A democratic country needs a Constitution, because the Constitution serves several purposes. First, it lays out certain ideals that form the basis of the kind of country that we as citizens aspire or live in. Or, put another way, a Constitution tells us what the fundamental nature of our society is. A country is usually made up of different communities of people who share certain beliefs but may not necessarily agree on all issues. A Constitution help serve as a set of rules and principles that all persons in a country can agree upon as the basis of the way in which they want the country to be governed. This includes not only, the type of government but also an agreement on certain ideals that they all believe the country should uphold.  

[17(2 - y) - 5(y + 12)]/(1 - 7y) = 8
34 - 17y - 5y - 60= 8(1 - 7y)
-22y - 26 = 8 - 56y

-22y + 56 y = 8 + 26
34 y = 34

y = 34/34

y = 1

Grains that provides carbohydrates and proteins sufficiently in order to meet the energy needs are called cereal grains. Amost 80% of carbohydrates and 15% proteins come from cereals. The cereal grains are grown worldwide and are major components of food.

These are also known as staple crops because they are rich in energy and boost up the energy level of the body. Cereal is considered to be the most substantial source of food in Asian countries. Some common cereal crops are barley, wheat and rice.

History (from Greek, historia, meaning "inquiry; knowledge acquired by investigation") is the study of the past.

History is all about learning about our past events. This subject needs a clear understanding of the concepts, as it includes lots of dates that need to be memorized. 

125 = 5×25
=5×5×5
=(5×5)×5
=125×5
=5×5×5×5
= 2(5*5)
So, the square root of 125*5 is 5*5
= 25.

Crops sown in the rainy season are called Kharif crops or monsoon crops.  They are sown after the onset of the monsoon. Fertile alluvial soil with a clay layer on top is best suited to grow Kharif crops. West Bengal and Kerala are leading producers of Kharif crops.  

Rice, maize, soyabean, groundnut and cotton are Kharif Crops.

Some farmers follow this process of leaving a piece of land uncultivated for one or more seasons, so that it regains its fertility for the next season. The fallow period also gets rid of pests from the field.

The rearing of fish in large-scale called Pisciculture.
