A. Rs. 5,680

B. Rs. 4,500

C. Rs. 4,000

D. Rs. 5,240

Solutions

Ratio of length and breadth of the triangle = 3x : 2x

As we know,

Area of rectangle = lb

⇒ 3x × 2x = 1350

⇒ 6x² = 1350

⇒ x² = 1350/6

⇒ x² = 225

⇒ x = √225 = 15 m

Length of the rectangle = 3x = 3 × 15 = 45 m

Breadth of the rectangle = 2x = 2 × 15 = 30 m

Perimeter of the rectangle = 2 (l + b) = 2 (45 + 30) = 2 × 75 = 150 m

Cost of fencing 1 m = Rs. 30

Cost of fencing 150 m = 150 × 30 = Rs. 4,500

D. Ovules

Solutions

The carpels(female) and stamens(male) are surrounded by petals.
Carpel- One of the leaflike, seed-bearing structures that constitute the innermost whorl of a flower.
One or more carpels make up the pistil.
Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel.
Carpels, present in the centre of a flower, form the female reproductive part. It is surrounded by male reproductive structures called stamens.
The petals are protected by sepals, which are green.
The carpels are the female reproductive part of the flower. It is divided into three parts namely- ovary, style and stigma.
The ovary contains ovules and the style acts as a passage for the pollen tubes carrying the male gametes.
The stigma is the terminal part of the carpel which is receptive and it receives the pollen grains and provides nutrition for the growth and development of pollen tube which carries male gametes through style and reaches the ovules to fertilise an egg.

The fluid the filled inner ear is called the labyrinth, and the coiled portion of the labyrinth is called cochlea.

The vibrations produced in the eardrum are transmitted through the ear ossicles and oval window to the fluid-filled inner ear.

The inner ear also contains a complex system located above the cochlea called the vestibular apparatus.

It is influenced by gravity and movements and helps us in maintaining the balance of the body and posture.

21. A flight covering a distance of 1200 km could reduce the travel time by 30 minutes, due to an additive tailwind that increases the average speed by 120 km/hr. What was the duration of the flight in hours?

A. 2.2 hours

B. 1.9 hours

C. 1.8 hours

D. 2 hours 30 min

Solutions

Total distance = 1200 km

As we know,

30 min = 1/2 hr

Let the speed of the flight be x km/hr

According to the question

⇒ 1200/x – 12000/(x + 120) = 1/2

⇒ 1200 [(x + 120 – x)/x (x + 120)] = 1/2

⇒ 1200 [120/(x² + 120x)] = 1/2

⇒ 1200 × 120 × 2 = x² + 120x

⇒ 288000 = x² + 120x

⇒ x² + 120x – 288000 = 0

⇒ x² + 600x – 480x – 288000 = 0

⇒ x (x + 600) – 480 (x + 600) = 0

⇒ (x + 600) (x – 480) = 0

Taking

⇒ (x – 480) = 0

⇒ x = 480 km/hr

Total distance = 1200 km

Speed = 480 km/hr

As we know,

Time = Distance/Speed

Time = 1200/480 = 2.5 hr or 2 hr 30 min

22. A clock shows 2 am now. Find the total rotation of the minute hand, in degrees, of the clock when it will show 9 pm on the same night?

A. 8600°

B. 6840°

C. 6470°

D. 5930°

Solutions

No. of hours between 2 am and 2 pm in a day = 12 hours

No. of hours between 2 pm and 9 pm in a day = 7 hours.

Therefore, total no. of hours between 2 am and 9 pm of the same day = 12 + 7 = 19 hours.

Angle rotated by a minute hand in 1 hour = 360°

Therefore, total rotation in 19 hours = 19 × 360° = 6840°

Hence, the correct answer is 6840°.

A. 24 years

B. 28 years

C. 14 years

D. 20 years

Solutions

Let the present ages of two persons be x and y.

The sum of the present age of two person is seven times that of the difference between their ages.

x + y = 7 (x – y)

x + y = 7x – 7y

6x = 8y

x/y = 8/6

x/y = 4/3

x = 4

y = 3

let x and y be 4k and 3k (k is constant term)

After 5 years, the sum of their ages will become nine times that of the difference

4k + 5 + 3k + 5 = 9 {(4k + 5) – (3k + 5)}

7k + 10 = 36k + 45 – 27k – 45

2k = 10

K = 5

X = 4k = 4 × 5 = 20

Y = 3k = 3 × 5 = 15

Hence, elder person is 20 years old.

Hence, the correct answer is option 4.

