Bengaluru, known as the ‘garden city,’ faces its worst domestic water crisis. Over 30 localities receive water on a rotational basis every alternate day, with supply lasting only 30-45 minutes. The city, once abundant with 262 lakes, now has only 81 due to real estate development. The remaining lakes are at risk, impacting the city’s water supply. The reliance on the Krishna Raja Sagara reservoir is strained by a weak monsoon, leading to water shortages and skyrocketing tanker prices. Community involvement is crucial for lake preservation.

The RBI’s “Finances of Panchayati Raj Institutions (PRIs)” report analyzes data from 2.58 lakh Panchayats for 2020-21 to 2022-23, highlighting key findings. Panchayats heavily rely on grants (95%) due to limited own revenue sources like property taxes. Inter-state variations in devolution impact socio-economic outcomes. Inconsistent data poses challenges in assessing fiscal health. PRIs struggle with local tax revenue generation due to a limited tax base, administrative issues, and unclear guidelines. Revenue sources include Central and State government grants, and PRIs have the authority to impose taxes and fees.

The correct answer is 4.

Important Points

• Based on historical seismic activity, the Bureau of Indian Standards has categorized regions in India into four seismic zones: zones II, III, IV and V.
• Of these, the most seismically active area is Zone V and the least active is Zone II. 
• There is a history of devastating earthquakes on the Indian subcontinent.
• The key cause for the high frequency and severity of earthquakes is that the Indian plate is driving into Asia at a rate of roughly 47 mm/year.
• India's geological figures indicate that about 54 percent of the land is prone to earthquakes.
• Research by the World Bank and the United Nations predicts that by 2050, about 200 million urban dwellers in India will be vulnerable to storms and earthquakes.
• The most recent edition of India's seismic zoning map given in India's earthquake-resistant design code [IS 1893 (Part 1) 2002] assigns four degrees of seismicity in terms of zone factors for India.
• In other words, unlike its previous edition, which consisted of five or six zones for the region, India's earthquake zoning map divides India into four seismic zones (Zone 2, 3, 4, and 5).
• According to the new zoning map, the maximum degree of seismicity is predicted in Zone 5, while the lowest level of seismicity is correlated with Zone 2.

Venus is the brightest planet. It is brighter than any other planet viewed in Earth’s sky. After the sun and moon, it is the third-brightest object in the sky. Venus is relatively nearby to Earth. Venus has the highest albedo of any major planet in our solar system. Its albedo is close to 0.7. Albedo compares how much light strikes any object and how much it is reflected. Venus 
reflects about 70% of sunlight striking it. So, Venus is the brightest planet.

P, Q, R, S, T, V, W, and Z are sitting around a circle facing at the centre not necessarily in this same order.

i) T is second to the right of R who is third to the right of P.

Mistake Points

Who is used for the second person in a connecting statement.

For example: 

T is second to the right of R who is third to the right of P.

Here, who is used for R and not for T.

ii) S is second to the left of P and fourth to the right of Q.

iii) V who is not an immediate neighbour of P. (This means V cannot sit immediate left or right of P).

iv) Z is third to the right of V 

Thus we can see S is immediate left of Z.

Hence, the correct answer is "Option 3".

Given:

Number of work completed by Rita and Meena = 10 days

Number of work completed by Rita alone = 15 days

Formula used:

Work = Efficiency × Time

Calculation:

LCM of 10 and 15 is 30

Efficiency of Rita and Meena = (30/10) = 3 units/day

Efficiency of Rita = (30/15) = 2 units/day

Efficiency of Meena = [30/(3 – 2)] units/day

⇒ (30/1) unit/day

⇒ 30 days

∴ The required time to complete the work by Meena is 30 days

Let C and D be the position of the aeroplanes.
Given that CB = 900 m,∠CAB = 60°,∠DAB = 45°
From the right △ ABC,
Tan45 = CB/AB => CB = AB
From the right △ ADB,
Tan30 = DB/AB => DB = ABtan30 = CBx(1/√3) = 750/√3
CB = CD + DB
=> Required height CD = CB - DB = 750 - 750/√3 = 250(3 - √3)

Weight of the car = (180 × 7 – 72 × 6) = 828 kg
Hence, Option B is correct.

∠DAC = ∠B + ∠C
(Exterior angle prop. of a Δ ABC)
According to question,
130° = 2A + 3A
5A = 130°

v₁ = speed in first half

D = total distance traveled = 50 km

d₁ = distance of the first half = 25 km

t₁ = time taken in first half

t₁ = d₁ /v₁

t₁ = 25/v₁                                                 (1)

for the second half :

v₂ = speed in second half = v₁ + 10

d₂ = distance of the second half = 25 km

t₂ = time taken in second half

t₂ = d₂ /v₂

t₂ = 25/(v₁ + 10)                                          (2)

given that :

t₁ - t₂ = 5/60                        (5 min in h = 5/60 h)

(25/v₁ ) - (25/(v₁ + 10)) = 5/60

v₁ = 50 km/h

Area of Rectangle = product of length and breadth (L * B)
Area of Parallelogram = A = ½ × d₁ × d₂ sin (y) where d1 & d2 are diagonal and y is the angle of intersection of diagonal.
