2. Which place was called the “nursery of the Bengal army”?

A. Awadh

B. Bengal

C. Eastern Uttar Pradesh

D. Punjab

Solutions

The correct answer is Awadh.

Key Points

Awadh was called the “nursery of the Bengal army”.
Awadh known in British historical texts as Avadh or Oudh is a region and proposed state in the modern Indian state of Uttar Pradesh.
The changes that the families of the sepoys saw around them and the threats they perceived were quickly transmitted to the sepoy lines.
The large majority of the sepoys of the Bengal Army were recruited from the villages of Awadh and eastern Uttar Pradesh. Many of them were Brahmins or from the “upper” castes. Awadh was, in fact, called the “nursery of the Bengal Army’’.

Additional Information

Some following facts, Awadh was called “nursery of the Bengal army”:-
The Bengal Army of the East India Company was mainly recruited from high castes living in Bengal, Bihar, and the Awadh.
The sepoys were Indian soldiers who were recruited into the Company’s army just before the rebellion of 1857.
The Bengal Army recruited higher castes, such as Brahmins, Rajputs, and Bhumihar, mostly from the Awadh and Bihar regions, and even restricted the enlistment of lower castes in 1855. A practice that continued for the next 75 years.

3. If , 6(sec2 59° – cot2 31°] + 2/3 × sin 90° – 3 × tan2 56° × y × tan2 34° = y/3 then the value of y is:

A. 2

B. 3

C. 1

D. 4

Solutions

Given:

6(sec2 59° – cot2 31°] + 2/3 × sin 90° – 3 × tan2 56° × y × tan2 34° = y/3

Formulas used:

cosec(90°- A) = sec A

tan(90° – A) = cot A

cosec2A- cot2 A = 1

Calculation:

6(sec2 59° – cot2 31°] + 2/3 × sin 90° – 3 × tan2 56° × y × tan2 34° = y/3

⇒ 6[sec²(90°- 31°) – cot² 31°] + 2/3 × 1 – 3 × tan²(90°- 34°) × y × tan234° = y/3

⇒6[cosec²31°- cot2 31°] + 2/3 – 3 × cot²34°× y × tan234° = y/3

⇒ 6 × 1 + 2/3 – 3 × 1/tan234°× tan234° × y = y/3

⇒ 6 + 2/3 – 3y = y/3

⇒ 20/3 = y/3 + 3y

⇒ 20/3 = 10y/3

⇒ 20 = 10y

∴ y = 2

4. Which gas is needed for photosynthesis?

A. Carbon dioxide

B. Oxygen

C. Hydrogen

D. Carbon mono oxide

Solutions

The correct answer is Carbon dioxide.

Key Points

Carbon dioxide gas is needed for photosynthesis.
The raw materials required for photosynthesis are carbon dioxide, water, and sunlight primarily.
Plants take in carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
During photosynthesis in the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Additional Information

Gas	Use in photosynthesis
Oxygen	Oxygen is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH. the energy source and reducing power for plant metabolism.
Hydrogen	During photosynthesis, Hydrogen ions are vital in both aiding proton gradients to help drive the electron transport chain, and for plant respiration. Hydrogen is necessary for building sugars and other molecules to produce glucose for plant energy.
Carbon mono oxide	Carbon monoxide does not poison plants since it is rapidly oxidized to form carbon dioxide which is used for photosynthesis.

5. A alone can complete a work in 10 days and B can complete it in 15 days. A and B undertake the work for Rs. 4,800. With the help of C, they complete the work in 5 days. What amount is to be paid to C?

