Given:

The electricity bill of a certain establishment is partly fixed and partly variable depending on the number of units of electricity consumed.

In a certain month when 540 units were consumed, the bill was Rs. 1,800.

In another month when 620 units were consumed, the bill was Rs. 2,040.

Formula used:

Let the fixed cost be F and the variable cost per unit be V.

Total Bill = Fixed Cost + (Variable Cost per unit × Number of units)

Calculation:

1,800 = F + 540V

2,040 = F + 620V

Subtracting the first equation from the second:

2,040 - 1,800 = (F + 620V) - (F + 540V)

⇒ 240 = 80V

⇒ V = 240/80

⇒ V = 3

Substituting the value of V in the first equation:

1,800 = F + 540 × 3

⇒ 1,800 = F + 1,620

⇒ F = 180

If in a month 500 units are consumed, then:

Bill = F + 500V

⇒ Bill = 180 + 500×3

⇒ Bill = 180 + 1,500

⇒ Bill = 1,680

∴ The correct answer is option 1.

Given:

If $\dfrac{1}{8}$ of a pencil is black, half of the remaining pencil is yellow and the remaining $3\dfrac{1}{2}$ cm of the pencil is blue.

Formula used:

Let total length of pencil = x cm

Black part = $\dfrac{1}{8}$ x cm

Remaining length = $x - \dfrac{1}{8}x = \dfrac{7}{8}x$ cm

Yellow part = $\dfrac{1}{2} \times \dfrac{7}{8}x = \dfrac{7}{16}x$ cm

Blue part = $3\dfrac{1}{2} = \dfrac{7}{2}$ cm

Calculation:

x = $\dfrac{1}{8}x + \dfrac{7}{16}x + \dfrac{7}{2}$

⇒ $x = \dfrac{2}{16}x + \dfrac{7}{16}x + \dfrac{7}{2}$

⇒ $x = \dfrac{9}{16}x + \dfrac{7}{2}$

⇒ $x - \dfrac{9}{16}x = \dfrac{7}{2}$

⇒ $\dfrac{7}{16}x = \dfrac{7}{2}$

⇒ $x = \dfrac{7}{2} \times \dfrac{16}{7}$

⇒ x = 8 cm

∴ The correct answer is option 2.

Given:

Minimum marks required to pass = 33%

Marks obtained by candidate = 210

Marks candidate failed by = 21

Formula used:

Let the total marks be x

Pass marks = 33% of total marks = 0.33x

Calculation:

Since the candidate fails by 21 marks:

210 + 21 = 0.33x

⇒ 231 = 0.33x

⇒ x = $\dfrac{231}{0.33}$

⇒ x = 700

Given:

Amount after 2 years (A1) = ₹720

Amount after 7 years (A2) = ₹1020

Time difference = 5 years

Formula used:

Simple Interest (SI) = P × R × T / 100

Amount (A) = Principal (P) + Simple Interest (SI)

Calculations:

Let the principal be P and rate be R.

For the first 2 years:

720 = P + (P × R × 2 / 100)

⇒ 720 = P(1 + 2R/100)

For the next 5 years:

1020 = P + (P × R × 7 / 100)

⇒ 1020 = P(1 + 7R/100)

Now, subtract the first equation from the second:

1020 - 720 = P(1 + 7R/100) - P(1 + 2R/100)

⇒ 300 = P(5R/100)

⇒ P × 5R/100 = 300

⇒ P × R = 6000

Substitute P × R = 6000 in the first equation:

720 = P(1 + 2R/100)

⇒ 720 = P + (2 × 6000 / 100)

⇒ 720 = P + 120

⇒ P = 720 - 120

⇒ P = 600

∴ The correct answer is option 2.

Given:

Three whole cakes weigh 4(1/2) lbs, 6(3/4) lbs, and 7(1/5) lbs, respectively.

Formula used:

To find the maximum number of guests that can be served, we need to find the greatest common divisor (GCD) of the weights of the cakes.

Calculations:

First, convert the mixed fractions to improper fractions:

4(1/2) = 9/2

6(3/4) = 27/4

7(1/5) = 36/5

Find the GCD of the denominators 2, 4, and 5:

The GCD of 2, 4, and 5 is 1.

Convert the improper fractions to have a common denominator:

9/2 = 90/20

The correct answer is 27.3 earth days.

Key Points

• Since the moon takes 27.3 days to complete one revolution around the earth and also the period of the rotation of the moon on its axis takes around 27.3 days
• Thus, the rotation time of the moon to rotate on its axis overlaps with its revolution along with the orbital plane. The moon completes 1 rotation on its axis as it completes one revolution around the Earth. As a result, we will see somewhat, Moon always has the same face towards the earth.
• The moon travels around the earth in an elliptical orbit.
• When the moon is closest to earth, its rotation is slower. so an additional 8 degrees are visible on the eastern side.
• When the moon is farthest from the earth, its rotation is faster. so, an additional 8 degrees are visible on the western side.

 Additional Information

• Phases of the moon:
• New Moon: On this day, the moon is between the earth and the sun align in a straight line. And the moon becomes invisible.
• Full moon: On this day, a perfect round-shaped moon appears.
• Crescent Moon: The shape of the moon during the phases between the new moon and half-moon is the crescent moon.
• Gibbous Moon: The shapes of the moon during the phases between the full moon and half-moon are the gibbous moon. Since the moon takes 27.322 days to complete one revolution around the earth and also the period of the rotation of the moon on its axis takes around 27.3 days​​​

The correct answer is Virtual Reality.

