Why is accommodation of social diversity and how is it achieved in India ?

Posted by Abc Xyz 5 years, 4 months ago

CBSE > Class 10 > Social Science

1 answers

Gaurav Seth 5 years, 1 month ago

Democracy accommodates social diversity as it allows for equality, fair representation to all irrespective of their caste, creed, colour, race, religion, language or place of residence.

Democracy also ensures that the government should not be made by the majority but it should have the representation of minorities as well

there is a tendency of gender discrimination everywhere in the world Woman are discriminated in one way or the other

India is a secular country and it never tries to give undue preference to any language

Democracy is best form of government to accommodate social diversities if it must fulfills some basic conditions. They are:

Free and fair elections.

Majority rule should not be in terms of religion or race or linguistic groups.

Majority should always work in consonance with the minority.

iters give you a picture of the baker? Our elders are often heard reminiscing nostalgically about those good old Portuguese days the Portuguese and their famous bares of bread. Those eaters of loaves might have vanished but the makers are still there. West After Goa's liberation, people used to say nostalgically that the Portuguese bread crashed with the poders. But the poders have managed to sue because they have perfected the art of door-to- door delivery service. The poders pick up the knowledge of bread making from traditions in the family. The leavened over and bread is a gift of the Partuguese moulders and those who bake the leaves. Those age-old, time-tested fumaces still exist. The fire in the furnaces had not yet been extinguished. The thud and the Jingle of the traditional baker's bamboo, heralding his arrival in the morning, can still be heard May be the father is not alive but the son still carries on the family profession

Prove that 3+√5 is irratonal

Malaika Sharma 5 years, 4 months ago

Let us assume 3+root 5 to be rational.It means that it can be written in the form of p/q where p and q are coprime and q is not equal to zero L.H.S *p/q=3+root5 *p/q-3=root5 L.H.S i.e.p/q-3 is rational but R.H.S i.e. root 5 is irrational So our assumption is wrong Therefore 3+root5 is irrational.

Riya Sharma 5 years, 4 months ago

Let us assume that 3+5 is a rational number. Now, 3+5=ba [Here a and b are co-prime numbers] 5=[(ba)−3] 5=[(ba−3b)] Here, [(ba−3b)] is a rational number. But we know that 5 is an irrational number. So, [(ba−3b)] is also a irrational number. So, our assumption is wrong. 3+5 is an irrational number. Hence, proved.
