A state electricity report serves as an important tool to assess energy production and track progress in the power sector. By providing quarterly data on generation measured in gigawatt hours (GWh), the report highlights the contribution of different energy sources such as coal, gas, hydro, solar, and wind. This not only helps in understanding the overall energy mix and dependence on conventional versus renewable sources but also enables policymakers, planners, and stakeholders to evaluate trends, address gaps, and promote sustainable energy development. A state electricity report provides quarterly generation (in GWh) by source – Coal, Gas, Hydro, Solar, and Wind.
In Q1
Generation from Coal is 2,200 GWh, Gas contributes 800 GWh, Hydro 900 GWh, Solar 700 GWh, and Wind 400 GWh, for a total of 5,000 GWh.
In Q2
Coal rises to 2,400 GWh, while Gas dips to 700 GWh; Hydro improves to 1,000 GWh, Solar to 800 GWh, and Wind to 600 GWh, bringing the quarterly total to 5,500 GWh.
In Q3
Coal moderates to 2,100 GWh, Gas increases to 900 GWh, Hydro softens to 800 GWh, but Solar advances to 1,000 GWh and Wind to 700 GWh, keeping the total at 5,500 GWh.
In Q4
Coal moves to 2,300 GWh, Gas to 850 GWh, Hydro to 1,100 GWh, Solar to 900 GWh, and Wind to 850 GWh, for a total of 6,000 GWh.
For analysis, Renewables are taken as Hydro + Solar + Wind. A carbon policy scenario proposes cutting Coal by 10%, shifting the entire energy reduction equally into Solar and Wind. (255 words)

Top Questions on Statistical Estimation
- According to the estimates of the World Inequality Report 2022, in India, men earn 82 percent of the labour income, whereas women earn 18 percent of it. A woman agriculture field labourer makes Rs. 88 per day lesser than her male counterpart, according to the Ministry of Agriculture’s data for 2020-21. While a man is paid Rs. 383 a day on an average, a woman makes a mere Rs. 294 a day. The gap in their daily wages is more than the cost of two kilograms of rice. This gap differs from State to State. Field laborers, for instance, make the most money in Kerala. While a man gets Rs. 789 per day, a woman is paid Rs. 537. While this is the highest amount paid to a woman labourer in a State, it is also Rs. 252 lesser than what her male counterpart was paid. As of 2020-21, Tamil Nadu has the highest gender wage gap among agriculture field laborers at 112 percent. It is followed by Goa (61 percent) and Kerala. The wage gap is the lowest in Jharkhand and Gujarat (6 percent each), but the women laborers there get paid just Rs. 239 and Rs. 247 per day, respectively.
Men earn more than women across all forms of work, the gap greatest for the self-employed. In 2023, male self-employed workers earned 2.8 times that of women. In contrast, male regular wage workers earned 24% more than women and male casual workers earned 48% more. The gender gap in earnings is still a persistent phenomenon. However, there are differences in trends. The gender gap has increased for self-employed workers, while falling for regular wage workers. Male regular wage workers earned 34% more than women from 2019 to 2022, with the gap falling to 24% in 2023.- CLAT - 2025

Questions Asked in CLAT exam
- In a language laboratory, students were given an interesting puzzle involving the word "ELECTROCARDIOGRAPH." The teacher explained that such exercises not only test logical skills but also sharpen attention to detail. According to the challenge, the word had to undergo a series of transformations. First, the class was asked to take the first half of the letters, reverse their order and make the arrangement of letters look quite different from the original. Next, the students were told to identify the last but one letter of the original word and place it at the very beginning, a step that changed the opening appearance of the sequence completely. Finally, as a finishing touch, they had to add the letter 'S' at the end. Following these steps carefully would lead them to the correct transformed word, and only those who adhered to each condition in the exact order could solve the puzzle successfully. (150 words)

On the night of October 12th, the "Sunburst Medallion" was stolen from the highly secured display case in the city museum. The theft occurred sometime between the museum closing at 10:00 PM and the night guard, Mr. Hemant, completing his final round at 1:00 AM. Three primary suspects were identified, all of whom had recently been dismissed from their museum positions: Anjali, the former curator; Bharat, the former security expert; and Chitra, the former exhibits designer.
Here are the established facts and their alibis:
- The security system logs show that the display case was opened using a specific five-digit code, which only Anjali and the museum director (who was out of the country) knew.
- Bharat's alibi is that he was at a distant relative's birthday party from 8:00 PM to 1:30 AM. Multiple independent witnesses confirmed his presence throughout the entire period.
- Chitra's alibi is that she was working late at a downtown graphic design studio. A time-stamped security camera from the studio's entrance shows her entering at 7:00 PM and exiting at 11:45 PM. The studio is a 20-minute drive from the museum.
- Mr. Hemant, the night guard, stated he checked the medallion at 10:30 PM, and it was still there.
Further investigation revealed that a small, distinctive silver button was found near the display case. Anjali is known to frequently wear a coat with similar unique silver buttons. The security expert, Bharat, had previously boasted that he could remotely disable a certain type of magnetic lock—the same type used on the medallion's case—without needing the code, though the log suggests the code was used.

In a small town lived a close-knit family where every relation could be expressed through simple symbols. For instance, when they said \( A \times B \), it meant \( A \) is the father of \( B \), while \( A \div B \) meant \( A \) is the mother of \( B \). The younger ones were often introduced with \( A + B \), meaning \( A \) was the daughter of \( B \), and the bond of brotherhood was shown by \( A - B \) (A is brother of B).
One day, the children in the family turned these symbols into a playful code. Instead of introducing their parents and siblings in words, they spoke only in symbols. “Look,” giggled little Meena, “\( M + N \div O \)!” Everyone laughed, because they knew it meant Meena was the daughter of \( N \), and \( N \) was the mother of \( O \), making her \( O \)’s sister. What started as a code soon became a family game, making the bonds of father, mother, daughter, and brother not just relations, but symbols of love and togetherness. (165 words)

Health insurance plays a vital role in ensuring financial protection and access to quality healthcare. In India, however, the extent and nature of health insurance coverage vary significantly between urban and rural areas. While urban populations often have better access to organized insurance schemes, employer-provided coverage, and awareness about health policies, rural populations face challenges such as limited outreach of insurance schemes, inadequate infrastructure, and lower awareness levels. This urban-rural divide in health insurance coverage highlights the broader issue of healthcare inequality, making it essential to analyze the factors contributing to this gap and explore strategies for more inclusive health protection. A state-level health survey was conducted.
The survey covered 1,80,000 adults across urban and rural areas. Urban residents formed 55% of the sample (that is, 99,000 people) while rural residents made up 45% (that is, 81,000 people). In each area, coverage was classified under four heads – Public schemes, Private insurance, Employer-provided coverage, and Uninsured. In urban areas, Public coverage accounted for 28% of the urban population, Private for 22%, Employer for 18%, and the remaining 32% were Uninsured. In rural areas, where formal coverage is generally lower, Public coverage stood at 35%, Private at 10%, Employer at 8%, while 47% were Uninsured.
For this survey, “Insured” includes everyone covered by Public + Private + Employer schemes, and “Uninsured” indicates those with no coverage at all. Officials noted that public schemes remain the backbone of rural coverage, while employer and private plans are relatively more prevalent in urban centres. (250 words)
