What percentage of petroleum is petrol?
Think it through first, then pick an option.
- a 2%
- b 5%
- c 10%
- d 13%
Answer and explanation
Correct answer: b 5%
According to the book, petroleum contains 5% petrol (gasoline).
Why the other options are wrong
- a 2%: 2% is petroleum gas's share; petrol is 5%.
- c 10%: 10% is naphtha's share, the fraction next to petrol; petrol is 5%.
- d 13%: 13% is kerosene's share, a bigger fraction; petrol is only 5%.