Key Points

• Virtual reality creates an immersive artificial world that can seem quite real via the use of technology.
• The simulated environment can be similar to the real world, as in simulations for pilot or combat training, or it can differ significantly from reality.
• Statement 'B' is false as it hasn't been mentioned in the passage that it is easy to create a high-fidelity virtual reality experience.
• It becomes difficult to create a high fidelity due to the limited equipment.
• it is currently very difficult to create a high fidelity virtual reality experience, largely due to technical limitations on processing power, image resolution, and communication bandwidth.

Given:

Out of six consecutive numbers, the sum of the first three numbers is 27.

Formula used:

For six consecutive numbers: x, (x+1), (x+2), (x+3), (x+4), (x+5)

Sum of first three numbers = x + (x+1) + (x+2)

Sum of next three numbers = (x+3) + (x+4) + (x+5)

Calculation:

Given: x + (x+1) + (x+2) = 27

⇒ 3x + 3 = 27

⇒ 3x = 27 - 3

⇒ 3x = 24

⇒ x = 8

Sum of next three numbers = (x+3) + (x+4) + (x+5)

⇒ (8+3) + (8+4) + (8+5)

⇒ 11 + 12 + 13

⇒ 36

∴ The correct answer is option 3.

The correct answer is infrasound.

Key Points

• The audible sound for human beings extends from the frequency range of about 20 Hz to 20000 Hz (one Hz = one cycle/s).
• Children under the age of five and some animals, such as dogs can hear up to 25 kHz (1 kHz = 1000 Hz).
• The police use high frequency whistles which dogs can hear but humans cannot.

Additional Information

• Infrasonic sound or Infrasound
• Sounds of frequencies below 20 Hz are called infrasonic sound or infrasound.
• If we could hear infrasound we would hear the vibrations of a pendulum just as we hear the vibrations of the wings of a bee.
• Rhinoceroses communicate using infrasound of frequency as low as 5 Hz. Whales and elephants produce sound in the infrasound range. It is observed that some animals get disturbed before earthquakes. Earthquakes produce low-frequency infrasound before the main shock waves begin which possibly alert the animals.
• Ultrasonic sound or Ultrasound
• Frequencies higher than 20 kHz are called ultrasonic sound or ultrasound.
• Ultrasound is produced by dolphins, bats and porpoises. Moths of certain families have very sensitive hearing equipment. These moths can hear the high frequency squeaks of the bat and know when a bat is flying nearby, and are able to escape capture. Rats also play games by producing ultrasound.
• The ultrasound equipment, familiar to us for investigating and tracking many medical problems, works at frequencies higher than 20,000 Hz.
• Hearing Aid 
• As people grow older their ears become less sensitive to higher frequencies and people with hearing loss may need a hearing aid.
• A hearing aid is an electronic, battery operated device that receives sound through a microphone which converts the sound waves to electrical signals.
• These electrical signals are amplified by an amplifier and the amplified electrical signals are given to a speaker of the hearing aid.
• The speaker converts the amplified electrical signal to sound and sends to the ear for clear hearing.

The correct answer is 1765.

Key Points

• The East India Company acquired the Diwani rights over Bengal in the year 1765.
• This marked a pivotal turning point in Indian history, as it effectively established British control over the region's administration and finances.
• The Diwani, or the right to collect land revenue, was a crucial source of income for the Mughal Empire, and its transfer to the Company signified a significant erosion of Mughal authority.

Additional Information

• The acquisition of the Diwani rights stemmed from the Battle of Buxar,
• It was fought on October 23, 1764, between the British East India Company forces led by Robert Clive and the combined armies of Mir Qasim (the Nawab of Bengal), Shuja-ud-Daulah (the Nawab of Awadh), and the Mughal Emperor Shah Alam II.
• The battle resulted in a decisive British victory, paving the way for the Company to secure the Diwani rights through the Treaty of Allahabad signed on August 12, 1765.
• Under the terms of the treaty, Shah Alam II granted the East India Company the Diwani rights in return for an annual tribute of 26 lakhs of rupees.
• This grant of power allowed the Company to directly collect taxes from the people of Bengal, Bihar, and Orissa, significantly bolstering its financial resources and solidifying its dominance in the region.Under the terms of the treaty, Shah Alam II granted the East India Company the Diwani rights in return for an annual tribute of 26 lakhs of rupees.

Given:

Principal (P) = ₹1,000

Amount (A) = ₹1,440

Time (t) = 2 years

Formula used:

A = P$(1+\frac{r}{100})^t$

Where, r = rate

Calculation:

1440 = 1000 $(1+\frac{r}{100})^2$

⇒ $\frac{1440}{1000}= (1+\frac{r}{100})^2$

⇒ $\frac{36}{25}= (1+\frac{r}{100})^2$

⇒ $\frac{6}{5}= (1+\frac{r}{100})$

⇒ $\frac{6}{5}-1= \frac{r}{100}$

⇒ $\frac{1}{5}= \frac{r}{100}$

⇒ r = 20%

∴ The correct answer is option (2).