33. What is the upward force exerted by the water on the bottle containing it called?

A. Tension

B. Buoyant Force

C. Thrust

D. Pressure

Solutions

the correct answer is option 2 i.e Buoyant Force

Buoyant Force:

It is the force that causes objects to float.
It is the upward force applied by the fluid on the object or the body when an object is put in or submerged in the fluid.
It is also known as the buoyant force.
Buoyancy is the phenomenon due to Buoyant Force.
The unit of the buoyant force is the Newton (N).
The buoyant force depends upon the density of the fluid.
Buoyancy is defined as an upward force exerted by any fluid when an object is immersed in it.
The pressure is more on the bottom of the object than the top of the object as the pressure increases with depth.
These forces acting on the body are called the Buoyant force.
Upward pressure exerted by the fluid depends upon the density of a fluid.
The formulae for Buoyant force (f)=ρgv.
Where ρ is the density of the fluid, g is the gravity, and v is the volume of fluid displaced.

Name of the force	Description
Tension	It is the pulling force that is applied axially by a rope, cable, etc.
Thrust force	It is the force that pushes or accelerate the object in one direction. It is based on Newton’s third law of motion
Pressure	It is defined as the force applied perpendicular to the surface of an object per unit area

48. The usual average speed of a car on a particular stretch of road is 75 km/hr. On a particular day, the average speed was 12% less than the usual, as a result of which the time taken was 18 minutes more. How long is the stretch of road, in kilometres?

A. 155

B. 176

C. 165

D. 150

Solutions

Detailed Solution:

18 min = 3/10 hr

Speed = 75 km/hr

Speed after decreasing = 75 × (88/100) = 66 km/hr

Let the distance be D, then

According to the question:

⇒ D/66 – D/75 = 3/10

⇒ D [(75 – 66)/(75 × 66)] = 3/10

⇒ D = (10/3) × (75 × 66)/9 = 165 km

Short trick:

Speed ratio before and after decrement of speed = 75 : 66 = 25 : 22

As we know, Time is inversely proportional to speed, then

Time ratio before and after decrement of speed = 22 : 25

According to the question

⇒ 25 – 22 unit = 18 min

⇒ 3 unit = 18 min

⇒ 22 unit = 6 × 22 = 132 min

So, total time = 132/60 hr

As we know,

Distance = Time × speed

Distance = 132/60 × 75 = 165 km

A. 36 × 10^-6 J

B. 3.6 × 10^-6 J

C. 3.6 × 10⁶ J

D. 36 × 10⁶ J

Solutions

CONCEPT:

Work done (W): When a force is applied on a body and there is a displacement of the body in the direction of force then the work is said to be done by the force.
- The SI unit of work is Joule.
- 1 Joule (J) = 1 Nm

Work (W) = Force (F) × Displacement (S)

Power (P): The rate of work done is called power.

A. m > 9/8

B. m > 8/9

C. m = 9/8

D. m ≤ 9/8

Solutions

Formula Used:

In a quadratic equation ax² + bx + c = 0

If α and β are the roots of the equation then

α + β (Sum of roots) = -b/a, α . β (Product of the roots) = c/a

Calculation:

Let the roots of the equation (l – m)x² – (6l – 6m)x + 1 = 0 be α and 2α.

if we compare the above equation by ax2 + bx + c = 0

we get a = (l – m), b = –(6l – 6m) and c = 1

Now, Sum of roots = -b/a,

Sum of roots (α + 2α) = – { – (6l – 6m)}/(l – m) = 6

⇒ α = 6/3 = 2 —-(1)

Given, l ∶ α = 5 ∶ 8

⇒ l = 5/4

Now, Product of the roots = c/a

Product of the roots α × 2α = 1/(l – m)

⇒ 5/4 – m = 1/8

∴ m = 9/8

80. A sum of money invested for 4 years and 9 months at a rate of 8% simple interest per annum became Rs. 1,035 at the end of the period. What was the sum that was initially invested?

A. Rs. 700

B. Rs. 675

C. Rs. 725

D. Rs. 750

Solutions

Detailed solution:

A = Rs. 1035, time = 4 years and 9 month = 4 + 9/12 = 19/4 years and rate = 8%

As we know,

A = SI + P

A = Prt/100 + P

⇒ 1035 = [P × 8 × (19/4)]/100 + P

⇒ 1035 = 19P/50 + P

⇒ 69P/50 = 1035

⇒ P = 1035 × (50/69) = 750

Short Trick:

Let the principal be 100%

Interest percentage for 1 year = 8%

Interest percentage for 4 years and 9 month = 8 × (4 + 9/12) = 8 × (19/4) = 38%

⇒ 100% + 38% = 1035

⇒ 138% = 1035

⇒ 1% = 7.5

⇒ 100% = 750

81. Which of the following elements has the largest- size atoms?

A. P

A. Metal oxide + acid ⇨ salt + water

B. Metal oxide + acid ⇨ salt + precipitate

C. Metal oxide + acid ⇨ water + gas

D. Metal oxide + acid ⇨ salt + gas

Solutions

The correct answer is option 1 i.e Metal oxide + acid ⇨ salt + water

Metal oxides are basic in nature.
When an acid reacts with a metal oxide they both neutralize each other.
The new compounds formed are salt and water.

