D Correct answer
Explanation

Shopkeeper gives 500g but charges for 580g, so gains 580 - 500 = 80g per transaction. Profit percentage = (gain/actual given) × 100 = (80/500) × 100 = 16%. Note: the base is what is given (500g), not what is charged (580g). Option A is 580/500 - 1 rounded, B is miscalculation, C is 80/400 incorrectly using 400 as base.