A. Rs. 700

B. Rs. 1200

C. Rs. 800

D. Rs. 600

Solutions

Given:

Time taken by A to do a work = 10 days

Time taken by B to do the same work = 15 days

Time taken by A, B and C do the same work = 5 days

Amount of earning = Rs.4800

Formula used:

Ratio of shares of A, B and C = Ratio of their Efficiency

Calculation:

Let total work be = 1 unit

One day work done by A = 1/10

One day work done by B = 1/15

One day work done by A, B and C = 1/5

⇒ One day work done by C = 1/5 – (1/10 – 1/15)

⇒ 1/30

Ratio of shares of A, B and C = Ratio of their one-day work efficiency

⇒ A : B : C = 1/10 : 1/15 : 1: 30

⇒ A : B : C = 3 : 2 : 1

∴ C’s share in earning = Rs.4800 × 1/6

⇒ Rs.800

6. Find the area of a rhombus whose side is 10 cm and the longest diagonal is 16 cm.

A. 88 cm²

B. 96 cm²

C. 86 cm²

D. 94 cm²

Solutions

Given:

Side of a rhombus = 10 cm

Length of longest diagonal = 16 cm

Concept:

A rhombus has equal sides and its diagonals are perpendicular bisectors.

Formulas used:

Area of a rhombus = 1/2 × D1 × D2 [D1 and D2 are diagonals]

Calculation:

By Pythagoras Theorem

In triangle ABO, AB² = AO² + BO²

⇒ 10² = 8² + BO2

⇒ BO = √(100 – 64) = √36

⇒ BO = 6

BD = 2 × BO = 2 × 6 = 12 cm

∴ The area of rhombus = 1/2 × 16 cm × 12 cm

⇒ 96 cm²

7. The compound interest on a certain sum of money at the rate of 11% p.a. for 2 years is Rs. 4642. Find its simple interest at the same rate and for the same period.

A. Rs. 4400

B. Rs. 3500

C. Rs. 4500

D. Rs. 4200

Solutions

Given:

Compound Interest on a sum for 2 years at 11% p.a. = Rs.4642

Formulas used:

Compound Interest + Principal = Amount

⇒ Amount = Principal × (1 + R/100)ⁿ

Simple Interest = Principal × Rate/100 × Time

Calculation:

4642 + P = P × (1 + 11/100)²

⇒ 4642 = P × 111/100 × 111/100 – P

⇒ 4642 = P(111/100 × 111/100 – 1)

⇒ 4642 = P(12321 – 10000)/10000

⇒ 4642 = P × 2321/10000

⇒ P = 4642 × 10000/2321

⇒ P = Rs.20000

∴ Simple Interest = 20000 × 11/100 × 2 = Rs.4400

Alternate Method Percentage Method Compound interest and simple interest both are calculated on Principal. Effective rate percent of compound interest for 2 years = R + R + (R × R)/100

⇒ 11 + 11 + (11 × 11)/100

⇒ 22 + 1.21 = 23.21%

Simple interest rate percent for 2 years = Rate % × Time = 11% × 2 = 22%

23.21% of Principal = Rs.4642

⇒ 22% of Principal = Rs.4642 × 22%/23.21% = Rs.4400

∴ The simple interest is Rs.4400.

A. 10%

B. 21%

C. 20%

D. 15%

Solutions

Given:

Length of side of a square increases by 10%

Formula used:

Area of square = (Side)²

Calculation:

Let the side of square be = 10 units

Area of the old square = 10 × 10 = 100 sq. units

⇒ Increased side of the square = 10 × 110/100 = 11 units

Area of the new square = 11 × 11 = 121 sq. units

Percentage increase of area = (New Area – Old Area)/Old Area × 100

∴ The required increase in the area = (121 – 100)/100 = 21/100 × 100 = 21%

Alternate Method Effective rate of increase = 10% + 10% + (10% × 10%)/100

⇒ 20% + 1% = 21%

⇒ b² = 2437 – 2401 = 36

⇒ b = √36 = ± 6

∴ The other number is + 6.

23. Ramesh Sharma borrows Rs. 8,000 for 3 years at 5% p.a. simple interest. He lends it to Manohar at 7% p.a. for 3 years. Find his gain.

A. Rs. 580

B. Rs. 480

C. Rs. 450

D. Rs. 460

Solutions

Given:

Principal of Rs.8000 borrowed for 3 years at 5% p.a. and the same sum was lent at 7% p.a. for the same time.

