The correct answer is the Mediterranean Sea.

Key PointsWestern disturbances are extratropical storms that bring sudden winter rain to the northern parts of India. They originate in the Mediterranean Sea. 

Western Disturbances

• Western Disturbances form in the mid-latitude area, situated north of the Tropic of Cancer. This is why they are referred to as mid-latitude storms or extra-tropical storms. 
• Western Disturbances are low-pressure systems, embedded in western winds (westerlies)  that flow from west to east.

Arrival in India

• Western Disturbances begin is a low-pressure system that originates in the Mid-latitude region near the Atlantic Ocean and Europe.
• The low pressure typically forms over the Mediterranean Sea and travels over Iran, Iraq,  Afghanistan, and Pakistan before entering India loaded with moisture.
• These moisture-laden western disturbances eventually come up against the Himalayas and get blocked, as a consequence, the moisture gets trapped and precipitation is shared in the form of snow and rain over Northwest India and other parts of North India. 
• An average of 4-5 western disturbances form during the winter season and the rainfall distribution and amount varies with every western disturbance.
• The word 'Western' refers to the direction from which they originate in India.
• The word 'disturbance' is used because the air within the low-pressure systems tends to be unstable or disturbed.
• When western disturbances become more intense in the Indian Region, they can extend even up to 15 degrees north, resulting in rainfall up to north Maharashtra,  Gujarat, and the entire Madhya Pradesh to the south.

Impact

• Western Disturbances are the cause of most winter and pre-monsoon season rainfall across North-West India.
• This phenomenon is usually associated with a cloudy sky, higher night temperatures, and unusual rain.
• It is estimated that India gets close to 5-10% of its total annual rainfall from western disturbances.
• In winter, western winds bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian subcontinent. 
• India is a rain-dependent country and while the southwest monsoon covers most of India, parts of North India don’t get much rain from it.
• These regions depend upon snow and rain from western disturbances during the winter season from November to March.
• Precipitation during the winter season has great importance in agriculture particularly for rabi crops including wheat, which is one of the most important Indian crops.
• They start declining after winter.
• During the summer months of April and May, they move across North India and at times help in the activation of monsoon in certain parts of northwest India.
• During the monsoon season, western disturbances may occasionally cause dense clouding and heavy precipitation.
• Weak western disturbances are associated with crop failure and water problems across north India.
• Strong western disturbances can help residents, farmers and governments avoid many of  the problems associated with water scarcity.

Additional Information

• The Mediterranean Sea is located between Eurasia and Africa, mostly surrounded by land.
• It shares borders with 21 countries: Albania, Algeria, Bosnia and Herzegovina, Croatia, Cyprus, Egypt, France, Greece, Israel, Italy, Lebanon, Libya, Malta, Monaco, Montenegro, Morocco, Slovenia, Spain, Syria, Tunisia, and Turkey.

Given:

In the given figure, O is the point of intersection of two chords AB and CD such that OB = OD

Concept Used:

According to the chord intersection theorem, the product of two intersecting inside-the-circle chords' segments is equal.

Solution:

Given that, O is where the chords AB and CD converge and  OB = OD

The type of triangles OAC and ODB must be determined.

According to the chord intersection theorem, the product of two intersecting inside-the-circle chords' segments is equal.
As a result, the segment product is: OA x OB = OC x OD

∴  OA = OC and OB = OD.

In ΔOAC, OA and OC lengths are equal.

∴ The triangle is isosceles.

In ΔOBD, OB and OD lengths are equal.

∴ The triangle is isosceles.

Due to the resemblance characteristic, identical triangles have congruent corresponding angles and proportionate corresponding sides.

  (Vertically opposing angles)

OA = OB = OC = OD (radius)

∴ The corresponding sides and angles are equal.

The triangles OAC and OBD are hence comparable.

Hence, the triangles OAC and OBD are similar and isosceles.

Given:

Amit, Bipin and Kaithi can complete a piece of work in 20, 30 and 60 days

Concept used:

Total work = Efficiency of the workers × time taken by them

Calculation:

LCM of 20, 30, and 60 is 60 i.e total work

Efficiency of Amit = 60/20 = 3 units/day

Efficiency of Bipin = 60/30 = 2 units/day

Efficiency of Kaithi = 60/60 = 1 units/day

Now,

1st two days only Amit works 

So, amount of work done = 6 units

3rd day Bipin and Kaithi join 

So, total work on 3rd day = 3 + 2 + 1

⇒ 6 units

So,

In 3 days total 12 units of work is completed

So, effective efficiency = 12/3 = 4 units/day

Time = 60/4 = 15 days

∴ Required answer is 15 days.

