Ayushman Bharat is a health insurance scheme aimed at providing comprehensive health coverage to Indian citizens.

Concept:

The direct consequences of man-​made climate change include:

• Rising maximum and minimum temperatures.
• Rising sea levels 
• Higher ocean temperatures 
• An increase in heavy precipitation (heavy rain and hail)
• Shrinking glaciers
• Thawing permafrost

The indirect consequences of climate change, which directly affect us humans and our environment, include: 

• An increase in hunger and water crises, especially in developing countries.
• Health risks through rising air temperatures and heatwaves. 
• Economic implications of dealing with secondary damage related to climate change 
• Increasing spread of pests and pathogens
• Loss of biodiversity due to limited adaptability and adaptability speed of flora and fauna  
• Ocean acidification due to increased HCO₃ concentrations in the water as a consequence of increased CO₂ concentrations.

So Ozone layer depletion is not an effect of climate change.

The US House of Representatives has bolstered the Quadrilateral Security Dialogue (Quad) by passing legislation to strengthen ties among the member nations – USA, Australia, India, and Japan.

The point will lie on the line if L.H.S of the equation is equal to R.H.S

Given equation is 2x - y = 5

Put the point ( 2 , -1) in the above equation

2 . 2 - (-1) = 4 + 1 = 5 = R.H.S

So this proves that the given points lie on the line. 

So option D is correct answer.  

Johann Friedrich Gauss, he was a German mathematician who find the sum of the first 100 natural number.

sin 30° = 1/2,
cos 30°=√3/2,
sin 60°=√3/2,
cos 60°=1/2,
By putting the value of sin 30°, cos 30°, sin 60° and cos 60° in equation

We get=
(sin30°+cos30°)-(sin60°+cos60°)=(1/2+√3/2)-(√3/2+1/2)
=0

Option C is correct answer.

For the given point  (2,1)

x = 2 and y = 1

Putting value in 2x + y = 5
2 (2) +1 = 5
5 = 5

So point (2,1) lies on the line 2x + y = 5

Let the angles be x
As they are in ratio of 4:5, so we can write it in the form of 4x ,5x
We know supplementary angle =180°
so,According to the question
4x+5x = 180°
9x = 180°
x = 180° ÷ 9
x = 20°
so, 1 st angle = 4x = 4×20° = 80°
2 nd angle = 5x = 5×20° = 100°
PROOF
4x + 5x = 180°
4×20° +5×20° = 180°
80°+ 100°= 180°
180° = 180°

As chalk is used to write on the blackboard similarly the Ink is used to write on the paper.

First and fouth letters are interchanged while second and third letters are interchanged.

- Analogy Analysis:
- In the given analogy "ZRYQ : KCJB", the relationship can be understood as:
- Z -> K (Z + 2 = K)
- R -> C (R - 3 = C)
- Y -> J (Y - 3 = J)
- Q -> B (Q - 9 = B)
- So, the pattern is adding or subtracting a specific number from each letter in the pair.

- Applying the Pattern:
- Now, applying the same pattern to "PWOV":
- P + 2 = R
- W - 3 = T
- O - 3 = L
- V - 9 = F
- So, the answer should be a word starting with R, T, L, F.

- Finding the Correct Answer:
- Looking at the options:
- A: GBHA
- B: ISJT
- C: ELDK
- D: EOFP
- Among these options, the word starting with the letters obtained from the pattern is "ELDK".

As the young one of a 'cat' is 'kitten' in the same way the young one of 'woman' is 'baby'.

As the cry of 'Dog' is called 'Bark' in the same way the cry of 'Goat' is called 'Bleat'.

The logic followed is:

Therefore, the number of students in the group are 20 + 30 + 70 = 120

The number of students = 120

Hence, the correct answer is "120".
