Let x be the length of side.

Perimeter = Area

x² = 4x

x = 4

Length of side = 4

The correct answer is Earthquake.

• Earthquake:
  • An earthquake is a sudden shaking or trembling of the earth which lasts for a very short time.
  • It is caused by a disturbance deep inside the earth’s crust.
  • So it is difficult to predict the earthquake.
  • But for the prediction, we use remote sensing.
• Remote sensing
  • It can be used to obtain data of very remote and inaccessible regions. 
  • With the help of remote sensing imagery of any area over a continuous period through which any natural changes in the landscape (earthquake) can be analyzed.
  • The data collected using it is in various forms such as variations in acoustic wave distributions (SONAR), variations in force distributions (gravity meter), variations in electromagnetic energy distributions.
  • The remote sensing is the process of inferring surface parameters from measurements of the electromagnetic radiation (EMR) from the Earth’s surface.
  • In space-borne remote sensing, sensors are mounted on a satellite orbiting the earth.

Explanation:

• Phobos and Deimos are the two moons of MARS that are irregular in shape.
• The moons of Mars are some of the tiniest in the solar system.
• Phobos and Deimos, like Earth's Moon, show the same face as mars. Both are lumpy and heavily cratered, with dust and loose rocks covering them.
• They both are irregular in shape.
• They are among the solar system's darker objects.
• The moons tend to be captured asteroids made of carbon-rich rock mixed with ice.

      1.Phobos : 

• Phobos is marginally bigger than Deimos and orbits Mars at a distance of just 6,000 kilometers.
• There is no known moon that orbits its planet closer. It orbits Mars three times a day,
• Phobos is spiraling inward, drawing closer to the earth by around six feet (1.8 meters) per century. It would either collide with Mars or break up and form a ring around the earth in 50 million years.

      2. Deimos : 

• Takes 30 hours to complete each orbit.
• Outermost moon of Mars
• It is 23,460 kilometers away from mars

Discovery- 

• Asaph Hall discovered the moons of mars in 1877.
• The moon's names were assigned by Hall after the mythological sons of Ares, the Greek equivalent of Mars. Phobos is the Greek word for terror, and Deimos is the Greek word for dread. Fitting titles for a war god's sons.

Sum of continuous n odd numbers = n²

n² = 961

n = √961 = ± 31

Sum of continuous 31 odd numbers

Let x be the number

x² + x = 10 x

x² – 9x = 0

nth term = 3n + (2 – 3) = 3n – 1

(3n – 1)² = 2500,

3n – 1 = 50,

n = 17

square of 17^th term is 2500

Let x be the number,

x² + x = 30

x² + x – 30 = 0, (x + 6) (x – 5) = 0

x = – 6, 5

numbers are – 6, +5

(B) Reserve Bank of india

x² + 2 x = 8

x² + 2x + 1 = 8 + 1

(x + 1)² = 9

x + 1 = 3

x = 2 

Number = 2

Working Capital = Current Assets - Current Liabilities

when working capital is zero;

That means Current assets = Current liabilities

Current ratio =  Current assets / Current Liabilities

will then be equal to 1

(D) Open market

Let x be the age

x + 15 = (x - 15)²

x + 15 = x² - 30x + 225

x² - 31x + 210 = 0

\(x=\frac{31\pm\sqrt{11}}{2}\)

x = 21, 10

∴ age x = 21

Let x be the present age

(x – 15)² = x + 15

x² – 30 x + 225 = x +15

x² – 31x + 210 = 0

Let x be the present age of Laya 

(x – 5)(x + 8) = 30 

x² – 3x – 40 = 30, 

x² – 3x – 70 = 0

\(x=\frac{-3\,\pm\sqrt{9\,+\,280}}{2}=\frac{-3\,\pm\,17}{2}=7,-10\)

Present age of Laya = 7

Let x be the present age .

x + 15 = (x – 15)2

x + 15 = x² – 30x + 225

x² – 31x + 210 = 0

\(x=\frac{-31\pm \sqrt{961-840}}{2}=\frac{31\,\pm\,11}{2}=21,10\)

Present age = 21

The correct answer is Safety pin.