Formula used:

Simple Interest = P × R/100 × T

Calculation:

Simple Interest paid by Ramesh = 8000 × 5/100 × 3 = Rs.1200

Simple Interest earned by Ramesh = 8000 × 7/100 × 3 = Rs.1680

∴ Gain earned by Ramesh = Interest earned – Interest paid

⇒ 1680 – 1200 = Rs.480

Alternate Method Total interest percent = R% × T

Total interest percent to be paid = 5% × 3 = 15%

Total interest percent to be earned = 7% × 3 = 21%

Ramesh’s gain = 21% – 15% = 6%

∴ Gain in Rs. = 8000 × 6/100 = Rs.480

24. A train covers 400 km at a uniform speed. If the speed had been 10 km/h more, it would have taken 2 h less for the same journey. Find the speed of the train.

A. 40 km/h

B. 50 km/h

C. 55 km/h

D. 45 km/h

Solutions

Given:

Distance covered = 400 km

Formula used:

Time = Distance/Speed

Calculation:

Let the speed of the train be = a km/h

As per the question;

400/a – 400/(a + 10) = 2

⇒ 1/a – 1/(a + 10) = 2/400

⇒ (a + 10 – a)/a(a + 10) = 1/200

⇒ 10/a(a + 10) = 1/200

⇒ a² + 10a = 2000

⇒ a2 + 10a – 2000 = 0

⇒ a2 + 50a – 40a – 2000 = 0

⇒ a(a + 50) – 40(a + 50) = 0

⇒ (a – 40)(a + 50) = 0

⇒ a = 40, a ≠ – 50

∴ The speed of the train is 40 km/h.

Alternate Method By Value Putting Method;

By using the following equation.

⇒ 400/a – 400/(a + 10) = 2

Option 1: For a = 40, 400/40 – 400/(40 + 10) = 2

Option 2: For a = 50, 400/50 – 400/(50 + 10) ≠ 2

Option 3: For a = 55, 400/55 – 400/(55 + 10) ≠ 2

Option 4: For a = 45, 400/45 – 400/(45 + 10) ≠ 2

34. The smallest six-digit number which is completely divisible by 4, 8, 12 and 16 is:

A. 100032

B. 100900

C. 100800

D. 100700

Solutions

Given:

Smallest six-digit number which is divisible by 4, 8, 12 and 16.

Concept:

LCM (Lowest Common Multiple)

Dividend = Divisor × Quotient + Remainder

Calculation:

LCM of 4, 8, 12 & 16 will be calculated by writing them as the product of their prime factors.

4 = 2²

8 = 2³

12 = 2² × 3

16 = 2⁴

So, LCM (4, 8, 12, 16) = 2⁴ × 3 = 48

The smallest six-digit number is 100000.

By dividing 100000 by 48, we get the remainder 16.

So, we need to add the difference between the Divisor and Remainder to 100000 (Dividend) in order to get the smallest six-digit number divisible by 48.

⇒ 100000 + (48 – 16) = 48 × 2083 + 16 + (48 – 16)

⇒ 100032 = 48 × 2083 + 16 + 32

⇒ 100032 = 48 × 2083 + 48

∴ The smallest six-digit number which is completely divisible by 4, 8, 12 and 16 is 100032.

A. Rs. 60

B. Rs. 45

C. Rs. 40

D. Rs. 50

Solutions

Given:

Reduction percent in the price of wheat = 25%

Expenses on wheat = Rs.600

Formula used:

Expense = Price × Quantity

⇒ Quantity = Expense/Price

Calculation:

Let the original price = Rs.100a per kg

⇒ The reduced price of wheat = 100a × 75/100 = Rs.75a per kg

600/75a – 600/100a = 5

⇒ 104/3a – 26/a = 5

⇒ 8/a – 6/a = 5

⇒ 2/a = 5

⇒ a = 2/5

∴ The original price per kg = 100a = 100 × 2/5 = Rs.40

Alternate MethodBy Ratio Method

25% = 25/100 = 1/4

Original Quantity = 3 × 5 = 15 kg

Expense = Rs.600

∴ Original price of wheat per kg = Rs.600/15 = Rs.40

52. From an external point P, tangents PA and PB are drawn to a circle with centre O. If ∠PAB= 55°, find ∠AOB.

A. 110°

B. 100°

C. 35°

D. 125°

Solutions

Given:

PA and PB are the tangents to the circle with centre O.

∠PAB= 55°

Concept:

Tangents drawn from the same external point are equal in length.

