Option 2 is correct.

• Richter scale is a quantitative measurement of the magnitude of an Earthquake.
• It was developed by Charles Richter and Gutenberg in 1935.
• It is a logarithmic scale and can be measured using a seismometer.
• As it is a logarithmic scale, each whole-number increase on the scale represents a tenfold increase in measured amplitude.
• Magnitude level of 8 and higher on a Richter scale means it is a very major earthquake and would cause destruction and loss over large areas.
• Magnitude level of 5.0-5.9 is considered a moderate and magnitude level less than 1.0 to 2.9 is considered a micro-level earthquake and it is generally not felt by people.

The correct answer is Modem.

Key Points

• The modem converts the digital signal into an analog signal.
• It stands for Modulator-Demodulator.
• In day to day activity, it allows a computer or another device, such as a router to connect to the Internet.
• As the name suggests, it first modulates and then demodulates.
• It converts (modulates) an analog signal from a telephone or cable wire to digital data of 1s and 0s. This digital data is recognized by a computer.
• Then, it converts (demodulates) digital data from a computer into an analog signal that can be sent over standard telephone lines.

38 and 57 both are divisible by 19

57/19 = 3 and 38/19 = 2

Hence, N = 2.

Let, Time saved be x hours

According to the question,

(50 + 5) × (5.5 – x) = 50 × 5.5

⇒ 302.5 – 55x = 275

⇒ 55x = 27.5

⇒ x = 0.5

∴ Time save = 0.5 hours = 0.5 × 60 min = 30 minutes

x = 7 – 4√3

⇒ x = 4 + 3 – 4√3

⇒ x = 2² + √3² – 2 × 2 × √3

⇒ x = (2 - √3)²

$\therefore \sqrt x + \frac{1}{{\sqrt x }}$

$\Rightarrow \sqrt {{{\left( {2 - \sqrt 3 } \right)}^2}} + \frac{1}{{\sqrt {{{\left( {2 - \sqrt 3 } \right)}^2}} }}$

$\Rightarrow 2;-;\sqrt 3 + \frac{1}{{2;-;\sqrt 3 }}$

$\Rightarrow 2 - \sqrt 3 + \frac{{\left( {2 + \sqrt 3 } \right)}}{{\left( {2 + \sqrt 3 } \right)\left( {2 - \sqrt 3 } \right)}}$

$\Rightarrow 2 - \sqrt 3 + \frac{{\left( {2 + \sqrt 3 } \right)}}{{4 - 3}}$

⇒ 2 – √3 + 2 + √3

⇒ 4

Given:

Principal, P = Rs. 7500

Number of years, n = 2 years 4 months

Rate of interest, r = 12%

Calculation:

Interest for 1st year = Rs. 7500 × (12/100)

⇒ Rs. 900

Principal for 2nd year = Rs. (7500 + 900)

⇒ Rs. 8400

Interest for 2nd year = Rs. 8400 × (12/100)

⇒ Rs. 1008

Principal for last 4 months = Rs. (8400 + 1008)

⇒ Rs. 9408

Rate of interest for 4 months = (12/3)%

⇒ 4%

Interest for last 4 months = Rs. 9408 × (4/100)

⇒ Rs. 376.32

Total interest = Rs. (900 + 1008 + 376.32)

⇒ Rs. 2284.32 ≈ Rs. 2284

∴ The required compound interest is Rs. 2284

Suppose, the one’s digit = y and ten’s digit = x

⇒ The number = 10x + y

According to the question,

x + y = 9   ----(i)

Also,

(10x + y) + 27 = 10y + x

⇒ 9x – 9y = − 27

⇒ x – y = − 3   ----(ii)

From (i) and (ii) we get,

2x = 6

⇒ x = 3

Now, put value of x in (i),

x + y = 9

⇒ 3 + y = 9

⇒ y = 6

∴ The number = 10 × 3 + 6 = 36

The given series is,

13 (+ 1) 14 (+ 4) 18 (+ 9) 27 (+ 16) 43 (+ 25) 68….

