How much treatment capacity will the sewage treatment plant projects approved under SBM 2.0 add?

The correct answer is Indore. The city set out to keep untreated wastewater out of the environment altogether, and that approach made it the first to be given Water+ certification; today no untreated wastewater flows through its rivers or its natural and man-made stormwater drains. Option A, Surat, took a different route, treating used water as a resource with economic value through tertiary treatment plants and large-scale non-potable reuse. Option C, Navi Mumbai, is notable as the only city in Maharashtra to hold a five-star rating together with Water+ certification, but it was not the first in the country. Option D, Tirupati, has also been declared Water Plus and is known for a revenue-earning plant, again not for being first. Indore’s model went on to encourage several smaller cities.

The correct answer is Jaipur. The Dehlawas plant was built over 22.50 hectares during 2020-23 and has the highest sewage treatment capacity in Rajasthan, at 215 MLD. It is fully automated through a SCADA system and uses a Sequencing Batch Reactor, in which wastewater passes through a Parshall flume, a primary clarifier and a basin before the chlorine tank. Treated water is reused for irrigation and industry, part of it goes to a nearby colony for gardening, and the rest is discharged into the Dravyavati river, with more than 30,000 plants raised around the site. Options A, B and C name other large Rajasthan cities, Jodhpur, Udaipur and Kota, none of which hosts this plant. Link the plant name, the city and the capacity together.

The correct answer is MIDC and WLTP. Reporting under the new CAFE framework will be done on both the Modified Indian Driving Cycle and the Worldwide Harmonized Light Vehicles Test Procedure. Using the two together lets India keep its own established cycle while moving step by step towards the testing practice followed globally, which is why the notification calls it a dual approach. Option B pairs the Indian cycle with an older cycle that the framework does not mention. Option C leaves out the Indian cycle altogether, and option D names procedures that are not part of this notification. For the examination hall, remember both full forms, Modified Indian Driving Cycle for MIDC and Worldwide Harmonized Light Vehicles Test Procedure for WLTP, and remember that the new norms use them side by side rather than replacing one with the other.

The correct answer is the Ministry of Power. The new CAFE norms for passenger vehicles were notified by the Ministry of Power, which handles energy efficiency in the country and works through the Bureau of Energy Efficiency, the body that will administer the credit buyout window under the framework. The norms come into force on 1 April 2027 and run till 31 March 2032. Option A, the Ministry of Road Transport and Highways, frames vehicle safety and registration rules but did not issue this notification. Option B, the Ministry of Heavy Industries, deals with the automobile industry and electric mobility schemes, yet the fuel-economy norms are not notified by it. Option D, the Ministry of Petroleum and Natural Gas, looks after fuel supply and blending programmes such as ethanol in petrol, and although the new framework recognises ethanol-blended petrol through the Carbon Neutrality Factor, the notification itself came from the Ministry of Power. Aspirants should link CAFE norms with the Ministry of Power and the Bureau of Energy Efficiency.

The correct answer is 3.3273 litres per 100 km. Under the new framework the fleet benchmark for fuel consumption begins at 3.996 litres per 100 km in 2027-28 and is tightened year after year until it reaches 3.3273 litres per 100 km in 2031-32. Taken together, that is an improvement of roughly 16.7 per cent in fuel efficiency across the five-year block. Option A, 3.996 litres per 100 km, is the starting figure for the first year of the block and not the end point, so it is wrong. Option C is higher than the opening benchmark, which would mean vehicles burning more fuel rather than less, the opposite of what the norms intend. Option D is far below the notified figure and does not appear in the framework. The safe way to remember it is the pair of figures: the block opens at 3.996 and closes at 3.3273 litres per 100 km.
