How many E20 petrol samples were tested and found compliant across 27 States and Union Territories?
- A.456 samples
- B.893 samples
- C.1,250 samples
- D.2,393 samples
Correct answer
Explanation
The correct answer is 893 samples. Under the Quality Coordination Cell exercise of the oil marketing companies and the Centre for High Technology, 893 E20 samples were drawn from depots and retail outlets in 27 States and Union Territories and tested for ethanol content, and every one of them fell inside the prescribed band of 19 to 21 per cent. The samples were split between Indian Oil with 330, Bharat Petroleum with 280 and Hindustan Petroleum with 283. Options A, C and D do not match the figure reported by the ministry. Candidates should also note the Karnataka breakdown within this total: all 56 samples tested in that state conformed to the specification, recording ethanol of 19 to 20 per cent with an average of 19.30 per cent, which is why the ministry rejected the much higher levels alleged in the state's press release.