Above series is made by adding the squares of numbers from 1, 2, 3, 4 …….

Hence 43 is the missing number.

Kitty’s mother’s brother is her/his maternal uncle.

Kitty’s maternal uncle’s wife = Aunt

So, their daughters are the nieces of the Kitty’s mother and Kitty’s mother is their Aunt.

Uthara is the one of the daughter of Kitty’s maternal Uncle. So Kitty’s mother is the aunt of her sister.

Let, the other two angle be 9x and 16x respectively.

According to the problem,

55° + 9x + 16x =180°      [as sum of all angles of triangle is 180°]

⇒ 25x = 180 – 55°

⇒ x = 125/25 = 5°

∴ The angles are (9 × 5°) = 45° and (16 × 5°) = 80° respectively.

Alternate solution

We can find correct answer of this question by using options.

Sum of all angles must be 180°.

Hence, 55° + 45° + 80° = 180°     (only option D satisfies)

∴ Option D is correct answer.

Option 2 is correct.

Given:

Total income = Rs. 360000

The income of 2nd week making angle on the pie chart = 120° 

Concept used:

The angle made in the centre of the circle is 360° or by one complete rotation is 360°

Here, Angle made at the centre is equal to Rs 360000

Calculations:

Angle made at the centre is equal to Rs 360000

⇒ 360° = 360000 

⇒ 1° = 360000/360° 

⇒ 120° = 120° × (360000/360°)

⇒ 120000

∴ The income of his 2nd week is Rs 120,000

Statement:

Religions teach the guiding principles for leading one’s life.

Conclusions:

I. Religion is a way of life.

(The above conclusion logically follows the statement. Religion is an institution to express belief in a divine power)

II. Religion is a teacher.

(Here teacher refers to a living person and religion is not a person, so it is false.)

From the given conclusion only conclusion I is true, so option A is correct.

H₂O : Hydrogen

Here H₂O represents Dihydrogen Monoxide

So it consists of Hydrogen and Oxygen

Similarly, KOH represents Potassium Hydroxide

So it consists of Potassium, Hydrogen and Oxygen

Hence KOH is related to Potassium.

$\frac{9}{{13}} \div \frac{{18}}{{26}} \div \frac{{90}}{{52}}$

$\Rightarrow \frac{9}{{13}} \times \frac{{26}}{{18}} \div \frac{{90}}{{52}}$

⇒ 1 ÷ 90/52

⇒ 52/90

⇒ 26/45

Option 4 is correct.

CONCEPT:

• Temperature: It is the measure of the degree of hotness and coldness of a body.
• The SI unit of temperature is Kelvin (K).
• The various temperature scales commonly used are Celsius (C), Kelvin (K), Fahrenheit (F), and Rankine (Ra).
• Celsius: It has 100 degrees between the freezing and boiling points of water. 
• Here 0° represents the freezing point and 100° represents the boiling point. In many countries, celsius is used to communicate day to day temperatures.
• Fahrenheit: The Fahrenheit scale was proposed by physicist Daniel Gabriel Fahrenheit in 1724. 
• This scale is primarily used in the United States and some Caribbean countries to communicate day to day temperatures.

The temperature T in degrees Fahrenheit (°F) is equal to the temperature T in degrees Celsius (°C) times 9/5 plus 32:

$°F={{9\over5}°C+32}$

CALCULATION:

Given that:

Temperature (T) = 0 °C

Use the above-given formula:

$°F={{9\over5}\times0+32=0+32=32°F}$

EXTRA POINTS:

To convert Celcius into Kelvin scale:

K = C + 273.15

• The temperature which shows the same measurement in Celcius and Fahrenheit scale = -40.
• The temperature which shows the same measurement in Kelvin and Fahrenheit scale = 574.25.

The given word is,

Similarly,

Hence ZEBRA is coded as MROEN.
