A non-leap year has 365 days
A year has 52 weeks. Hence there will be 52 Sundays for sure.
52 weeks = 52 x 7 = 364 days .
365– 364 = 1day extra.
In a non-leap year there will be 52 Sundays and 1day will be left.
This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday,friday,Saturday, Sunday.
Of these total 7 outcomes, the favourable outcomes are 1.
Hence the probability of getting 53 sundays = 1 / 7.
∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7.

The lymphatic system is the other transport system of human body. It is a complex network of lymphoid organs, lymph nodes, lymph ducts, lymph capillaries and lymph vessels that produce and transport lymph fluid from tissues to the circulatory system.
Lymph is a circulatory fluid like blood. It runs in the lymph capillaries. It is colourless and contains most of the ingredients similar to blood. It does not contain RBC. Lymph mainly contains WBCs and plays an important role in fighting infections. It also contains most of the protiens present in blood. Lymph finally joins into the blood capillaries.

Saponification is the hydrolysis of an ester under acidic or basic conditions to form an alcohol and the salt of a carboxylic acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap.
Example:
Ethanoic acid reacts with alcohols in the presence of a conc. sulphuric acid to form esters.
C2H5OH + CH3COOH → CH3COOC2H5 + H2O

Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.
Volume of the frustum of a cone = (1/3) πh (r12 + r22 + r1 r2)

The Khilafat Movement was launched by Muhammad Ali and Shaukat Ali. Gandhiji saw this as an opportunity to bring Muslims under the umbrella of a unified national movement. At the Calcutta Session of the Congress in September 1920, he convinced other leaders to start a Non-Cooperation Movement in support of Khilafat Movement.
The Khilafat Movement (1919-1924), was a pan-Islamic, political protest campaign launched by Muslims in British India to influence the British Government and to protect the Ottoman empire during the aftermath of First World War. The First World War had ended with the defeat of Ottoman Turkey.
There was a fear that the power of the spiritual head of the Islamic world (Khalifa) would be curtailed. To defend his power, a Khilafat Committee was formed in Bombay in 1919. The Khilafat leaders put pressure . upon the British Government to give better treatment to Turkey.

The following are the various evidences in favour of evolution:
- Homologous organs: Organs with a common basic structural design but with different functions are said to be homologous organ. For example, forelimbs of a frog, lizard, bird and man.
- The forelimbs of man are used for grasping, of lizard for running, of frog for propping up and bird for flying. They have different functions but have same structural pattern.
- Analogous organs: The analogous organs have different basic structure but perform similar functions. For example, the wing of insects and the wing of birds, have a totally different anatomy and origin but they perform the same function of flying in air.
- Evidences from fossils: The fossils also provide evidences for evolution. For example, the fossil Archaeopteryx looks like a bird but it bears a number of other features, which are found in reptiles. This observation provides a clue that birds have evolved from reptiles.

Tourism can be considered as a trade because :
It involves exchange and buying/selling of products.
The products can be defined in terms of holiday packages , hotel rents, means of transport and hospitality etc.
Exchange of cultures take place and these exchanges are in monetary terms.
Foreign tourists visit India for heritage tourism, adventure tourism, cultural tourism, and business tourism and in the same manner Indians visit foreign places.
Tourism can be considered as an industry because:
Tourism is a large scale industry as the money involved in it is very high.
There is near about Rs 21,828 crore of foreign exchange per year.
Large numbers of people are directly engaged in tourism industry, as many as 20 million people.
Promotes national integration and local handicrafts along with culture and heritage.
It has huge chances of expansion.

H2S + Cl2 → 2HCl + S
The O.N. of S increases from -2 to 0. So it is undergoing oxidation and O.N. of Cl2 decreases from 0 to -1. So it is undergoing reduction. Therefore it is a redox reaction.
CuO + H2 → Cu +H2O
In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed. So, the conversion of CuO to Cu is reduction reaction. H2 is getting oxidised to H2O. So, it is oxidation reaction.
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0

We have seen that a quadratic polynomial is of the form:
p(x):ax2+bx+c,a≠0,
We assume that a, b and c are real numbers. In general, this polynomial has two zeroes. For example, the polynomial p(x):x2−3x+2 has the zeroes x=1,2
.For some quadratic polynomials, the two zeroes might be equal. For example, the polynomialp(x):x2−4x+4
can be rewritten as p(x):(x−2)2. Thus, we can say that this polynomial has the two zeroes: x=2,2,
which happen to be identical.
There might also be quadratic polynomials which have no real zeroes. Consider the polynomial p(x):x2+1
. For no real value of x can this polynomial take zero value, which means that this has no real zeroes. Note that this does not mean that the polynomial does not have any zeroes. Of course this polynomial has (two) zeroes – however, those zeroes are just not real numbers.
