- A.143 tonnes

- C.343 tonnes
- D.443 tonnes
Show answer
Correct answer: C. 343 tonnes
Explanation
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.
