A 50 dollar meal becomes 55 dollars after a 10% increase.✓Bonne réponse
A 120 kilometre trail becomes 90 kilometres after a 25% reduction.✓Bonne réponse
A phone costing 96 dollars after 20% off originally cost 115.20 dollars.
An enrolment of 180 after a 50% rise started at 270.
Explication
For the meal, 55 / 1.10 = 50, and for the trail, 90 / 0.75 = 120, so those statements correctly reverse their changes. The other statements apply a percentage to the final value instead of dividing by the relevant multiplier.