A tangent perpendicular to the radius at the point of tangency.

Calculation:

∵ ∠PAB = 55°

∴ ∠PBA = 55° (PA = PB)

In triangle PAB,

∠APB + ∠PAB + ∠PBA = 180° (Angle Sum Property)

⇒ ∠P + 55° + 55° = 180°

⇒ ∠P = 70°

Also, ∠AOB + ∠APB = 180° (Sum of all the angles of a quadrilateral is 360° & ∠P = ∠B = 90°)

⇒ ∠AOB = 180° – 70° = 110

∴ The measure of ∠AOB = 110°

53. The three laws of motion were proposed by:

A. Galileo

B. Aristole

C. Edison

D. Newton

Solutions

The correct answer is Newton.

Key Points

The three laws of motion were proposed by Sir Isaac Newton.
Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England.
Newton’s three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.
In developing his three laws Newton simplified objects, reducing them to mathematical points without size or rotation to let him ignore factors such as friction, air resistance, temperature, and material properties, and focus on outcomes that can be illustrated wholly with reference to mass, length and time.
In 1687, Newton published Philosophiae Naturalis Principia Mathematica, most often known as Principia. Principia offers an exact quantitative description of bodies in motion, with three basic but important laws of motion:-

First Law A stationary body will stay stationary unless an external force is applied to it.
Second Law Force is equal to mass times acceleration, and a change in motion (i.e., change in speed) is proportional to the force applied.
Third Law For every action, there is an equal and opposite reaction.

A. 36 kg

B. 28 kg

C. 30 kg

D. 34 kg

Solutions

Given:

The average weight of A, B, C, and D = 56 kg

The average weight of A, B, and C = 52 kg

The average weight of C and D = 48 kg

Formula used:

Average weight = Total weight/No of persons

Calculation:

Total weight of A, B, C, & D = 56 kg × 4 = 224 kg (1)

Total weight of A, B, & C = 52 kg × 3 = 156 kg (2)

Total weight of C and D = 48 kg × 2 = 96 kg (3)

By (2) + (3) – (1)

⇒ (A + B + C) + (C + D) – (A + B + C + D) = 156 kg + 96 kg – 224 kg

⇒ A + B + 2C + D – A – B – C – D = 28 kg

⇒ C = 28 kg

∴ The weight of C is 28 kg.

56. The least number which should be added to 4707 so that the sum is exactly divisible by 4, 5, 6 and 8 is:

A. 83

B. 73

C. 63

D. 93

Solutions

Given:

Number = 4707

Concept:

Dividend = Divisor × Quotient + Remainder

LCM = Lowest Common Multiple

It is the smallest positive number that is divisible by two or more numbers.

Calculation:

To find the least number which can be added to 4707 that is exactly divisible by 4, 5, 6 and 8, we need to find the LCM of these 4 numbers.

LCM of 4, 5, 6 and 8 can be calculated by prime factorization;

4 = 2²

5 = 5

6 = 2 × 3

8 = 2³

⇒ LCM (4, 5, 6, 8) = 2³ × 3 × 5 = 120

When divided 4707 by 120, we get

⇒ 4707 = 120 × 39 + 27

By adding the difference of Divisor and remainder (120 – 27) = 93

⇒ 4707 + 93 = 120 × 39 + 27 + 93

⇒ 4800 = 120 × 39 + 120

⇒ 4800 = 120 (39 + 1)

⇒ 4800 = 120 × 40

∴ The least number that should be added to 4707 so that the sum is exactly divisible by 4, 5, 6 and 8 is 93.

58. What is the full form of COBOL?

A. Common Business Organised Language

B. Computer Business Oriented Language

C. Computer Basic Operation Language

D. Common Business Oriented Language

Solutions

The correct answer is Common Business Oriented Language.

Key Points

The full form of COBOL is Common Business Oriented Language.
COBOL (Common Business-Oriented Language) is a high-level programming language for business applications.
COBOL was the first popular language designed to be operating system-agnostic and is still in use in many financial and business applications today.
COBOL is primarily used in business, finance, and administrative systems for companies and governments.
Today many federal government agencies local banks, COBOL is still in use. For example, an estimated 43% of banking systems and 95% of ATM swipes utilize COBOL code.

