When women get into puberty, the ovaries start producing an hormone known as estrogen. Estrogen is responsible for the widening of the female pelvis. The bones of the pelvis are widen by this hormone as a means of preparing the woman for the process of childbirth. The estrogen are also responsible for the deposition of fat on the hip region of women, making them have a smaller waist and more pronounce hip region.

Given:

The given numbers are 0.75 and 1/3.

Concept Used:

LCM of fraction = LCM of numerators/HCF of denominators

Calculation:

Fraction conversion of 0.75 is 3/4.

LCM of numerator = LCM of (3, 1) = 3

And, HCF of denominator = HCF of (4, 3) = 1

Now,

Given:

The given fractions are \(2\frac{1}{3}\) and \(5\frac{1}{2}\)

Concept Used:

LCM of fraction = LCM of numerators/HCF of denominators

Calculation:

The given fractions are in a mixed fraction so first we need to convert it into proper fraction.

Proper fraction of \(2\frac{1}{3}\) and \(5\frac{1}{2}\) are 7/3 and 11/2

∴ LCM of numerator = LCM of (7, 11) = 77

And, HCF of denominator = HCF of (3, 2) = 1

Now,

LCM of (7/3 and 11/2) = (LCM of (7, 11)/ (HCF of (3, 2) = 77/1 = 77

From the question,
Shopkeeper selling a watch for =Rs.11400= Selling price
He loses on selling =5%
Cost price of watch,
CP=Rs.{(100/(100−loss%))×SP}
={(100/(100−5))×11400}
={(100/95)×11400}
=1140000/95
=Rs.12000

Correct answer is (b) Rational number

\(4.\overline{57} = 4.57575757....\)

Any number that is not non-terminating and non-repetitive is an irrational number.

But since the above number is non-terminating but repeating it is rational.

Prime factorization of 15 and 20 is (3 × 5) = 3¹ × 5¹ and (2 × 2 × 5) = 2² × 5¹ respectively. LCM of 15 and 20 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 2² × 3¹ × 5¹ = 60.
Hence, the LCM of 15 and 20 by prime factorization is 60.

Correct answer is (b) 273

The product of L.C.M and H.C.F of two numbers is equal to the product of two numbers.

H.C.F × L.C.M = 39 × 91

13 × L.C.M = 3549

L.C.M = \(\frac{3549}{13}\)

L.C.M = 273.

Concept used:

Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity.

Whole numbers are the part of the number system in which it includes all the positive integers from 0 to infinity.

Integers are the numbers which can be positive, negative or zero, but cannot be a fraction.

Prime numbers are the positive integers having only two factors, 1 and the integer itself. 

Calculation:

From the above definition,

∴ The correct match is A-II, B - III, C - I, D - IV

Closure property of multiplication: If p and q are natural/whole/rational/integer numbers then p × q is also a natural/whole/rational/integer number. Like in the above example, 4 and 9 are natural/whole/rational/integer numbers, so is their multiple (36).

Closure property of addition: The sum of two natural/whole/rational/integer numbers is also a natural/ whole number.

There are different sets of numbers. Two of them are rational and irrational numbers:

• Rational numbers: It is the set of numbers that can be expressed in the form of \({p \over q}\). For example \(2 \over 3\). A rational number can be classified into:
  • Natural Numbers: 1, 2, 3..... up to infinity are natural numbers.
  • Whole Numbers: 0, 1, 2, 3..... up to infinity are whole numbers.
  • Integers: 0, ±1, ±2, ±3...... up to ± infinity are integers.
• Irrational numbers: It is the set of numbers that can not be expressed in the form of \({p \over q}\). For example √3.
• Imaginary Numbers: Those numbers which are written in a + ib form, where i = √-1.

Hence, we conclude that all the above types of number follows closure property.

Images recorded by photographic camera are obtained by chemical process. These images are real and are called optical. They can be black and white or color. The original image formed is called a negative and from it finally finished positive images is obtained. Whereas the images that are formed and it electronic or digital form are virtual. They are stored as an electronic data and can be seen only with the help of a machine. They can be easily duplicated without the fear of any loss of quality. These images can be attached to an email a transmitted and they can be easily stored on variety of locations such as the hard disk, the USB drive, CD, DVD or in cyberspace etc. An optical image can be easily converted Into an electronic one and stored suitably.

If you've ever taken a bite out of a lemon, you already know they pack some serious sour power. This is because they contain citric acid, which is a weak organic acid found in many fruits and vegetables. When you bite into a lemon, the citric acid activates taste buds along the sides and center of your tongue.

A lemon has a pH of around 2. It’s more acidic—and that’s why it’s sour in taste.

Solution: We have, Work done W = 100 J
Charge Q = 20 C
Potential difference V = W/Q = 100 J/20 C = 5 V.