Acid + Metal Oxide ⇨ Salt + Water

Example: Calcium is metal and calcium oxide is a metallic oxide which is basic in nature.
When an acid (hydrochloric acid) reacts with calcium oxide, neutralization reaction takes place and calcium chloride along with water is formed.

2HCl + CaO ⇨ CaCl₂ + H₂O

86. Find the value of

A. 9.0

B. 1.2

C. 2.0

D. 0.11

Solutions

As we know,

⇒

⇒ a³ – b³ = (a – b) (a² + b² + ab)

Suppose a = 0.22 and b = 0.11, then

⇒ (a³ – b³) / (a² + b² + ab)

⇒ (a – b) (a² + b² + ab) / (a² + b² + ab)

⇒ (a – b)

⇒ 0.22 – 0.11

⇒ 0.11

87. 4x²+ kx + 5 is divisible by x = 1. The expression is also divisible by

A. 4x – 5

B. x – 5

C. 4x + 5

D. 4x – 1

Solutions

If the expression 4x²+ kx + 5 divisible by x = 1,

⇒ 4x²+ kx + 5 = 0 —-(1)

Put x = 1 in equation (1)

⇒ 4 × 1² + k × 1 + 5 = 0

⇒ 4 + k + 5 = 0

⇒ k = -9

Put the value k in equation

⇒ 4x²– 9x + 5 = 0

⇒ 4x² – 4x – 5x + 5 = 0

⇒ 4x (x – 1) – 5(x – 1) = 0

⇒ (x – 1) (4x – 5) = 0

So, expression divisible by (x – 1) and (4x – 5).

89. The ratio of the ages of the father and the son ten years ago was 11:3. Ten years hence the ratio would be 21: 13. What are the present ages of the father and the son?

A. 32, 16

B. 22, 14

C. 25, 15

D. 32,12

Solutions

Short Trick:

10 unit = 20 years

1 unit = 2 years

10 years ago age of father = 11 × 2 = 22

So, present age of father = 22 + 10 = 32 years

10 years ago age of son = 3 × 2 = 6

So, present age of son = 6 + 10 = 16 years

Detailed Solution:

Let age ratio of father to son ten year ago was = 11x : 3x

According to the question

⇒ (11x + 20)/(3x + 20) = 21/13

⇒ (11x + 20) × 13 = (3x + 20) × 21

⇒ 143x + 260 = 63x + 420

⇒ 143x – 63x = 420 – 260

⇒ 80x = 160

⇒ x = 160/80 = 2

10 years ago father’s age = 11x = 11 × 2 = 22

Father’s present age = 22 + 10 = 32 years

10 years ago son’s age = 3x = 3 × 2 = 6

Son’s present age = 6 + 10 = 16 years

90. ________ has a very high melting and boiling points.

A. Diamond

B. Fullerene

C. Graphite

D. Charcoal

Solutions

The correct answer is option 1 i.e Diamond

Melting Point– The melting point is usually defined as the point at which materials change from a solid to a liquid.
Boiling Point- It is the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure of the liquid’s environment. At this temperature, the liquid is converted into a vapour.
Diamond is made up of carbon-carbon covalent bonds.
A lot of thermal energy is required to break a covalent bond
This makes the diamond’s melting point and boiling point very high.

99. The plant part moves toward light, it is called _________.

A. Positive phototropism

B. Negative tropism

C. Positive tropism

D. Negative phototropism

Solutions

Option 1 is correct:

Phototropism is the ability of a plant or other photosynthesizing organism, to grow directionally in response to a light source.
Plant and other autotrophs need to manufacture their own food; they usually do this through photosynthesis.
Through photosynthesis, organisms convert water, carbon dioxide (CO₂) and light into sugar, which is used for energy and growth.
Plants can not move around to acquire what they need, so in order to maximize the amount of light that they receive through the leaves, they use phototropism.
Positive phototropism is the response of a plant toward a light source, while negative phototropism causes growth in the opposite direction.
If the plant parts i.e. stem moves towards the light, show positive tropism. And if the plant part that is root moves away from light, then it shows negative tropism.
