Answer: 200%.
The idea
Convert units before dividing, and do not be alarmed by an answer above 100% — the first quantity is genuinely larger than the second.
Shortcut. 40 quintals = 4 tonnes, which is twice 2 tonnes — 200%. Converting towards the larger unit keeps the numbers small.
Common trap. 50% — dividing the wrong way (20/40), expressing 2 tonnes as a percentage of 40 quintals.
