4/x + 3y=14 and 3/x - 4y=23
Let 1/x = m,
4m + 3y = 14...(1)
and 3m - 4y = 23 ... (2)
Multiply (1) by 4 and (2) by 3, we get
16m + 12y = 56 ... (3) and 9m - 12y = 69 .... (4)
Adding (3) and (4), we get
25m = 125
→ m = 5
From (1),
4(5) + 3y = 14
→ 3y = 14 - 20
→ y = -2 and m = 1/x = 5 → x = 1/5

The main challenges to sustainable development which are global in character include poverty and exclusion, unemployment, climate change, conflict and humanitarian aid, building peaceful and inclusive societies, building strong institutions of governance, and supporting the rule of law. Other common constraints on development are high economic poverty, hunger, high mortality rates, unsafe water supplies, poor education systems, corrupt governments, war, and poor sanitation. Sustainable development encourages us to conserve and enhance our resource base, by gradually changing the ways in which we develop and use technologies. Countries must be allowed to meet their basic needs of employment, food, energy, water and sanitation.

As per the evolutionary research, there are many factors that lead to the rise of a new species. Listed below are the few factors:
- Genetic drift.
- Natural selection.
- Genetic mutation.
- Geographical isolation.
- Reproductive isolation.
- Environmental factors on the isolated populations.
- Quantum of genetic variant inherited from one generation to the next generation.

Let us assume that √3 is a rational number.
then, as we know a rational number should be in the form of p/q
where p and q are co- prime number.
So,
√3 = p/q { where p and q are co- prime}
√3q = p
Now, by squaring both the side
we get,
(√3q)² = p²
3q² = p² ........ ( i )
So,
if 3 is the factor of p²
then, 3 is also a factor of p ..... ( ii )
=> Let p = 3m { where m is any integer }
squaring both sides
p² = (3m)²
p² = 9m²
putting the value of p² in equation ( i )
3q² = p²
3q² = 9m²
q² = 3m²
So,
if 3 is factor of q²
then, 3 is also factor of q
Since
3 is factor of p & q both
So, our assumption that p & q are co- prime is wrong
hence,. √3 is an irrational number

Constructing a 90º Angle
We can construct a 90º angle either by bisecting a straight angle or using the following steps.
Step 1: Draw the arm <i>PA</i>.
Step 2: Place the point of the compass at <i>P</i> and draw an arc that cuts the arm at <i>Q</i>.
Step 3: Place the point of the compass at <i>Q</i> and draw an arc of radius <i>PQ</i> that cuts the arc drawn in Step 2 at <i>R</i>.
Step 4: With the point of the compass at <i>R</i>, draw an arc of radius <i>PQ</i> to cut the arc drawn in Step 2 at <i>S</i>.
Step 5: With the point of the compass still at <i>R</i>, draw another arc of radius <i>PQ</i> near <i>T</i> as shown.
Step 6: With the point of the compass at <i>S</i>, draw an arc of radius <i>PQ</i> to cut the arc drawn in step 5 at <i>T</i>.
Step 7: Join <i>T</i> to <i>P</i>. The angle <i>APT</i> is 90º.

'a' or the first term=26
and 'd' or the common difference =21-26=-5
n=?
Sum of n terms of A.P=11
Sum of n terms of A.P=n/2(2a+(n-1)d
11=n/2(52-5n+5)
22=n(57-5n)
22=57n-5n2
5n2-57n+22=0
By splitting the middle term,
5n2-55n-2n+22=0
5n(n-11)-2(n-11)=0
(5n-2)(n-11)=0
n-11=0
n=11

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases.
Synucleins are abundant brain proteins whose physiological functions are only poorly understood. The human synuclein family consists of three members – α-synuclein, β-synuclein, and γ-synuclein – which range from 127 to 140 amino acids in length and are 55–62% identical in sequence, with a similar domain organization. Human brain development is created through continuing complex interactions of genetic and environmental influences. Twin studies in adults have found that many aspects of brain anatomy are highly heritable, demonstrating that genetic factors provide a significant contribution to variation in brain structures.