Additional Information

74. The perimeter of a right triangle is 60 cm and its hypotenuse is 26 cm. Find the area of the triangle.

A. 240 cm²

B. 180 cm²

C. 160 cm²

D. 120 cm²

Solutions

Given:

Perimeter of a right triangle = 60 cm

Hypotenuse = 26 cm

Formulas used:

(x + y)² = x² + y² + 2xy

Perimeter of the right-angle triangle = Base + Height + Hypotenuse

Pythagoras Theorem:

Base² + Height² = Hypotenuse²

Area of right-angle triangle = 1/2 × Base × Height

Calculation:

Let the base and height be x and y respectively

Sum of base and height (x + y) = 60 – 26 = 34 cm (1)

Also, x² + y² = 26²

⇒ x2 + y2 = 676 (2)

From (1)

(x + y) = 34

By squaring both sides;

⇒ x2 + y2 + 2xy = 1156

⇒ 676 + 2xy = 1156 ∵ [x2 + y2 = 676]

⇒xy = (1156 – 676)/2

⇒ xy = 240 (3)

∴ Area of right-angle triangle = 1/2 × 240 = 120 cm²

75. If a² + b² = 82 and ab = 9, Find the value of a³ + b³.

A. 720

B. 830

C. 730

D. 750

Solutions

Given:

a2 + b2 = 82

ab = 9

Formulas used:

(a + b)² = a² + b² + 2ab

(a + b)³ = a³ + b³ + 3ab(a + b)

Calculation:

(a + b)2 = 82 + 2 × 9

⇒(a + b)2 = 100

⇒ (a + b) = √100 = 10 (1)

(a + b)3 = a3 + b3 + 3ab(a + b)

⇒ 10³ = a3 + b3 + 3 × 9 × 10

⇒ 1000 = a3 + b3 + 270

⇒ a3 + b3 = 1000 – 270

∴ a3 + b3 = 730

Alternate Method By using formula a3 + b3 = (a + b)(a² – ab + b²)

⇒ a3 + b3 = 10 × (82 – 9) = 10 × 73

∴ a3 + b3 = 730

80. What is the momentum of an object having mass of 14 kg and velocity 28 m/s?

A. 1/392 kg-m/s

B. 2 kg-m/s

C. 0.5 kg-m/s

D. 392 kg-m/s

Solutions

The correct answer is 392 kg-m/s.

Key Points

The momentum of a particle is a measure of the time required for a constant force to bring it to rest.
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
- Momentum = Mass * Velocity
In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as p = m • v.
Momentum is a vector quantity; i.e., it has both magnitude and direction.

Additional Information

Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
Conservation of momentum can be described by P1 (before) + P2 (before) = P1 (after) + P2 (after).
Some of the examples of momentum include –
- A train moving at 100 km/h.
- A bullet fired from a gun.
- A baseball flying through the air.

81. A man bought 2 articles for Rs. 3,000 each. He sold one article at 10% profit and another at 5% profit. Find the total percentage profit he earned.

A. 15%

B. 6.5%

C. 7.5%

D. 8.5%

Solutions

Given:

Cost Price of two articles = Rs.3000 each

Profit on one article = 10%

Profit on another article = 5%

Formulas used:

Selling Price = Cost Price × (100 + Profit)/100%

Profit = Selling Price – Cost Price

Profit percent = Profit/Cost Price × 100

Calculation:

Selling Price of one article at 10% profit = 3000 × 110/100 = Rs.3300

Selling Price of another article at 5% profit = 3000 × 105/100 = Rs.3150

Total Selling Price of both articles = 3300 + 3150 = Rs.6450

Total Cost Price of both articles = Rs.3000 + Rs.3000 = Rs.6000

Profit on both articles = Rs.6450 – Rs.6000 = 450

∴ Profit Percent on both articles = 450/6000 × 100

⇒ 7.5%

Alternate MethodBy Average MethodWhen the Cost Price of both the articles is equal;

Average or aggregate profit on two articles = (Profit1 + Profit2)/2

⇒ (10% + 5%)/2 = 15%/2

⇒ 7.5%
