RRB Group D Current Affairs Quiz: 27 September 2026

The correct answer is 343 tonnes. The plant in Uttar Pradesh takes in that quantity of organic waste each day and yields about twenty-one tonnes of bio-CNG, along with twenty-eight tonnes of good quality compost that goes to farmers nearby. Its multi-feedstock design accepts wet waste, paddy straw, cattle dung and poultry litter, which is what lets it give crop residue a paying use instead of leaving it to be burnt. Options A at 143 tonnes, B at 243 tonnes and D at 443 tonnes are near misses built by changing the leading digit, a trap that catches a candidate who remembers only the last two digits of the figure. Aspirants should also hold on to the linked numbers for this plant: daily wet-waste supply has risen from seven or eight tonnes to about 125 tonnes, piped gas is expected to reach roughly 45,000 households, and annual emissions are expected to fall by about 57,000 tonnes.

The correct answer is Sabarmati. The first train in India to run on liquefied natural gas was sent on its way from Sabarmati Railway Station in Ahmedabad, Gujarat, by the Union Home and Cooperation Minister, who described the step as useful for protecting the environment. The same station also received a locomotive maintenance shed and the Kavach safety system on the section running to Kalol. Ahmedabad Junction is wrong because the works announced that day were grouped under the Sabarmati division and the flag-off itself took place at Sabarmati, not at the city's main junction. Vadodara is wrong: it was mentioned only as the destination of a trial run by a double-stack long-haul container train that began at the port in Mumbai. Gandhinagar Capital is wrong because no part of the day's announcements concerned that station; the doubling work taken up was on the line from Sabarmati to Sarkhej.

The correct answer is 100 weeks. The campaign against drugs and substance abuse among the young has been designed as a sustained drive of that length, so that awareness work continues instead of ending with a single day or a single week of events. Option A, fifty weeks, would be roughly a year and is the sort of round figure a candidate guesses when the real number is not remembered. Option B, seventy five weeks, echoes the Amrit Mahotsav style of numbering that several other campaigns have used, which makes it tempting but wrong here. Option D, one hundred and fifty weeks, simply stretches the correct figure. Remember the number along with the full name of the campaign and the two volunteer bodies behind it, because a question can be framed on any of the three.

The correct answer is Gwalior, in Madhya Pradesh. Adarsh Gaushala stands at Laltipara and is the city's largest cowshed, home to more than ten thousand cattle. Its compressed bio-gas plant of 100 tonnes per day opened in October 2024, spread over five acres, cost 31 crore rupees and was developed with Indian Oil Corporation. It is also the state's first such plant designed to take vegetable and fruit waste from markets and homes along with dung, and it converts 100 tonnes of dung a day into two tonnes of gas and ten to fifteen tonnes of dry bio-manure. Option A, Bhopal, is the state capital but not the site. Option C, Indore, is widely known for cleanliness rankings, which is exactly why it tempts a guess here. Option D, Jabalpur, is another large city of the same state and has no link to this facility.

The correct answer is Rs 1,472 crore, the combined worth of the works opened and the foundation stones laid at Sabarmati on the day the first LNG-powered train was flagged off. Option A, Rs 700 crore, is only one part of that package: it is what the WAG-12 shed for maintaining locomotive engines cost. Option C, Rs 589 crore, is a very different figure, the total railway spending in Gujarat across the years from 2009 to 2014, quoted to contrast past and present outlays. Option D, Rs 17,366 crore, is the railway outlay for Gujarat in a single year, 2026-27, again used for that comparison and not the value of the Sabarmati works. Only option B answers what was asked, so B is right.

The correct answer is Mera Yuva Bharat, known as MY Bharat, and the National Service Scheme. Volunteers of these two bodies work alongside schools, colleges, universities and various social and spiritual organisations to run pledge ceremonies and awareness programmes under the campaign, and the competitions that feed it are hosted on the MY Bharat platform. Option A names two well known youth organisations that do similar community work, but they are not the two named here. Option C pairs a cadet organisation with a skilling body, and while cadets often join social campaigns, that is not the pairing behind this drive. Option D names an innovation mission and a parliamentary programme, neither of which is a volunteer network of this kind. Candidates should tie MY Bharat and the National Service Scheme to this campaign, since both names recur across youth affairs questions.

The correct answer is Hyderabad. At the Bowenpally Vegetable Market roughly ten tonnes of vegetable and fruit waste is collected each day, and since an on-site biogas plant came up almost all of it is used rather than sent to landfill. The plant makes about 400 to 500 units of electricity and 30 kg of biofuel daily, which run the streetlights, stalls, administrative building and water supply network, while the biofuel goes to the market's kitchen and to a generator that works wholly on biogas. The power bill has come down by about half from roughly three lakh rupees a month, and five more plants have been funded at Gudimalkapur, Gaddiannaram, Erragadda, Alwal and Saroornagar. Options A, B and D are large cities in other states and none of them was named for this model, so they only test whether the candidate has tied the market's name to the right city.

The correct answer is 12,000 horsepower. The engine put into service at Sabarmati is a twin-section machine of that rating, and it can pull on its own a load that would otherwise need roughly 600 trucks. Two locomotives used to be joined together for such a haul, so one WAG-12 now does the work of a pair, which the Home Minister called a landmark for Indian Railways. Options A and B, 6,000 and 9,000 horsepower, are lower ratings that do not match the machine described at the ceremony. Option D, 15,000 horsepower, is higher than the stated figure. A shed costing Rs 700 crore was opened at the same station precisely to maintain locomotive engines of this class, which is why the number is worth remembering with the shed.

The correct answer is Nasha-Mukti Ka Sandesh. This is the strand of the campaign in which young volunteers take the warning against substance abuse into their own communities, speaking in their own languages and using their own forms of creative expression, and it was praised for exactly that reason. Option A, Yuva Sankalp Yatra, sounds like a youth march and borrows familiar words from other youth programmes, but it is not the initiative named. Option C, Swasth Yuva Abhiyan, points at health in general, and although health check-up camps and meditation camps are planned under the campaign, that is an activity and not the name of this initiative. Option D, Sandesh Se Samadhan, reuses the word for message to mislead. Learn the exact name, as questions on campaigns usually test the sub-initiative rather than the umbrella drive.

The correct answer is October 2014. Scientific management of municipal solid waste has been a core objective of the mission since that launch, and as the mission grew, organic waste came to be treated as a resource for clean energy rather than as rubbish. The waste-to-energy work described at Prayagraj, Gwalior, Hyderabad and Gandhinagar all falls under the urban arm of the mission in its second phase. Option B, August 2014, is close enough in the same year to catch a hasty reader, but it is the wrong month. Option C, October 2015, keeps the right month and moves the year by one, the commonest form of trap in date questions. Option D, April 2016, matches neither. A helpful anchor is that cleanliness is tied to the birth anniversary of Mahatma Gandhi, which falls on the second of October, so the month of the launch is easy to fix in memory.

The correct answer is 108 crore litres. The Home Minister said the railways burnt 293 crore litres of diesel in 2015-16 and that the quantity had come down to 108 crore litres by 2024-25, a fall he linked to the spread of electric traction and one he felt received little notice. Option A, 293 crore litres, is the earlier of the two figures, for 2015-16, so it names the starting point rather than the later year. Options B and C, 205 and 150 crore litres, are neither of the two quantities quoted. The same speech put the share of the network already electrified at 99.6 per cent, with the small remainder to be finished soon, which explains why diesel use has shrunk so sharply.
