How many NCAP cities have met the National Ambient Air Quality Standards?
- A.14
- B.26
- C.72
- D.108
Correct answer
Explanation
The correct answer is 14. The ministry set out the record on PM10 for the year 2025-26 against the base of the financial year 2017-18 in four steps, and every one of those steps appears among the options here, which is what makes the question worth practising. Option D gives 108, the number of cities that showed any improvement in PM10 levels. Option C gives 72, the cities where the fall in PM10 concentration crossed 20 per cent. Option B gives 26, the cities where the fall crossed 40 per cent. Only 14 cities actually met the National Ambient Air Quality Standards, which is the strictest of the four tests, and that is the answer. Learn the chain in descending order, 108 then 72 then 26 then 14, because the harder the test the smaller the count.
