deprived of his property unless by authority of law," according to Article 31. It further stated that a person whose property was taken for public reasons would be compensated.
• The 44^th Amendment of 1978 removed the right to property from the list of fundamental rights.
• A new provision, Article 300-A, was added to the constitution, which provided that "no person shall be deprived of his property save by authority of law".
• Thus, if a legislator made a law depriving a person of his property, there would be no obligation on the part of the State to pay anything as compensation.
• Furthermore, the aggrieved person would also have no right to move the court under Article 32 due to the right to property no longer being a fundamental right.

The correct answer is Ohm.

Key Points

• The unit of the electrical resistance, measured with direct current, is the ohm (Ω), named after the German physicist and mathematician Georg Simon Ohm.
• According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it:  R = U / I.
• Hence it follows: 1 Ω = 1 V/A.
• The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.

Additional Information

• Coulomb:
• The coulomb (C) is the standard unit of electric charge in the International System of Units (SI).
• It is a dimensionless quantity, sharing this aspect with the mole.
• A quantity of 1 C is equal to approximately 6.24 x 1018, or 6.24 quintillion.
• Seimens:
• The siemens (S) is the SI-derived unit of electric conductance and admittance, also known as the mho (ohm spelled backward, ℧); it is the reciprocal of resistance in ohms (Ω).

Given:

$\frac{\sin\spaceθ \space+\space \cos\spaceθ} {\sin \spaceθ \space-\space \cos \spaceθ} = \frac{√3 \space-\space 1}{√3 \space+\space 1}$

Formula used:

tanθ = sinθ/cosθ 

tan 60° = √3

Calculation:

$\frac{\sin\spaceθ \space+\space \cos\spaceθ} {\sin \spaceθ \space-\space \cos \spaceθ} = \frac{√3 \space-\space 1}{√3 \space+\space 1}$

Dividing cosθ in numerator and denominator

⇒ (sinθ/cosθ + cosθ/cosθ)/(sinθ/cosθ – cosθ/cosθ) = √3 – 1/√3 + 1

⇒ (tanθ + 1)/(tanθ – 1) = √3 – 1/√3 + 1

⇒ √3tanθ + √3 + tanθ + 1 = √3tanθ – tanθ – √3 + 1

⇒ √3 + tanθ + 1 + tanθ + √3 – 1 = 0

⇒ 2tanθ + 2√3 = 0

⇒ 2tanθ = -2√3

⇒ tanθ = -√3

⇒ tanθ = -tan 60° 

⇒ tanθ = -tan(360° – 60°)

⇒ tanθ = tan 300° 

⇒ θ = 300° 

∴ The angle θ is 300°.

Shortcut Trick

Put a specific value for angle A where the expression is defined.

Let A = 45° is not possible as denominators become zero. Let A = 30°.

Expression = [tan 30° / (1 − cot 30°)] + [cot 30° / (1 − tan 30°)] = [(1/√3) / (1 − √3)] + [√3 / (1 − 1/√3)]

= [1 / (√3 − 3)] + [3 / (√3 − 1)] = 1 + 2/√3 + 1 = 1 + sec 30° cosec 30°.

∴ The correct answer is 1 + sec A cosec A.

Alternate Method

Given: $\frac{\tan A}{1 \space-\space \cot A} + \frac{\cot A}{1 \space-\space \tan A}$

Formula Used: tan A = sin A / cos A; cot A = cos A / sin A; a³ − b³ = (a − b)(a² + ab + b²)

⇒ [(sin A / cos A) / (1 − cos A / sin A)] + [(cos A / sin A) / (1 − sin A / cos A)]

⇒ [sin² A / (cos A(sin A − cos A))] + [cos² A / (sin A(cos A − sin A))]

⇒ [sin² A / (cos A(sin A − cos A))] − [cos² A / (sin A(sin A − cos A))]

⇒ (sin³ A − cos³ A) / [sin A cos A (sin A − cos A)]

⇒ [(sin A − cos A)(sin² A + cos² A + sin A cos A)] / [sin A cos A (sin A − cos A)]

⇒ (1 + sin A cos A) / (sin A cos A)

⇒ (1 / sin A cos A) + (sin A cos A / sin A cos A) = sec A cosec A + 1

∴ The correct answer is 1 + sec A cosec A.

Additional Information

Fundamental Identities

sin² A + cos² A = 1 | 1 + tan² A = sec² A | 1 + cot² A = cosec² A.

Reciprocal Relations

cosec A = 1 / sin A | sec A = 1 / cos A | cot A = 1 / tan A.

The correct answer is Control unit, ALU, memory.

Key Points

• A central processing unit (CPU), also called a central processor, main processor, or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.
• The three constituents of CPU in a computer are the Control unit, ALU, and memory.
• The arithmetic and logical unit (ALU) is a component that performs arithmetic and logic operations in all computers.
• The ALU is used to perform operations such as addition, subtraction, multiplication, division, number comparison, and Boolean operations.
• It does not deal with instruction sequencing or memory directly.
• A smaller ALU will produce faster results but not always accurate results, whereas a larger one will produce slower but more accurate results.
• ALU is like a bridge between the computer’s primary memory and the secondary memory. All the data and instructions that are exchanged between the primary and secondary memory pass through the Arithmetic and Logic Unit ( ALU ).
• The Control Unit reads the instructions that are stored in its memory and send out electrical signals to each component of the computer, telling them what to do with the data they've been given.
• Control Unit ( CU ) controls the functioning of other hardware components of the CPU like ALU and Registers,.
• A memory or storage unit in a computer is an electronic device that stores data, programs, and other information.
• The two main types of memory are RAM and Hard Drive. RAM stands for Random Access Memory.
• It is a volatile type of storage because it requires power to maintain its contents.
• It is mostly used for temporarily storing data while the computer is on.
• The Hard Drive is non-volatile, meaning it retains stored data even when power isn’t applied to it.
• It can be used to store large amounts of data permanently, so it is important for you to back up your files regularly.