• The safety pin was invented by Walter Hunt.
  • American mechanic Walter Hunt is regarded as the inventor of the safety pin.
  • The safety pin included a clasp that covered the point and kept it from opening and a circular twist at the bend to act as a spring and hold it in place.
  • The safety pin was invented while Hunt was twisting a piece of wire and trying to think of something that would help him pay off a debt of fifteen dollars.
  • It was the first pin to have a clasp and spring action and Hunt claimed
    •  it was designed to keep fingers safe from injury, hence the name.

•  Scooter :
  • The concept of the scooter stretches back at least a century before to 1817 and Baron Karl von Drais de Sauerbrun of Germany. 
• Safety Lamp :
  • The Davy lamp is a safety lamp for use in flammable atmospheres, invented in 1815 by Sir Humphry Davy.
  • It consists of a wick lamp with the flame enclosed inside a mesh screen.

Correct option: c) Co-ordination

ax² + bx - 30 = 0.

x = 15, 225a + 15b - 30 = 0

15a + b = 2 ...... 1

x = -2 4a - 2b - 30 = 0

2a - b = 15 .......2

(1) + (2) \(\rightarrow\) 17a = 17, a = 1

2 x 1 - b = 15 b = -13

Then the equation x² - 13x - 30 = 0

Correct equation is x² - 13x + 30 = 0

\(x=\frac{13\pm\,\sqrt{169-120}}{2},x=\frac{13\,\pm\,7}{2}\)

\(x=\frac{13+7}{2}=10\) or \(\frac{13-7}{2}=3\)

Solutions of the correct problem 10 or 3

(D) only (a) & (b)

’First number = x

Second number = 6 – x

x ( 6 – x ) = 9

6x – x² = 9

0 = 9 – 6x + x²

x² – 6x + 9 = 0

(x – 3)² = 0

(x – 3 ) (x – 3) = 0

x = 3

Numbers are 3, 3.

(D) None of the above

(C) Both (A) and (B)

(D) All the above

(C) MPC + MPS = 1

(B) Manufacturing

x² + 10x - 24 = 0;

x² + 10x = 24;

x² + 10x + 25 = 24 + 25

(x - 5)² = 49;

x + 5 = +7 or -7;

x = 2,-12

(B) Manufacturing

Age of Ammu = x

Age of Divya = x – 7

x(x – 7)+2 = 200

x² – 7x + 2 = 200

x² – 7x – 198 = 0 (x – 18) (x + 11) = 0

x = 18, x = – 11

(age will not be a negative number)

Age of Ammu = 18,

Age of Divya =18 – 7 = 11

(D) All of these

2 + 4 + 6 + .... + 2n = 420

2(1 + 2 + 3 + .... + n) = 420

\(2\times\frac{n(n+1)}{2}=420\)

\(n^{2}+n+(\frac{1}{2})^{2}=420+(\frac{1}{2})^{2}\)

\((n+\frac{1}{2})^2=\frac{1681}{4}=(\frac{41}{2})^2\)

\(n+\frac{1}{2}=\frac{41}{2}\)

n = 20

Sum of 20 even numbers is 420.

In proprietorship organisation, liability of members is unlimited.

Under unlimited liability, if the owner fails to pay the debts of the business, then his/her personal property can be utilised to pay the debt. This implies that there is no difference between the property of the owner and the business. The term “unlimited liability” pertains specifically to a sole proprietorship, as the proprietor is solely liable for the debts incurred by the business.

Investment decision It relates to as how the funds of a firm are to be invested into different assets, so that the firm is able to earn highest possible return for the investors. Investment decision can be long-term, also known as capital budgeting where the funds are commited into long-term basis. Short-term investment decision also known as working capital decision and it is concerned with the levels of cash, inventories and debtors.
Investment decision can be long-term and short-term.

Principal = Rs. 16000; Time = 9 months =3 quarters; 

Rate = 20% per annum = 5% per quarter. 

Amount = Rs. [16000 x (1+(5/100)) 3 ] = Rs. 18522. 

 C.I. = Rs. (18522 - 16000) = Rs. 2522.

Principal = Rs. 10000; Rate = 2% per half-year; Time = 2 years = 4 half-years. 

Amount = Rs [10000 * (1+(2/100))4 ] = Rs(10000 * (51/50) * (51/50) * (51/50) * (51/50)) = Rs. 10824.32. 

∴ C.I. = Rs. (10824.32 - 10000) 

= Rs. 824.32.
