For a pair of given positive integers ‘a’ and ‘b’, there exist unique integers ‘q’ and ‘r’ such that
a=bq+ra=bq+r, where 0≤r<b0≤r<b
Explanation:
Thus, for any pair of two positive integers a and b; the relation
a=bq+ra=bq+r, where 0≤r<b0≤r<b
will be true where q is some integer.

Assume cube root 6 is rational. Then let cube root 6 = a/b ( a & b are co-prime and b not = 0)
Cubing both sides : 6=a^3/b^3
a^3 = 6b^3
a^3 = 2(3b^3)
Therefore, 2 divides a^3 or a^2 * a . By Euclid's Lemma if a prime number
divides the product of two integers then it must divide one of the two integers
Since all the terms here are the same we conclude that 2 divides a
.
Now there exists an integer k such that a=2k
Substituting 2k in the above equation
8k^3 = 6b^3
b^3 = 2{(2k^3) / 3)}
Therefore, 2 divides b^3. Using the same logic as above. 2 divides b.
Hence 2 is common factor of both a & b. But this is a contradiction of the fact that a & b are co-prime. Therefore, the initial assumption is wrong.
cube root 6 is irrational.

π (Pi) is irrational number.
We cannot write down a simple fraction that equals Pi. The popular approximation of 22/7 = 3.1428571428571... is close but not accurate. Another clue is that the decimal goes on forever without repeating.

Electric Charge is nothing but the amount of energy or electrons that pass from one body to another by different modes like conduction, induction or other specific methods.
An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor.

The criterion used by the UNDP for measuring development is different from the one used by the World Bank in following ways:
i) UNDP measures development on the parameters of education, health and per capita income whereas World Bank measures the same only on the basis of per capita income.
ii) UNDP ranks the countries on the basis of development whereas World Bank classifies them into three categories: rich countries, middle income countries and poor countries.
iii) UNDP has a broader framework to measure development whereas World Bank has a narrow framework to measure the same.

First term is a and common difference is d.
Sum of first and third terms is 10.
t₁ + t₅ = 10
==> a + (1 - 1) * d + a + (5 - 1) * d = 10
==> a + a + 4d = 10
==> 2a + 4d = 10
==> a + 2d = 5 ---- (1)
Ten Terms except for the first term is 99 and except for sixth term is 89.
S₁₀ - First term = 99
==> 10/2[2a + (10 - 1) * d] - a = 99
==> 5[2a + 9d] - a = 99
==> 10a + 45d - a = 99
==> 9a + 45d = 99
==> a + 5d = 11 ------- (2)
Subtract Equation (1) and (2).
a + 5d - a - 2d = 11 - 5
==> 3d = 6
==> d = 2
Place d = 2 in (2).
==> a + 5d = 11
==> a + 10 = 11
==> a = 1
Third term of the progression.
t₃ = 1 + (3 - 1) * 2
t₃ = 5

An object cannot change its state of rest or state of uniform motion in a straight line by itself. In other words, all objects resist a change in their state of rest or motion.
This tendency of objects to resist or oppose change in their state of rest or motion is called inertia.
Mass of an object is the measure of its inertia.

Advantages of Globalisation
(i) Globalisation has resulted in greater competition among producers-both local and foreign. This has improved the quality of products and lowered the prices.
(ii) A wider variety of goods are available in the market for consumers.
Disadvantages of Globalisation
(i) For a large number of small producers, globalisation has posed major problems. These producers were not able to free the competition from large foreign producers and hence several of such production units had to shut down, rendering workers jobless.
(ii) Workers in MNCs are employed on* temporary basis . and laid off without any compensation during the slack period.