Let the age of two persons be 4x and 5x

According to the question,

Age of another person = (60/100) × 5x = 3x      ----(i)

∴ 4x – 3x = 14

⇒ x = 14

∴ Age of three persons in the group = 3 × 14, 4 × 14, 5 × 14 = 42, 56, 70

Average age of the group = (42 + 56 + 70)/3 = 56

∴ The average age of the group is 56

Given

The distance between two pillars of length 16 m and 9 m is x meters.

Two angles of elevation of their respective top from the bottom of the other are complementary to each other.

Concept used

If two angles of elevation are complimentary to each other then H = √ab

Where a and b are the Length of the pillars.

Calculation

AB and CD are two pillars of Length 16 m and 9m.

Let the angle of elevation at B and D be θ and (90 - θ)

Distance between two pillars BD be x metres

IN Δ ABD

Tanθ = AB/BD = 16/x       - - - -(i)

In Δ BDC

Tan(90 - θ) = CD/BD = 9/x

Cotθ = 9/x                       - - - - (ii)

Multiply equation i and ii

⇒ Tanθ × Cotθ = (16/x) (9/x)

⇒ 144/x² = 1

⇒ x² = 144

⇒ x = 12 m

Alternate Method
If two angles of elevation are complimentary to each other then H = √ab

Where a and b are the Length of the pillars.

H = 

H = √144

H = 12 m

Given:

The amount invest by A = 50,000

The amount invest by B = 20,000

Age of A when the business starts = 20 years

Age of B when the business starts = 18 years

B left the business at the age of = 20 years

When A becomes 24 the difference of received amount between A and B = 77,000

Calculations:

The ratio of amount which is invested by A and B = A ∶ B

⇒ 50000 × 4 : 20000 × 2

⇒ 20 : 4

⇒ 5 : 1

Let the share of A and B be 5x : x

∵ Profit will divide into share capital

∴ Total profit shared by them = 6x

∵ A is working partner he take 20% of total profit as his salary

∴ Salary of A = 6x × (20 / 100) = 6x / 5

∴ Remaining profit for A and B = 6x – (6x / 5) = 24x / 5

The remaining profit is divided into A and B according to their capital

∴ A part in the remaining profit

Similarly B part in the remaining profit

Hence the total part of A = 4x + (6x / 5) = 26x / 5

Then the final ratio of A and B = A ∶ B

⇒ 26x / 5 : 4x / 5

⇒ 13 : 2

∴ The total profit = (77000 / 11) × 15 = 1,05,000

Alternate Method 

The ratio of amount which is invested by A and B = A ∶ B

⇒ 50000 × 4 : 20000 × 2

⇒ 20 : 4

⇒ 5 : 1

∵ A is working partner he take 20% of total profit as his salary

∴ 20% = 1 / 5

Here 5 represents the total profit and the 1 represents the A’s salary

Let the total profit be 30

So the salary of A = 30 × 1 / 5 = 6

∴ The remaining profit = 30 – 6 = 24

The remaining profit is divided into A and B according to their capital

∴ A’s part in the remaining profit = (24 / 6) × 5 = 20

Similarly B’s part in the remaining profit = (24 / 6) × 1 = 4

Hence the total part of A = 20 + 6 = 26

Then the final ratio of A and B = A ∶ B

⇒ 26 : 4

⇒ 13 : 2

∴ The total profit = (77000 / 11) × 15 = 1,05,000

According to the given data,

Let X kg of rice costing ₹18 per kg be mixed with 30 kg of rice costing ₹14 per kg = (X x 18) + (30 x 14)

Resultant mixture = 15 (X + 30)

(X x 18) + (30 x 14) = 15 (X + 30)

18X + 420 = 15X + 450

18X - 15X = 450 - 420 

3X = 30 

X = 10 kg

So 10 kg of rice costing ₹18 per kg must be mixed with 30 kg of rice costing ₹14 per kg so that the resultant mixture will cost ₹15 per kg.

Alternate Method 

Let's solve this using the allegation method:

1. The cost of the cheaper rice is ₹14 per kg and the cost of the dearer rice is ₹18 per kg.
2. The mean price is ₹15 per kg.

The formula for the allegation method is:

Substituting the given values into the formula, we get:

Solving for the Quantity of dearer, we get:

Hence, the answer is 10 kg

Given:

After five years,

Priti = 6x + 5

Sonal = 5x + 5

After five years, the ratio will be changed to 7 : 6

 = 76

36x + 30 = 35x + 35

x = 5

Present age of Priti is 6x = 6 × 5 

= 30

Answer is 30.

Alternate Method 

 Given:

Ratio of the Present ages of Priti and Sonal is 6 : 5

After five years, the ratio will be changed to 7 : 6

Calculation:

Present age of Priti is 30 years.

Answer is 30.
