24 is the answer

1 Thank You

Yogita Ingle 5 years, 2 months ago (2577571)

6 = 2 × 3

8 = 2 × 2 × 2

12 = 2 × 2 ×3

Therefore the LCM of 6, 8, 12 = 24

We need a three digit number, therefore multiply 24 with natural numbers.

When we multiply 24 with 2, 3, 4 we get only 2 digits.

Therefore multiply 24 with 5.

Now we get the three digit number 120.

Therefore 120 is the smallest three digit number divisible by 6, 8 and 12.

Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated. They occupy the middle portions of the long periods of the periodic table of elements between the groups on the left-hand side and the groups on the right. Specifically, they form Groups 3 (IIIb) through 12 (IIb).

Some of the more well-known transitional metals include titanium, iron, manganese, nickel, copper, cobalt, silver, mercury and gold. Three of the most noteworthy elements are iron, cobalt and nickel as they are only elements known to produce a magnetic field.

The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in picometres or angstroms, with 1 Å = 100 pm. In principle, the sum of the two covalent radii should equal the covalent bond length between two atoms, R = r(A) + r(B).

Durkheim's perspective on religion: • He has defined it as a 'unified system of beliefs and practices related to sacred things that is things set apart and forbidden beliefs and practices which unite one single moral community called a church. • According to Durkheim in every religion a distinction is made between sacred and profane • Sacred things include an element of supernatural. • Profane things are kept at distance from sacred and are considered away from religion

Max Weber's perspective on religion: • He started his theory of religion in his book entitled " The Protestant Ethic and the Spirit of Capitalism” • Calvinism (protestants) exerted an important influence on the emergence and growth of capitalism characterized to earn money and to re-invest profit as a mode of economic organization. • The Calvinist believed that the world was created for the glory of god that any work in this world has to be done for his glory, making even mundane work's acts of glory. • Calvinist also believed in the concept of pre destination which meant whether one will go to heaven or hell was pre ordained. • The money earned was not to be used for worldly consumption rather the ethics of calvinism was to live frugally.

We have unlimited wants and limited resources. For example, If we have more pocket money to spend then we can get all the things according to our wish but if we have less pocket money then we have to choose only those things that we want the most. For example, there are two goods in the economy; wheat and shoes. Then we have to choose the good that we want the most because of limited resources and unlimited wants. Scarcity is the root of all economic problems.
