Q: What is the average CO2 emission (in Million Tonnes) of the Transport, Industry, and Residential sectors combined?

Correct Answer: Option B (8,000 MT). Total % of Transport (25), Industry (20), Residential (15) = 60%. Amount = 60% of 40,000 = 24,000 MT. Average = 24,000 / 3 = 8,000 MT.

Q: If the Power sector's emissions are reduced by 10% (relative to its own current value) next year, and all other sectors remain constant, what will be the new total national em...

Correct Answer: Option C (38,600 MT). Current Power emission = 35% of 40,000 = 14,000 MT. 10% reduction = 1,400 MT. New total national emission = 40,000 - 1,400 = 38,600 MT.

Q: What is the ratio of the difference in emissions between Power and Industry to the combined emissions of Transport and Agriculture?

Correct Answer: Option A (1:2). Difference (Power - Industry) = 35% - 20% = 15%. Combined (Transport + Agriculture) = 25% + 5% = 30%. Ratio = 15 : 30 = 1 : 2.

Q: What is the central angle of the sector representing Agriculture?

Correct Answer: Option B (18°). Agriculture = 5%. Central angle = 5% of 360° = (5/100) * 360 = 18°.

Q: If Industry emissions were to increase by 20% of their current value due to economic expansion, what would be the new absolute emission of the Industry sector?

Correct Answer: Option B (9,600 MT). Current Industry emission = 20% of 40,000 = 8,000 MT. 20% increase = 20% of 8,000 = 1,600 MT. New Industry emission = 8,000 + 1,600 = 9,600 MT.
